2019/5/15 · Owing to the system of monitoring the fouling processes, unscheduled shutdowns of the boiler caused by excessive fouling of the walls of the furnace chamber or superheaters may be avoided. A system for monitoring the operation of a steam boiler based on the developed mathematical model contributes to a significant reduction in the cost of producing 1 kWh of electricity.
Power boiler efficiency is calculated by an indirect method. The local and average degree of the combustion chamber slagging is determined in an "on-line" mode. In the case of superheaters, the fouling coefficient is determined for each superheater stage, due
