Boiler Efficiency and Combustion | Spirax Sarco

A reasonably well-insulated shell or water-tube boiler of 5 MW or more will lose between 0.3 and 0.5% of its energy to the surroundings. This may not appear to be a large amount, but it must be remembered that this is 0.3 to 0.5% of the boiler's full-load rating, and this loss will remain constant, even if the boiler is not exporting steam to

(PDF) Designing of a Fire Tube Boiler - ResearchGate

A fire-tube boiler is a boiler in which fire tubes are immersed in water, and the hot flue gases produced by the combustion chamber flow inside the fire tubes. The hot flue gases transfer their heat to the outside water through the conduction process. When heat transfers to the water, it converts into steam.

Heat losses in the flue gases. This is probably the biggest single source of heat loss, and the Engineering Manager can reduce much of the loss. The losses are attributable to the temperature of the gases leaving the furnace. Clearly, the hotter the gases in the stack, the less efficient the boiler. The gases may be too hot for one of two reasons
