Sichuan Gangchen stainless steel waste heat recovery project
Project overview:
Place: Sichuan Gangchen Stainless Steel Co., Ltd
Introduce: (2) Equipment manufacturing, process pipeline and automation installation project for waste heat recovery device of 70 ton electric furnace production line
Construction content:
Parameters of waste heat boiler (single set):
Annual operation time: 300 days/year
Inlet flue gas temperature of waste heat boiler: 280 ℃~900 ℃
Waste heat boiler flue gas flow rate: 160000~180000Nm3/h
Rated steam production pressure of waste heat boiler (displayed on the gauge): ≤ 2.0 Mpa
Saturated steam pressure at the outlet of the heat storage device (displayed on the gauge): 1.0 Mpa
Saturated steam flow rate at the outlet of the heat storage device (displayed on the table):~20 t/h (continuous)
Saturated steam temperature at the outlet of the heat storage device (displayed on the meter):~184 ℃
Benefit analysis (single set):
Economic benefits (calculated based on steam production):
Annual steam production: 144000 tons/year
Annual income: 144000 × 155=22.32 million yuan/year.
Environmental benefits:
Through heat recovery, a single set of waste heat boiler can save 14400 tons of standard coal per year, which can reduce CO2 emissions by 48600 tons, SO2 emissions by 432 tons, smoke and dust by 210 tons, ash and slag by 1690 tons, etc.
