What is the working principle of the boiler of the industrial boiler of the chemical plant
What is the working principle of industrial boiler in chemical plant? Boiler is a kind of energy conversion equipment. The energy input of boiler includes chemical energy, electric energy, heat energy of high temperature flue gas and so on. After boiler conversion, steam, high temperature water or organic heat carrier with a certain amount of heat is exported to the boiler. Mainly used in thermal power plants, ships, locomotives, industrial and mining enterprises. The main working principle is a kind of heat energy released by boiler fuel combustion after industrial boiler in chemical plant or water transferred to container by waste heat in industrial production, so that the water can reach the required temperature or pressure steam heating equipment. At the same time, the boiler enters the boiler with water entering the boiler, and the heating surface of the boiler is steam- Water system will absorb heat transfer feed water, make hot water reach a certain temperature and pressure or produce hot water or steam, which is introduced into application. Cations. In the part of combustion equipment, fuel combustion continues to release heat, and the high temperature flue gas generated by combustion propagates through heat, which transfers heat to the heating surface of boiler, but the temperature itself decreases gradually, and finally it is discharged through chimneys. What is the working principle of industrial boilers in chemical plants-classification of steam boilers:
First, according to the fuel can be divided into: 1, coal-fired boiler, 2, oil-fired boiler, 3, gas boiler, 4, electric boiler, 5 and atomic energy boiler, 6, waste heat boiler, etc., four topmost, the most common, the lowest operating cost of coal-fired boiler, However, it covers a large area, serious environmental pollution, the requirements of operators, the degree of automation of gas boilers is high, the operating cost is higher than that of coal, the area is small, and less operators are needed. I did not use electric heating boilers. But the operation cost should be the highest, but the boiler covers a small area, environmental protection is the best, other boilers are not introduced, because I do not understand what you mean.
II. According to the heat transfer mode, it can be divided into water tube boiler, thermocouple tube boiler, water tube boiler and fire tube boiler. Oil-gas boiler is generally fire tube boiler, typical type: wns series (horizontal internal combustion chamber combustion boiler), the characteristics of this kind of boiler: simple structure, rated evaporation capacity is generally small (generally 10 tons or less, there are also large, But generally no more than 35 tons), the starting furnace pressure is faster, the boiler water quality requirements are low; Coal-fired boilers are generally water-fired boilers. The thermal efficiency of tubular boiler and water tube boiler is high, but the structure is complex, which puts forward higher requirements for boiler water quality.
