Article Preview

Utilizing multi energy sources synthetically is one of the trends of energy utilization. China has splendid solar energy resource, however, the majority of the electricity production still comes from coal-fired power plants. It is of great necessity to investigate the solar-coal complementary electric generation technology. A 300MW unit thermal-circulation boiler has been studied; calculations about the wall circulation characteristics have been made under 40 conditions. The influence of solar-energy utilization on wall circulation has been analyzed. Calculation and analysis indicated the following: the utilization of solar energy has prominent influences on the steaming point and the under-heating condition of the drum water; the solar energy could be used at high load or low load with the high pressure heaters bypassed conditions, but should not used at 60%-70% load.
