Oct 27, 2016 · A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.
Water pressure systems are made up of a combination of a boiler (also known as a combi boiler) and water storage tanks. Some homes may not have a boiler (the water will be heated by electrical elements in a tank or other heater) but will have hot and / or cold water tanks, and others will have a boiler but no water tanks.
Jun 06, 2016 · Surprised? It’s true. If the load is the same in both cases, the low-pressure steam will move through the pipes much more quickly than the high-pressure steam. The reason is simple: High-pressure steam fits into a smaller space than low-pressure steam. The pressure squeezes it. You wind up with less volume.

Mar 09, 2018 · High pressure is best for most dishes, but low pressure works well for a few select meals. Invented in the 1600s by a French man named Denis Papin who wanted to use new knowledge of physics and steam in cooking, pressure cookers have been around for a very long time.
Difference Between AFBC Boiler and CFBC Boiler AFBC is atmospheric fluidized bed combustion , where the furnace pressure is atmospheric pressure. The flue gas from the furnace goes through a cyclone and is let out to the atmosphere.
Types of High Pressure Boilers. A boiler is a vessel in which water is heated under pressure and vaporized into steam for a specific purpose. There are several different kinds of boilers, heated by coal, solid fuel, oil or gas.
High-pressure boilers will heat steam above 15 psi and water at pressures that exceed 160 psig. Temperatures in high-pressure boilers will exceed 250 degrees F. Because of the elevated pressure at which these boilers operate, they need to be monitored to ensure safety at all times.
Aug 10, 2019 · “Boiler is a closed vessel in which water or other liquid is heated, steam or vapor is generated, steam is super-heated, or any combination thereof, under pressure or vacuum, for use external to itself, by the direct application of energy from the combustion of fuels, from electricity or nuclear energy.
AFBC means atmospheric fluidized bed combustion, where the furnace pressure is atmospheric pressure. CFBC boiler stands for circulating fluidized bed combustion boiler, the furnace is pressurised and the furnace gas is recirculated to capture the unburnt carbon, to increase the thermal efficiency of the boiler. Hence this is an improved version of AFBC. The CFBC boiler has more advantages than AFBC boiler. a. High efficiency.
