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).
