Abstract
HBC imported the design and manufacturing technology of 600MW subcritical boiler with controlled circulation from Combustion Engineering Inc. of U.S.A. (now ALSTOM) in the early 1980s and designed and manufactured China's first 600MW subcritical boiler with controlled circulation in Pinwei Power Plant. With all technical indexes and performance reaching the design data, the boiler was awarded the National Golden Prize for Excellent Product in 1991. During operation, a considerable deviation was experienced between the both sides of gas and steam temperature of SH and RH. The tests revealed the cause for such deviation. The relevant optimized measures were proposed which eliminated the temperature deviation and local overheating, leading to the design of the HBC product of the second generation-#3 and #4 boiler in Panshan Power Plant. With the optimization, the boiler shows better performance.
