China Comprehensive Exhaust Treatment System (DOC+SCR system) for High-power Diesel Generator Sets in North America Manufacturer and Supplier

Comprehensive Exhaust Treatment System (DOC+SCR system) for High-power Diesel Generator Sets in North America

Short Description:

Green Valley DOC+SCR System provides an integrated exhaust treatment solution for high-power diesel generator sets and internal combustion engines. Integrating DOC (Diesel Oxidation Catalyst) and SCR system (Selective Catalytic Reduction) units, the system can simultaneously remove CO, HC, NOₓ and other pollutants in exhaust gas.

The DOC unit converts CO and HC into carbon dioxide and water through catalytic oxidation, and oxidizes particulate precursors in exhaust. With special catalysts and urea solution as reductant, the SCR unit reduces NOₓ into nitrogen and water to achieve high-efficiency denitrification.

The system features compact structure, low back pressure and excellent vibration resistance, complying with emission standards of North America, Europe and other regions. Adopting modular design, it can be customized according to engine power and exhaust parameters. Easy to maintain, it reliably meets emission requirements for off-road internal combustion engines under continuous operation.

Technical introduction

This integrated DOC+SCR comprehensive exhaust treatment project is developed by Green Valley for the North American market. It is matched with the Cummins QSK60-G8 high-power diesel generator set with a displacement of 60L. Integrating DOC (Diesel Oxidation Catalyst) and SCR system (Selective Catalytic Reduction) denitration units, the system provides one-stop treatment for exhaust pollutants of generator sets to meet the strict emission control requirements of California, USA.

After purification by the system, the emission indicators of CO (Carbon Monoxide), HC (Hydrocarbons) and NOₓ (Nitrogen Oxides) in exhaust gas all meet the applicable emission limits of California. Meanwhile, the SCR reaction process is precisely controlled to keep ammonia slip stably within a reasonable range, avoiding secondary pollution and ensuring compliant long-term continuous operation of the generator set.

Technical advantages

The integrated DOC+SCR system features compact construction, low back pressure and excellent vibration resistance, well suited for long-term continuous stable operation of high-power diesel generator sets. With modular design available for customization according to engine parameters, the system is easy to maintain. It consistently meets stringent emission regulations for off-road internal combustion engines in North America, serving as a preferred reliable exhaust purification solution for high-power gensets.
