power plant boiler thermal efficiency calculation method

(PDF) Boiler Calculations | Michael Dellon - Academia.edu

Normally the internal power consumption is about 5 % of the electricity produced by the power plant. Since the power used is electrical (and taken from the grid) the internal power consumption share is reduced from the final boiler efficiency in boiler calculations. Calculating boiler efficiency There are two different means of calculating the ...
