The elevated temperature heat steam that discharges for the steamer power generation system in the prior art generally adopts water-cooled or air cooling.Cooling procedure is the process of changing between the energy of the used heat of system discharging and environment.The heat-transfer coefficient of water-cooled is 1762W(m
2K), to do the heat-transfer coefficient of cooling medium be 62W(m to air
2K).Heat-transfer coefficient has characterized the intensity of diabatic process, and the more big diabatic process of numerical value is more strong.Because the air cooling system heat-transfer coefficient is little, economic efficacy is poor, therefore mainly adopts water cooling system at present.
Water cooling system need consume a large amount of Water Energy as cooling water, and water-cooled still is air-cooledly all the heat in the high-temperature steam of steam turbine discharging can be taken away, the thermal efficiency of thermal power generation on average has only 35%-40% according to statistics, and the energy major part system of being cooled takes away and produces a large amount of used heat, has reduced the utilization ratio of heat.Though can utilize by collecting for the used heat of discharging, but the power station is often distant apart from the urban district, need be with waste heat to a very high temperature of discharging, and then from be transported to the urban district heat exchange station from the power station, because it is a lot of that transport temperature is higher than ambient temperature, therefore the cooling of serious heat loss in transportation process, and thermal expansion is had relatively high expectations to pipeline and relevant device, thereby causes the used heat that can't effectively utilize discharging.
In addition owing to the design for cooling tower in the prior art does not take into full account ambient temperature effect, often cause during the broiling summer, cooling effect descends, overpressure causes generating efficiency to descend in the vapour condenser, if redesign is built new cooling system then is spent higher, thereby and the long economic loss that causes of engineering time, if thereby do not transform then waste a large amount of energy under the generating efficiency.
