Parameters of waste heat boiler (single set):
Annual operation time: 330 days/year
Inlet flue gas temperature of waste heat boiler: 630 ℃ (maximum 900 ℃)
Waste heat boiler flue gas flow rate: 110000 Nm3/h
Rated steam production pressure of waste heat boiler (displayed on the gauge): ≤ 2.4 Mpa/0.3 Mpa
Saturated steam pressure at the outlet of the heat storage device (displayed on the gauge): 1.6 Mpa
Saturated steam flow rate at the outlet of the heat storage device (displayed on the meter): 13 t/h (continuous)
Saturated steam temperature at the outlet of the heat storage device (displayed on the table):~204 ℃
Benefit analysis (single set):
Economic benefits (calculated based on steam production):
Annual steam production: 102960 tons/year
Annual income: 102960 × 155=15.9588 million yuan/year.
Environmental benefits:
Through heat recovery, a single set of waste heat boiler can save 10000 tons of standard coal per year, which can reduce CO2 emissions by 33800 tons, SO2 emissions by 300 tons, smoke and dust by 146 tons, ash and slag by 1174 tons, etc.
