In this article we will discuss about the construction and working of various 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 [...]
