Coal-Fired Power Plant Burner Isolation Valve

One of the most severe problems is the regurgitation of hot furnace gases or a boiler explosion moving backwards through the transfer pipes. Because of the process and volatility of pulverized coal, explosions can happen within the boiler feed system and flow backward as far as the conveyer; therefore, the use of a gate or a valve on the transfer pipes is necessary to prevent the gases or

Development of a Loss Method for Energy and Exergy Audit

Jan 18, 2021 · Results of energy and exergy audition of the boiler by applying the loss method are compared with the direct method. The results show that, although the condensing economizer improves energy efficiency, it does not improve the exergy efficiency significantly. The energy and exergy efficiencies were 98.65% and 5.14%, respectively.
