Two sets of 700KW coal-bed methane generator set flue gas denitrification solutions independently developed and produced by Hebei Hanlan were installed and operated in a mining group in North China and passed the inspection and acceptance. The NOX was successfully reduced from 2000mg/Nm³ to 50mg/Nm³ (5% O2). ) The following expected goals have laid a good foundation for the subsequent in-depth cooperation between the two parties.
The flue gas denitrification system of Wanchun coalbed methane generator set is based on Hebei Hanlan adopts the current international mainstream SCR denitrification process, that is, the principle of using a reducing agent to convert NOX into harmless N2 and H2O under the action of a catalyst. With more than ten years of experience in the field of internal combustion engine exhaust gas treatment, we have developed and designed an integrated denitrification system dedicated to gas-fired distributed energy generating sets.
After undertaking the project, Hebei Hanlan, based on years of experience, compared the customer’s initial investment, post-operation, denitrification efficiency assurance and reliability, and launched a denitrification system in the middle of the two sets of waste heat boilers. The generator set is designed for one-to-one denitration. It has the characteristics of mature technology, low investment cost, low operating cost, short construction period, and easy maintenance. The selected medium temperature catalyst also has the advantages of wide application, stability and reliability, and moderate price.
