To control the pollution emitted by diesel engines Genset, NGT & CPCB set a few parameters to run diesel generators. As per the National Green Tribunal data, Diesel engine operation is one major cause of air pollution. Diesel engines are using 20 to 25% less fuel with cheaper running costs. This feature of diesel Gensets makes them more efficient but there are disadvantages too. When diesel burns, it emits various harmful emission pollutants & toxic gases. According to various studies, diesel engine exhaust is more harmful to the human body & major cause of damage lungs, respiratory problems & cancer.
Keeping in mind all these things, the National Green Tribunal (NGT) issued strict guidelines (a copy of which we have attached below) for the use of retrofitted emission control equipment or devices (RECD). At EO Energy, we provide a custom-designed RetroFit Emission Control System to control hazardous gaseous pollutants released by diesel generators, following all the guidelines issued by NGT, CPCB, and EPCA. Our firm is the largest manufacturer & supplier of emission control devices for DG sets in India.

What is a Retro-fit Emission Control Devices (RECD)?

A retrofit emission control device is installed to reduce the harmful emissions & pollutants exhaust from the diesel generator. In a country where frequent power cut is a normal thing, diesel Genset is widely used for continuous power backup. When diesel burns, it emits unburned hydrocarbons (HC), carbon monoxide (CO), nitrogen oxides (NOx), or particulate matter (PM) into the air. As per WHO, the safety limit of this particulate matter is 23 micrograms per cubic meter. Diesel generators cause the density to increase up to 300 micrograms per cubic meter.
The retrofit device technique adds the extra advantage to control the emission of hydrocarbons and carbon monoxide from diesel generators. The very common retrofitted technology for DG Set is the installation of retrofit devices in the diesel engine exhaust system. The retrofitted equipment installed in the exhaust system controls the emission during the diesel generator operation. These RECDs are built and tested to follow the standards and norms set by NGT, Central Pollution Control Board, Ministry of Environment, Forest, and Climate Change (MoEF & CC).

How a retrofit device attached to diesel generators can reduce air pollution?

In our daily lives, diesel generators play an important role & its widely used as a power backup unit. Also, diesel Genset units are major resources to run industrial & commercial applications during planned or unplanned power failure. There are a number of benefits of having a diesel engine DG Set such as efficiency, cost-effectiveness, high torque & many more. But along with it, they emit harmful gases such as CO2, carbon mono oxide & others which are highly dangerous for our ecosystem.
To control harmful emissions of diesel Gensets, Eoenergy introduced a retrofitted emission control device for DG Set that helps to control the pollution emitted from the diesel engine.

Retrofit emission control technology

The retrofit emission control device is basically a filtration system that filters specific particles. The manufacturing design of this device is a stainless steel box (can) that is mounted with the generator exhaust system. In some cases or with the particular device, they are attached to the original muffler or silencer.
This diesel generator retrofit device is the best way for the proper treatment of pollution control. The device can be easy to install in existing or new diesel generators to control the PM, carbon monoxide, nitrogen oxide & other pollutants particles.
The below reference table will help you to get a better understanding of the various norms of Genset emission.

DIESEL EMISSION REDUCTION TECHNIQUE
Way to Control Diesel Genset Pollution

Retrofit technique

The retrofit technique in diesel generators is the addition of a pollution control device to control the emission rate from the engine exhaust. This trusted technique to remove emissions is very effective & able to reduce more than 90% of pollutant particles in specific cases. The device is used for diesel retrofit along with nitrogen oxide catalysts, diesel oxidation catalysts, exhaust gas recirculation, diesel particulate filters & others.

Repower

Repowering the DG Set is a process where the owner will replace the existing engine with the new one. This technique is more useful when you need to use your device for longer purposes. Repowering any old device gives the opportunity to install a new engine with the latest emission control features. This repower feature of retrofitted emission control devices makes them more useful during operations.

Rebuild

The routine maintenance & replacement of old or faulty parts are the best method to get high efficiency from diesel engine devices. Also, the major maintenance provides an opportunity to rebuild the engine with a more modern technique. Modern engines emit less emission as compared to the old ones or we can say the rebuilt cleaner parts gives immediate emission reduction benefits.

Refuel

There are various fuel types used in the generator. Some of them need a few modifications in the engine or some complete replacement. A few of the alternative fuels such as diesel, biodiesel, ethanol, gas, or propane are used as a supplementary addition to reducing emission.

Replace

Retiring the higher polluting diesel engine device is always the best method to control the pollution level in our ecosystem. So whenever the existing products didn’t match the standard emission level replacing them with the new one is the best technique.

Most Popular Emission Control Devices for Diesel Engine​

Here is the list of the most popular & best emission control device for diesel engines.

Catalytic converter

The catalytic converter is an emission control equipment that converts toxic gases into a less harmful compound. It uses a chamber known as a catalyst. A catalytic converter is placed in the exhaust system next to the engine and looks like a large metal box. It consists of pellets coated with a catalyst and an insulated chamber containing a honeycomb structure.  The converter contains precious metals like platinum, palladium, rhodium.

PCV valve

PCV stands for positive crankcase ventilation. PCV is a one-way valve attached to the crankcase. The crankcase holds the motor oil and is located at the bottom of the engine. When the engine fuel burns, it produces gases. The device uses the engine vacuum to pull air through the crankcase and routes it back into the intake manifold. It burns the gases and fuel safely without harming the environment.

EGR valve

EGR or exhaust gas recirculation valve is used to reduce the formation of nitrogen oxide (NOx) emission. When the combustion chamber temperature exceeds plus 1370℃, it creates harmful gases like nitrogen and passes through the exhaust system to the atmosphere. Exhaust gas recirculation system helps to control the combustion temperature and reduces the formation of NOx and releases more efficient exhaust.

Evaporative emission control

The evaporative emission control (EVAP) system locks the fuel system of the vehicle to prevent fuel vapors from the fuel tank from evaporating in the atmosphere. This is important to prevent the fuel vapor from getting vaporized because it contains various hydrocarbons and forms smog when it reacts to the sunlight. It means if the fuel system opens it pollutes the environment for 24 hours. It is essential to have an EVAP system on our vehicles.

Air injection

An air injection system is an emission control device that forces fresh air into the exhaust ports of the engine to reduce carbon monoxide (CO) and hydrocarbons (HC) emissions. The exhaust gases can contain partially and unburned fuel. Air injection injects oxygen that causes this fuel to continue to burn and reduce the exhaustion of harmful gases like carbon monoxide and hydrocarbons.
