Safety analysis on the water wall in the 350 MW supercritical CFB boiler under sudden electricity failure

The necessity of setting up the emergency water supply system in the supercritical circulating fluidized bed (CFB) boiler is still in controversy in the industry. Based on the research methods in the previous literature and the operating experience, this paper proposed three possible emergency strategies for sudden electricity failure. And by analyzing the physical process in the furnace under sudden electricity failure condition, a mathematical...
