Performance Characteristics Analysis of Supercritical Boiler Water Wall

Abstract:

The key technology of supercritical boiler is water wall, this paper is mainly analyzed the dangerous working conditions of supercritical boiler water wall. On the one hand, from working substance’s point of view, we adopt traditional pressure drop method to judge the heat transfer deterioration position under sub-critical pressure; on the other hand, we use temperature test point combining calculation formula of wall temperature to judge the heat transfer deterioration position under supercritical pressure, and combining improved zoned thermal calculation method to get wall surface thermal load distribution map. Through an instance calculation, when boiler unit under 40% of full load, the maximum thermal load is near 20 meters of furnace height and when it under 100% full loads, the maximum thermal load is near 30 meters of furnace height. So we can control all kinds of heat transfer deterioration position through changing hydrodynamic condition and ward off the highest thermal load area, which is significant to operation.
