Super Critical Thermal Power Plant Boiler Efficienc

V. SUPER - CRITICAL BOILER EFFICIENCY CALCULATION In most large pulverized coal fired boilers, the boiler efficiency loss accounts for about 10 - 15 percentage points 15 of overall plant efficiency loss. If performance is not optimal, the controllable losses can result in an even greater degradation in boiler and overall plant performance.

Online Calculation Method of Boiler Efficiency b

Currently, the most widely used method to calculate boiler efficiency is based on wet basis oxygen which is measured by online instrument, rather than on dry oxygen. Consequently, it often results in the deviation of calculation results, as well as bad adaptability to different kinds of coal. In this study, an online calculation method of boiler efficiency as deducted based on the wet oxygen
