The combustion efficiency of a steam boiler is the measure of how effectively the heat content of the fuel can produce useable heat. The factors determining the efficiency is the amount of unburnt fuels left in the fluegas and the quantity of excess oxygen in the stack gases.

Learn MoreAbstract— This paper is concerned with calculating boiler efficiency as one of the most important types of performance measurements in any steam power plant. That has a key role in determining the overall effectiveness of the whole system

Learn MoreThe efficiency of a process steam boiler/industrial steam boiler is important to a purchase evaluation because the annual cost of fuel can be 2-3 times the installed cost of the equipment. Hence, a difference in efficiency and the resultant difference in fuel cost can offset the difference of installing the product.
