The Wanchun coalbed methane generator flue gas denitration system, developed by Hebei Hanlan, adopts the internationally mainstream SCR (Selective Catalytic Reduction) denitration process. This technology utilizes a reducing agent to convert NOx into harmless N₂ and H₂O under the action of a catalyst. Leveraging over a decade of experience in internal combustion engine exhaust treatment, Hebei Hanlan has designed an integrated denitration system specifically for distributed gas power generation units.

SCR Denitration Project Specifications:

Generator Model: ****                                   Number of Units: 3
Power Output: 700 KW                                   Denitration Equipment: SCR-700KW
Fuel Type: Coal Mine Gas (Methane)            

NOx Emission Reduction: From 2000 mg/Nm³ to 30 mg/Nm³

Three sets of 700 KW coalbed methane generator flue gas denitration systems, independently developed and manufactured by Hebei Hanlan, were installed and put into operation at a mining group in North China, successfully passing acceptance tests. The system achieved the expected target of reducing NOx emissions from 2000 mg/Nm³ to below 50 mg/Nm³ (at 5% O₂).

Upon undertaking the project, Hebei Hanlan conducted a comparative analysis based on factors such as initial investment, long-term operational costs, denitration efficiency, and system reliability. The final design positioned the denitration system between two waste heat boilers, adopting a one-to-one denitration configuration for each generator. This solution offers:

Mature technology
Low initial investment
Reduced operating costs
Short construction period
Easy maintenance
The medium-temperature scr catalyst selected for the system is widely used, highly stable, and cost-effective.
