Difference Between Low- and High-Pressure Boilers | HunkerGet Price
The boiler is a closed vessel, where the water is stored. Hot gases are formed by burning fuel in the furnace. These gases are made to come in contact with the water vessel, the point where the heat transfer takes place between the steam and water. Thus, the boiler's basic principle is to convert water into steam with heat energy.Get Price

Because of the heat of water, the pressure at the heat-transfer surface is slightly higher than the pressure at the surface of the water. Because of this higher pressure, the steam bubbles produced at the heat-transfer surface will either leave the boiler slightly superheated or be cooled to the saturation temperature of the water as it rises through the water.Get Price
27/4/2017 · Although they provide high heat transfer due to a combination of high heat transfer coefficients from the base wall and the pins, they also entail high pressure losses. The latter disadvantage is generally not a major issue for convectively cooled blades, where there is availability of higher coolant pressure ratios relative to the surrounding hot gas pressure at the blade trailing edge.Get Price
