D-MEC Technology & Product

Taken the new high-efficiency flue gas circulating fluidized bed technology as core, Longking has integrated DPC pretreatment and ultra-clean fabric filter technology. game ban ca For denitration, one or more combined processes can be applied such as low nitrogen combustion/COA/SNCR/SCR technology. A series of D-MEC solutions such as SSC/ASC/GSC/FSC can be provided for different fields to achieve multi-pollution treatment in flue gas and near-zero emission.

The overall technology has reached the international leading level

71 authorized patents ( 21 invention patents)

Nearly 100 ministerial and provincial awards

600 units of application, the total cumulative output exceeds 20 billion CNY.
