2/2/2016 · It eliminates the need of a boiler drum. 3.2 Advantages of High pressure Boilers  High-pressure boilers use the forced circulation of water which ensures the positive circulation of water and increased evaporative capacity.  They require less heat of vaporization.  They are compact and thus require less floor space.  Due to high velocity of water, the tendency of scale formation is minimized.  All parts are uniformly heated and the danger of overheating is minimized.  The steam can be raised quickly to meet the variable load requirements without use of complicated control devices.  The plant efficiency is increased.  With the use of high-pressure boilers, …
