Construction and Working of Steam Boilers (With Diagram

Construction of Lancashire Boilers: The modern Lancashire boilers are dish ended and welded pattern at least for higher pressures, instead of the older flat ended riveted type. The dish ended construction reduces the tendency of bulging of the end plates and therefore it does not require stays. The flat ended riveted construction of the Lancashire boiler is made of several courses.
