Boiler, also called Steam Generator, apparatus designed to convert a liquid to vapour. In a conventional steam power plant, a boiler consists of a furnace in which fuel is burned, surfaces to transmit heat from the combustion products to the water, and a space where steam can form and collect.
What is the function of boiler in thermal power plant?
Boilers are used in power plants in order to produce high pressured steam, so that the plant can generate electricity. The process that does this is known as the Rankine cycle. The boiler takes in energy from some form of fuel such as coal, natural gas, or nuclear fuel to heat water into steam.
What is the use of boiler?
Boilers are used to produce steam. The generation part of a steam system uses a boiler to add energy to a feedwater supply to generate steam. The energy is released from the combustion of fossil fuels or from process waste heat.
Why is boiler important?
Industrial boilers are one of the most valuable and important assets at most plants and refineries. They play a crucial role in energy production and other industrial processes. Boilers are very valuable assets requiring routine maintenance and inspection because they represent such a sizeable investment.
What is boiler thermal?
A thermal oil boiler fires through a helical coil and generates energy from the hot products of combustion. This, by heating the coil through radiation and convection. … The thermal oil heats coils in various types of heat users. Unlike a water or steam boiler, this heating process does not heavily pressurize the system.
What is the most important part of a boiler?
The safety valve is the most important safety device in a boiler or domestic hot-water system. It is designed to relieve internal pressure if a range of failures occur within the system.
What is boiler capacity?
Since the amount of steam delivered varies with temperature and pressure, a common expression of the boiler capacity is the heat transferred over time expressed as British Thermal Units per hour. A boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as. W = (hg – hf) m (1)
What are the two types of boiler?
When we think about boilers, there are a two types that typically come to mind; firetube, or scotch marine, and watertube boilers. These types of boilers can be classified as hot water, steam, high pressure, and low pressure.
What is boiler efficiency?
Definition of Boiler Efficiency is “The percentage of the total absorption heating value of outlet. steam in the total supply heating value.” In other word, it is a rate how the boiler runs efficiently.
Is boiler a machine?
A boiler or steam generator is a device used to create steam by applying heat energy to water. … A boiler or steam generator is used wherever a source of steam is required.
