What are the different types of Industrial Air Compressor available?

Air compressor enables air pressure control for effective production. Air compressors are diverse in nature with different functionality and applications. Listed below are the different kinds of Industrial Air Compressor.

Types of Industrial Air Compressor

Classification of air compressor can be carried out in different ways but the most popular one is based on the principle of its operation. This way the air compressor is divided into two large categories named – Positive Displacement Air Compressor and Roto-Dynamic Compressor.

Positive displacement compressor classifications

These compressors are further divided into reciprocating and rotary compressor. Reciprocating and rotary compressor can be of various types as stated in the chart.

Reciprocating Compressor Rotary compressor
In-line compressor Screw compressor
V-shaped compressor Vane type compressor
Tandem-piston compressor Lobe and scroll compressors
Single-acting compressor
Double acting compressor
Diaphragm compressor

Rotodynamic compressor

Under this category, we have a centrifugal compressor and axial flow compressor.

Now let us understand the most popular types of air compressors…

Reciprocating In Line Compressor –

This is the most widely used air compressor

Simplest in design

Has a varying pressure tag

Directly driven by electric motors or diesel engines

V-shaped compressor –

Air cooled compressor –

Tips and Tricks for Appropriate Boiler Maintenance

Proper maintenance of a boiler is something every business owner swears by. If neglected, a faulty boiler can lead to various problems. Those, in turn, lead to decrease in production rate. Hence proper boiler maintenance is essential.

It is wise to consult a mechanical utility service provider, if any operational delay is encountered as many options are available in India.

Few tips for the well being of boilers:

  • Regular servicing for boiler and other machines is of utmost importance.
  • For pressurized systems, check and adjust the pressure regularly.
  • Check the central heating timer to ensure proper functioning. In the summer months run the central heating system for 15 minutes, this will prevent the pump from seizing up.
  • The boiler condensate pipe should be correctly lagged otherwise, it may freeze.
  • If there is any black mark, then take expert help immediately as it indicates combustion hazards.
  • Ensure adequate ventilation around your boiler.
  • The pilot light in the boiler should be blue if it turns hazel or yellow ask for expert help.
  • Keep a carbon monoxide detector installed in the room where you have the boiler.
  • Flush the boilers twice a year.
  • If you have an oil boiler, keep an eye on the level of the oil. If it runs out of oil, the system will suck debris and sludge.
  • Keep accurate data log of your boiler operation. Fuel consumptions and fuel gas temperature should be recorded on a daily basis.

Hence, we always advise to take care of the boilers from the day of installation.

How Does A Chiller System Work?

It is important for chillers to use vapor-compression or absorption refrigerant cycle for cooling the fluid for transfer of heat. Three principles are followed: Firstly, when a liquid is heated, it transforms into gas and when the gas is cooled, it condenses into liquid. Secondly, if the pressure is lowered above the liquid, it actually reduces its boiling point and vice versa. Thirdly, heat always flows from hot to cold.

The Three Basic Principles The Chillers Follow to Function Properly

The Working Mechanism of Chillers 

  • Before start up of chiller, check water in cooling tower sump and ensure all valves are open.
  • In most cases the process of cooling applications, a pumping system works actively for circulating cool water or glycol solution. We at Energy Plus provide service for Chiller Operation and Maintenance in India and follow this process rigorously, thus ensuring our services to be envious and smooth.
  • The basic cooling cycle is the same for both vapor-compression and absorption chillers. Both systems utilize a liquid refrigerant that changes phase to a gas within an evaporator which absorbs heat from the water to be cooled.
  • While a vapor-compression chiller consists of four primary components of the vapor-compression refrigeration cycle, an absorption chiller uses a heat source to drive the refrigeration cycle in place of a mechanical compressor.

The chiller will usually be located either in the basement or on the roof and this depends on what type of chiller is used.

For the system to work smoothly with practically no hitch, a reliable service provider is required to operate and maintain the equipment 24×7 as per the manufacturer’s SOP and SMP. This is where Energy Plus’ assistance can come handy in playing a crucial role.

How to Make Your Air Compressor System More Efficient

Compressed air is an important medium for transfer of energy in industrial processes. Proper operation & regular maintenance of Air Compressor can help to improve the system efficiency and reduce operational cost.

Preventive Maintenance of Compressor System:

  • Reduces losses
  • Improves energy savings from compressor system

The Following Should be Maintained:

  • Turn off your air compressors when not needed.
  • Identify and fix air leaks.
  • Eliminate inappropriate uses of compressed air.
  • Apply proper controls to multiple-compressor systems. Master system controls to maintain a stable system pressure. Ensure only the required compressor units are brought online and they are operating at peak efficiency.
  • Ensure that piping and storage are adequately sized.
  • Change compressor inlet air filters on a routine basis to eliminate pressure drop. Every 2 psi in pressure drop reduces compressor horsepower efficiency by 1 percent.
  • Consider automatic, zero-loss condensate drains. Capacitance-sensor-operated drain traps don’t need to be monitored. In addition, they discharge only condensate, not valuable compressed air.
  • Apply variable-speed-drive compressors where appropriate. Variable-speed drive is not a one-size, it fits all solution. However, if demand varies, it can have a huge monetary saving on electricity costs each year.
  • Reduce operating pressure to the lowest possible setting. Every 2 psi reduction in system operating pressure saves 1 percent in compressor efficiency.

Regular maintenance of air compressor includes:

  • Clean inlet air filters, coolant filter
  • Check coolant level
  • Check interlock and condensate drain system

Clean coolers maintain good compressor health.

Safe Operation of a Boiler

IBR Steam Boilers are closed vessel exceeding 25 litres capacity and 1kg/cm2 pressure that are used exclusively for generating steam under pressure. It includes any mounting and or fittings attached to such vessel that is wholly or partly under pressure when the steam is shut off. This causes the boiler to be an extremely dangerous equipment which must be treated with utmost care.

Boiler Maintenance is essential to obtain maximum boiler efficiency. Regular maintenance helps to avert any kind of major break-downs. It is a big savings on overall costs. It is advised to entrust the maintenance work to licensed experts, for a commendable solution and to avert possibilities of mishaps. A scheduled maintenance program extends the life span of the boiler. Below are some important tips to safely operate a boiler:

Tips to Safely Operate a Boiler

  1. Keep A Daily Log For Smooth Operation – The daily log records is very useful to monitor the health of a boiler. Records on operating conditions that includes temperature, pressure, water quality, fuel consumption etc, help to monitor the boiler. These recorded parameters indicate the condition of the boiler, the kind of maintenance required, if any.
  2. Water Level of the boiler is vital and needs to be checked every fortnight or so. Should the boiler operate without adequate water, this can easily damage it beyond repair. Shortage of water in the boiler can lead to serious mishaps and endanger the lives of people. It is to be ensured the pilot light is on as you check the water level. If the water level is below minimum, you need to check the plumbing and correct faults if any. Sometimes, all that is required is a few minor adjustments in the set-up.
  3. Leaks may occur during normal usage of boiler. Gas or fuel leak is serious and calls for immediate attention. This usually indicates some adjustments are necessary in the system. If you detect damaged or worn out parts, it should be replaced or repaired, as the case may be, immediately.
  4. Regular Feed Water & Boiler Water Quality Check and monitoring is important to avoid scale formation in the boiler. Feed water & Boiler water’s TDS, PH & Hardness are critical factors to keep a boiler healthy. Scale formation due to hard water reduces boiler efficiency, increases fuel consumption, leads to heat loss and the possibilities of a mishap.
  5. Burner Maintenance is very important for boiler fuel efficiency. Fuel nozzles, Blower, Fuel pump, Fuel filters are important factors that improve efficiency. If fuel solenoid fails then chances of a mishap is high.
  6. Boiler Tube Cleaning is an important factor to improve boiler efficiency.
  7. Testing of Boiler Safety Mounting and Interlocking to prevent mishaps and increase the boiler health.
  8. Blow Down at regular intervals helps maintain boiler water quality and prevents scale formation.
  9. De-scaling, hard water usually gives rise to excessive lime-scale in the boiler. This prevents the boiler from functioning smoothly. If left to accumulate, lime-scale will hamper the heating capacity of the boiler. You will need to de-scale your boiler should you notice too much lime-scale inside the boiler.
  10. Annual Check & Overhauling is a mandatory practice to have your boiler checked at least once a year by a registered engineer. This ensures the safety and efficiency of the boiler. Any emerging problems can be noted and dealt with accordingly. The license to operate the boiler is issued after inspection.

How to Improve Chiller Plant Efficiency

Chillers are the single largest energy-using component in most industries and can typically consume over 50 percent of the electrical usage. Department of Energy estimates that chillers expend up to 30 percent in additional energy through inefficiency. Chillers running inefficiently also results in decreased equipment reliability, increased maintenance intervals, and shortened lifespan. The slightest decrease in chiller performance can have a major impact on efficiency. For instance, every 1 degree C increase in condenser water temperature above full load design can decrease chiller efficiency by 1 percent to 2 percent. A failing or neglected water treatment program can reduce efficiency 10 percent to 35 percent or more in extreme cases.

What Is Maximum Chiller Efficiency?

Contrary to popular belief, running the chiller at full load design and achieving the design kW/ton does not necessarily mean the chiller is running at maximum efficiency. Maximum chiller efficiency is producing the greatest tonnage at the lowest kilowatt usage. Maximum efficiency occurs with most chillers running at approximately 70-75 percent load and the lowest entering condenser water temperature (ECWT), based on design. Knowing a chiller’s efficiency and the effects of load and ECWT will help the facility determine the most efficient chiller configurations, saving the maximum on energy costs.

Tips to Improve Chiller Plant Efficiency

  • Keep tubes clean for efficient heat transfer: – Heat transfer has the greatest single effect on chiller performance. Large chillers can have more than five miles of condenser and evaporator tubes, so high heat transfer is fundamental to maintaining efficiency.
  • Treat condensate water: – Proper water treatment is required for all condenser water loops. This treatment eliminates scale, corrosion and biological growth. If these elements are found in the system, increase the amount of chemical treatment to the water.
  • Analyze compressor oil: – Once a year, send a sample of the compressor lube oil to a laboratory for a spectrometric chemical analysis that will provide details about moisture content, metals, acids and other contaminants that affect performance. Oil should be replaced only if necessary. High moisture levels can indicate a purge unit problem, which has a significant effect on efficiency. Pull samples from low-pressure chillers more frequently, using a schedule based on purge run hours. Replace oil filters when they exhibit a high pressure drop and when the oil charge is replaced.
  • Reduce entering water temperature: – Lower temperatures of water entering the chiller condenser system will improve efficiency. When cooler water comes into a system, less energy is required to cool the water to a normal operating temperature. Also, if the regulated temperature rises, surging may occur.
  • Maintain a leak free system: – Compressor leak tests should be performed 3-4 times a year. A leak-free system is essential to the performance of a chiller system. Leaks in a system let in non-condensable in the form of air and moisture, which create stress on the system and lead to corrosion. Leaks also release harmful refrigerants into the environment.
  • Install VFD/VSD drive in chiller motor: – The motor in a chiller often draws the single highest electrical load in a facility and variable speed drives minimize energy consumption by syncing the work load and motor efficiency. Variable speed drives also serve as a sort of soft starter function that lowers the initial inrush current. This role is especially important when a chiller is running on emergency backup power systems. LG chillers provide the option to add inverter specifications.
  • Maintain proper water flow rate: – Flow rate must be regulated closely, because too low a flow rate reduces chiller efficiency, leading to laminar flow. The minimum flow rate is typically around 3 ft. per second. However, too high a flow rate leads to vibration, noise and tube erosion. The maximum recommended flow rate is typically around 12 ft. per second.
  • Proper Insulation on chilled water pipeline: – Proper insulation increase the chilling plant efficiency. If insulation is not proper or pipeline is not insulated the heat loss will occurs and overall chilling plant efficiency will comes down.
  • Maintain refrigerant charge: – The amount of cooling that any chiller can provide depends on how much refrigerant it moves through the compressor per unit time. It’s important to maintain the proper level of refrigerant. Leaks, as well as air and moisture, decrease efficiency and system reliability. Low refrigerant charge, usually resulting from leaks, causes the compressor to work harder and achieve less cooling effect.
  • Purge non condensable gases: – Air and moisture are two non-condensable that can leak into low-pressure chillers. Non-condensable can reduce chiller efficiency by as much as 4% at 60% load and 7% at 100% loads. Air insulates tubes, preventing exchange and elevating condensing temperatures, which also makes the compressor work harder. Moisture promotes acid formation, which can damage motor windings and bearings. Installing purge units on low-pressure chillers minimizes the effect of non-condensable. Modern, high-efficiency purge units minimize both air ingress and refrigerant loss. Eventually, positive pressure chillers using HFC-134a, HFC-410a and HCFC-22 will replace low-pressure chillers. The newer units don’t require purge units because non-condensable can’t enter them.
