摘要：Based on the field test and calculation, heat absorption characteristics and steam temperature deviation profile of high temperature heating surface of supercritical circulating fluidized bed (CFB) boilers with different heating surface arrangement were studied. The results indicate that heat absorption shares of the two supercritical CFB boielrs are almost the same in different water stage, and heat absorption share of EHE is about 17.6% in the boiler arranged with EHE. There exits steam temperature deviation at the same tube panel of high temperature superheaters and high temperature reheaters inside the furnace, and deviation among high temperature reheater tube panel is larger. Rational control of enthalpy increment of high temperature tube panels inside the furnace has effect on reduction of steam temperature deviation.
