Boiler refers to the use of fuel combustion release of thermal energy or other thermal energy to heat water or other work materials, in order to produce a specified parameter (temperature, pressure) and the quality of steam, hot water or other work equipment, as an energy conversion equipment, to the boiler input energy in the form of chemical energy in the fuel, electrical energy, high-temperature flue gas heat, etc., and after the boiler converted to the output of a certain amount of thermal energy with the output of steam, high-temperature water or Organic heat carriers. The original meaning of the pot refers to the water container heated on the fire, the furnace refers to the place where the fuel is burned, and the boiler includes two major parts, the pot and the furnace. The hot water or steam produced in the boiler can be directly for industrial production and people’s lives to provide the required thermal energy, can also be converted into mechanical energy through the steam power plant, or then through the generator will be converted into electrical energy mechanical energy.
Provide hot water boiler is called hot water boiler, mainly used for life, industrial production also has a small number of applications. Boilers that produce steam are called steam boilers, often referred to as boilers, mostly used in thermal power plants, ships, locomotives and industrial and mining enterprises.
I. Overview
Boiler is composed of a pot and a furnace, the upper part of the water for the pot, the lower part of the heating for the furnace, the integrated design of the pot and the furnace is called a boiler.
Regulations on Safety Supervision of Special Equipment
The definition of boiler refers to the use of various fuels, electricity or other energy sources, the contained liquid heated to a certain parameter, and the external output of thermal energy equipment.
The scope of its provisions for the volume greater than or equal to 30L pressurized steam boiler; outlet water pressure greater than or equal to 0.1MPa (gauge pressure), and the rated power greater than or equal to 0.1Mw pressurized hot water boiler; organic heat carrier boiler.
