    Water Tube Boiler - Types, Working, Construction

    Aug 28, 2019· Water Tube Boiler is a high-pressure boiler that operates at a pressure of about 165 bar. Basically, in this boiler, water will be flown inside the tubes surrounded by flue gases. More steam is generated by using this boiler so, the overall efficiency of the boiler is high. The water Tube boiler is shown in the figure below.

    Water Tube Boiler - Definition, Components, Working

    A water tube boiler can be defined as a Steam boiler in which the flow of water in the tubes, as well as hot gases, enclose the tubes. Not like fire tube boilers, this boiler attains high-pressures, as well as high-steam capabilities, can be achieved. This is because of condensed tangential pressure on tubes which is known as hoop stress.

    Water-tube or fire-tube condensing - Hot Water Boilers

    The feature that makes water-tube boilers so much safer is the volume of water contained. In a water-tube boiler, it contains a minimal amount of water at any given time. It may be just one-tenth the volume of a fire tube boiler, which requires a larger volume of water to act as a heat shield so that metal in the boiler doesn’t melt and create problems. When fire tube boilers run low on water, the metal in the …
