Lancashire boiler is a fire tube boiler whereas Cornish boiler is a water tube boiler.

Lancashire boiler has two flue tubes and the Cornish boiler has one fiue tube.

Lancashire is horizontal and Cornish boiler is vertical in placement.

Lancashire boiler is externally fired and the Cornish boiler is internally fired.

is easy to fabricate

provides maximum space

gives maximum strength

prevents heat loss

it has a larger bank of tubes and a steam drum

it has longitudinal drum

water passes through the tubes and hot gases flow around the tubes

it has horizontal straight tube with three drum

to regulate water flow

to regulate steam flow rate

to have better contact of flue gases with water tubes

to prevent buckling of water tubes
