Boiler Operations That Affect Efficiency (Part 2)

Boiler Operations That Affect Efficiency. (Excerpted from Steam/its generation and use, 42nd edition) In its simplest form, efficiency is the ratio of energy output to energy input, expressed as a percentage. To optimize efficiency, therefore, it is important to minimize input (fuel being a major source) and maximize output (steam production).

Boiler is one of power plant equipment that has function to produce steam. Thermal boiler efficiency is defined as the ratio of energy output to energy input to produce steam. There are two methods for evaluating boiler efficiency, namely direct method (input output method) and indirect method (heat loss). The experimental method carried out in this study was to conduct experiments and
