The colliery coal-burning boiler raw coal that generally burns, approximately 1.7 tons of 10t/h coal-fired steam chain furnace coal consumptions per hour, slag amount 60%, approximately 900 ℃ of slag temperatures, fall into coke quenching water (or applying after the quenching of cold slag machine) temperature and reduce to 70 ℃ of left and right, slag specific heat 0.96kj/kg ℃, slag thermal discharge per hour is calculated as follows:
Qj＝CMΔt＝1700×0.96×(900-70)＝1354560(kj)，
1354560×0.0002778＝376kW，
Three the boiler slag heat that provides per hour: 376 * 3=1129 (kWh).
According to slag cooler, reclaim and calculate: slag cooler organic efficiency 85%, separate unit electrical power 1.5kW, reclaims heat Calculation as follows: 1129 * 0.85 – 1.5 * 3=955 (kWh)
Design heat is reclaimed and is calculated by cast iron coil pipe: slag and water surface Contact heat of evaporation loss 50%, water surface heat radiation 20%, spermiation close cast iron grid hot coil and boiler replenishing water heat exchange in coke quenching water, by 50% absorption heat Calculation absorption heat per hour be: 1129 * 0.3 * 0.5=169 (kWh).
4, water film dedusting circulatory pool heat recovery is calculated
Evaporation capacity is the Industrial Boiler of 10t/h, and in level pressure situation, the actual water film dedusting water yield is about 18.5m3/h, the heat Calculation that water film dedusting water is per hour absorbed:
Q＝C×M×Δt＝18500×4.186×﹙43–22﹚＝1626261(kj)
1626261×0.0002778＝451(kwh)。
Three the boiler water film dedusting heat that provides per hour: 451 * 3=1355 (kwh).
If heat reclaims wherein 30% heat by cast iron coil pipe, available energy is: 1355 * 0.3=406 (kWh).
