Illustrate
With two kinds of cooling waters of certain hot rolling mill is that example is calculated and analyzed:
1. high-pressure cooling water
Pump group water pump quantity: 7 (5 usefulness 2 are equipped with), separate unit power: 800kW, lift: 125m
Water flow: 2.17m3/s, but discharge water amount: Q=2.17m3/s*0.8=1.73m3/s intermittently during steel.
So generated output: P=9.81 η QH=9.81*0.9*1.73*125=1909 (kilowatt)
η is the efficient of hydraulic turbine generator in the formula, and Q is a water flow, and H is that head is a lift.If the production time in hot rolling mill year, intermittent discharge water was by 3500 hours (actual meeting was greater than 3500 hours), then by 7000 hours:
Annual electricity generating capacity: E=P*T=3500*1909=6682450 (kilowatt hour)=668.245 ten thousand degree
2. laminar cooling water
Pump group water pump quantity: 8 (6 usefulness 2 are equipped with), separate unit power: 315kW, lift: 30m; Discharging head: 25m
Water flow: 4.17m3/s, but discharge water amount: Q=4.17m3/s intermittently during steel
So generated output: P=9.81 η QH=9.81*0.9*4.17*25=920 (kilowatt)
Annual electricity generating capacity: E=P*T=3500*368=3221481 (kilowatt hour)=322.15 ten thousand degree
Build hot rolling or the overflow of CSP cooling water discharging power generation system and can utilize original factory building and pipeline, only suitable processing is done on the hydroelectric facility basis and increase is cooled off the relevant pipeline of overflow discharge water power generation system with hot rolling or CSP, thus civil engineering partly to take investment very low.About totally 100 (there are 3 cover hot rollings and 1 cover CSP in domestic existing hot rolling or CSP factory as Wuhan Iron and Steel Plant only).Hot rolling or CSP cooling overflow discharge water power generation system total investment for construction: ten thousand yuan of 200-400, so economic benefit and social benefit are very considerable.
Hot rolling or CSP cooling water overflow discharging power generation system are mainly used in and reduce the main line need for electricity, promptly needn't directly incorporate the big network system of country into.
