Description

technical field [0001] The invention relates to a steam soot blower soot blowing system of a power plant boiler, in particular to a steam soot blower steam source energy-saving optimal control and fault online monitoring system and method. Background technique [0002] In the steam soot blowing system of power plant boilers, the traditional steam soot blowing steam source interface is designed according to the different situations of the boiler unit. box, the superheated steam parameters in these positions have high pressure and high temperature, while the steam parameters required for soot blowing by steam soot blowers are relatively small in pressure and temperature. Only the steam temperature required for soot blowing in air preheaters is relatively Higher, this will cause energy waste of high-quality superheated steam source, and also cause a large pressure difference between the front and rear of the regulating valve on the steam source pipeline, which will aggravate th...
