Boiler Fuel Oil Commissioning Procedure1.Overview ZMTP 2150MW2510t/h

The project is Zambia ZMTP 2150MW coal fired power plant, located at Maamba coal mine, Sinazongwe, Southern Province. The boiler is produced by Dongfang Boiler Company, which is 2*510t/h high temperature, super high pressure circulating CFB boiler. Here the procedure is for the boiler fuel oil system commissioning.41.35t/h,3.0MPaThe boiler adopts high energy igniter to fire light oil, and then fire coal. Combined firing mode is adopted above bed and under bed, where four mechanical atomization oil guns are set, with output of 1.35t/h and inlet pressure of 3.0MPa. 2.

2.2Fuel oil system regulation and main equipment technique parameter 500m33100%21350%,222The project is provided with light oil tank with effective volume of 500m3. Oil supplying system owns 3*100% capacity oil pumps, two in operation and one in standby. 3*50% capacity oil discharge pumps are installed to meet tank truck unloading requirement, in which two oil discharge pumps can fill two oil tanks in two hours. And one contaminated-oil pump and sewage pump are installed. Oil contaminated-oil basin shall accept and purify the waste oil from light oil tank, various oil pumps and filters, which the purified oil shall be sent to oil tank by contaminated-oil pump, and the left waste water shall be sent to sewage disposal plant by sewage pump. Stationary foam firefighting facilities and spray water system shall be installed on fuel oil tanks to extinguish fire or reduce oil tank temperature in hot weather. Oil pump recirculation pipe is installed at outlet of light diesel oil pump; a tube shall be set between oil supply pipe and oil return pipe in front of the furnace to be used when blowing pipe or oil circulation. Air blowing system shall be necessary for light diesel oil system, and the blowing adopts relay and fixed-direction mode. The fuel oil system shall be cleaned up by blowing, as well as fire cutting on oil pipes. The connection between blowing pipe and oil pump back the pump shall be fixed, where the cut-off valve and non-return valve shall be set to prevent compressed air system polluted by fuel oil contamination.
