35MW Gas-fired Hot Water Boiler Heating Project of Lanzhou Thermal Power Group

Lanzhou Thermal Power Group Co., Ltd. mainly adopts the heating pipe network of power plants, supplemented by the heating production of large-scale peak-shaving heat source plants. At present, the actual heating area has reached 53.986 million square meters, and the heat users include 740 enterprises and institutions including the government and army departments and 500,000 households.

According to the investigation by the EBICO professional team, before renovation, the two stations’ NOx emission has exceeded 150mg, the fuel combustion status was unstable and the cost saving was minimal. Aiming at the emission target that the final NOx should be less than 30mg, EBICO has formulated a complete set of solutions with three new EC-GR series low-nitrogen burners and supporting facilities for Lanzhou Thermal Power.

This product series is rational in shape and structure. The technologies of staged supply of oxygen for central fuel and the peripheral fuel, and negative oxygen burning, can have the fuel controlled at an ideal state, avoiding the forming of high-temperature accumulation zone, which obviously controlled NOx and CO emissions and successfully completes the annual heating work.
