Boiler small knowledge
The definition of boiler: the use of fuel combustion release of thermal energy or other heat heating water or other working medium, in order to produce the specified parameters (temperature, pressure) and quality of steam, hot water or other working medium equipment.
Boiler is a kind of energy conversion equipment. The energy input to the boiler is in the form of chemical energy, electric energy, and heat energy of high-temperature flue gas in the fuel. After the boiler conversion, it outputs steam, high-temperature water or organic heat carrier with certain heat energy. In the boiler equipment, the part that absorbs heat is called the pot, and the part that generates heat is called the furnace. For example, the heat-absorbing parts such as water-cooled walls, superheaters, economizers, etc. can be regarded as pots; and furnaces, burners, fuel pumps, and induced draft fans can be regarded as furnaces. Modern boilers are not as clearly divided as the pots and furnaces used by ordinary families. For example, the air preheater is both a heat absorbing part and a heat generating part, which can be regarded as part of the pot or part of the furnace.
Boiler parameters are the main indicators of boiler performance, including boiler capacity, steam pressure, steam temperature, feed water temperature, etc.
