Abstract
Two integration solutions were put forward,which heat the condensate or feed water of the coal-fired unit by using type of LS-3 parabolic trough solar energy collector, the economic performance of the unit such as type N300-16.67/537/537, N600-24.2/566/566 and N1000-25/600/600 has been evaluated respectively. The results show that coal saving investment ratio (the ratio of coal saving to investment) of small capacity coal-fired unit is larger, more coal saving, less investment cost, comparing with large capacity units;The thermal economy of integration system improves with increasing flow rate of the condensate water (feed water) through the auxiliary heating solar system, coal saving investment ratio is just the opposite;To heat the water from the water pump outlet to economizer inlet by the solar collectors is better to increase the thermal economy and decrease the investment cost. N300-16.67/537/537 type unit saves coal 3.29 g/kWh at solar radiation intensity of 1 000 W/m2 and the flow rate of 5%.关键词
