There are eight types loss in Boiler

Question

Accepted Answer

There are eight types of losses in a boiler.

The eight types of losses in a boiler are: radiation, convection, exhaust, blowdown, incomplete combustion, unburnt fuel, ash, and moisture.
Radiation loss occurs due to the heat radiated from the boiler's surface.
Convection loss occurs due to the heat carried away by the flue gases.
Exhaust loss occurs due to the heat carried away by the exhaust gases.
Blowdown loss occurs due to the removal of hot water and steam from the boiler.
Incomplete combustion loss occurs due to the incomplete burning of fuel.
Unburnt fuel loss occurs due to the fuel that is not burnt completely.
Ash loss occurs due to the unburnt ash that is carried away by the flue gases.
Moisture loss occurs due to the moisture present in the fuel that is evaporated during combustion.

Accepted Answer

L1– Loss due to dry flue gas (sensible heat) L2– Loss due to hydrogen in fuel (H2) L3– Loss due to moisture in fuel (H2O) L4– Loss due to moisture in air (H2O) L5– Loss due to carbon monoxide (CO) L6– Loss due to surface radiation, convection and other unaccounted*.
