Mechanical Education. Header Ads. Lancashire Boiler is invented by Sir William Fairbairn in In Lancashire Boiler the flue gases flow through the fire tube, situated inside the boiler shell, so this is called fire tube boiler. Lancashire Boiler generates low-pressure steam. Construction of Lancashire Boiler: This has two tubes inside the boiler, in this water is filled up to half of the drum due to the remaining space is covered by the help of generated steam, as same as the Cornish boiler to prevent the flow of ash into the tubes bricks are used. By this process, the heat in the gases can transfer up to the maximum.

Lancashrie boiler is a horizontal internally fired, natural circulation fire tube boiler. This boiler rises steam upto a pressure of its bar and maximum evaporating capacity of Kg of steam per hour. This boiler is very widely used in sugar mills and chemicals products industries where the steam is required for processing work. The boiler consist of a horizontal shell placed on a brick work tubes of diameter about 0. In each of these flue inside of their front end.

Lancashire boiler is a horizontal drum axis, natural circulation, natural draft, two-tubular, low pressure, stationary, fire tube boiler with furnace located internally. Its main purpose is to create steam and then this steam is used to drive steam turbines for power generation. It has high thermal efficiency and it is about 80 to 90 percent. It is mostly used in locomotive engines and marines etc. It is used to blow off the steam when the pressure of the steam inside the boiler exceeds the working pressure. It indicates the level of water in the boiler.


Basic Principle of Lancashire Boiler: This boiler consists of a horizontal cylindrical shell filled with water. It uses to surround by two large fire tubes. Heat.
