Fault Diagnostics on Steam Boilers and Forecasting

2016-12-2 · The slagging/fouling due to the accession of fireside deposits on the steam boilers decreases boiler efficiency and availability which leads to unexpected shut-downs. Since it is inevitably associated with the three major factors namely the fuel characteristics, boiler operating conditions and ash behavior, this serious slagging/fouling may be reduced by varying the above three factors.

A modeling method of the coal-fired utility boiler for a 300MW thermal power plant based on energy balance is presented. Key work sections of the power plant are treated as lumped parameter systems and a first-order model with time delay is used to describe the dynamic characteristic of the entire system. As model validation, comparison between model simulations and the actual process data for
