Our Retrofitted Emission Control Device (RECD) systems for DG sets are designed to effectively reduce harmful emissions and ensure compliance with CPCB norms in India. RECD systems have emerged as mandatory requirements for industries commercial establishments and hospitals which operate diesel generators as their backup power source because of increasing air pollution problems and more stringent environmental protection laws.
At Gyarash, the RECD solutions use advanced emission control technology to capture particulate matter (PM), carbon monoxide (CO), and nitrogen oxides (NOx) directly from exhaust emissions which leads to substantial improvements in air quality. The systems provide a cost-efficient solution for pollution control because their installation process on existing DG sets creates an environmentally sustainable solution which organizations can expand throughout their operations.
Working of RECD System
A Retrofitted Emission Control Device (RECD) system operates through advanced filtration and catalytic processes which treat exhaust gases before they exit into the atmosphere. Diesel generators produce exhaust gases during their operation which contain dangerous pollutants that include fine particulate matter and toxic gases. The RECD system operates through its installation in the exhaust line which uses high-efficiency filtration media and oxidation catalysts to capture and filter pollutants.
The system retains particulate matter through exhaust passage while it decreases harmful gases through chemical reactions which target carbon monoxide and hydrocarbons. The system releases only cleaner processed air into the atmosphere because of this procedure. The system establishes optimal airflow conditions which allow the DG set to operate at peak efficiency while achieving maximum emission reduction.
Benefits of Installing RECD System
The installation of a RECD system for diesel generators leads to three main advantages which include major decreases in air pollution, better achievement of governmental standards and safer work environments. The system enables industries to manage emissions from their facilities while minimizing their negative effects on nature and creating cleaner air in both cities and industrial zones. The systems are built to withstand use over time without needing maintenance which makes them a dependable solution for managing emissions throughout their entire operational life.
Different types of emission control devices for DG sets are used depending on the level of pollution, application, and compliance requirements. Each technology is designed to target specific pollutants which leads to better air quality results.
Diesel Particulate Filter (DPF)
The Diesel Particulate Filter (DPF) serves as an extremely efficient method for controlling particulate emissions from diesel generators. The system operates by capturing tiny particles which include soot and ash that result from exhaust gases, before they escape into the environment. The system achieves ongoing operation through a regeneration process which burns off accumulated particles over time. DPF systems effectively lower PM2.5 and PM10 emissions, which makes them suitable for industries that need to comply with high emission control requirements.
Diesel Oxidation Catalyst (DOC)
The Diesel Oxidation Catalyst (DOC) works to decrease the emission of dangerous gases which includes carbon monoxide (CO) and hydrocarbons (HC) from DG sets. The system employs a catalytic chemical reaction to transform toxic gases into safer products which include carbon dioxide and water vapor. DOC systems are often used in combination with other emission control devices to enhance overall efficiency and ensure better compliance with environmental norms.
Electrostatic Precipitator (ESP)
The Electrostatic Precipitator (ESP) system uses electrically charged plates to eliminate tiny particles from exhaust emissions through its advanced pollution control mechanism. The system enables particles in exhaust streams to acquire electrical charges which then draw them to collection plates that possess opposite charges for complete particle collection. ESP systems operate with exceptional efficiency in industrial facilities which need to operate continuously while handling large volumes of emissions.
Selective Catalytic Reduction (SCR)
The Selective Catalytic Reduction (SCR) system functions as an advanced emission control technology which enables diesel generator (DG) sets to cut down their nitrogen oxide (NOx) emissions. The system functions through exhaust stream injection of a urea-based solution called AdBlue which the catalyst uses to transform NOx into harmless nitrogen and water vapor. The technology enables operators to meet strict CPCB emission standards common in India because it functions as a primary NOx control system for industrial applications. The system works with other technologies such as DPF and DOC to form a complete emissions control system for DG sets.
