Boiler Efficiency: Introduction and Methods of Calculation

Steam Basics – Boiler Efficiency. The Efficiency of a boiler should be an important part of a purchase evaluation since the annual cost of fuel can easily be 2 to 3 times the installed cost of the equipment. Therefore, a difference in efficiency and the resultant difference in fuel cost can easily offset a difference in capital cost. In many cases, the fuel savings in the first year alone can exceed a difference in capital cost and, of course, fuel …

Fire-tube boiler - Wikipedia

A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.. The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure tank
