Gas boiler is gas as raw material boiler equipment, gas steam boiler in the industrial field is very widely used, many friends do not quite understand the structure of the gas steam boiler, the following for you to briefly introduce:
1, the boiler body
that is, the boiler's main body part of the package by the steam bag and its attachments, the heated surfaces, the joint boxes, and their associated piping, steam and water system piping And its contact piping, steam system piping and accessories, combustion equipment, smoke and wind piping, frame (including platforms, escalators) and furnace wall.
2, gas burner
By the air supply system, ignition system, monitoring system, fuel system and electronic control system consists of five parts, is responsible for gas delivery to the combustion chamber, ignition of air and fuel mixture, to provide fuel for the steam boiler.
3, control system
Consisting of intelligent central processor and display system, it is responsible for controlling the normal work and operation of the boiler, and facilitating inspection and maintenance.
Two, what is the working principle of the steam boiler
The structure of the steam boiler is not too complex, and its working principle is relatively simple, the specific working principle is:
Working, the heating equipment (burner) to release the heat, the first water-cooled wall through the radiation of heat transfer is absorbed by the water-cooled wall water boiler vaporization, resulting in a large amount of steam into the steam bag for steam separation (DC furnace), the separation of saturated boilers (except for), the separation of water and water, the separation of the saturated boiler, the separation of water and water. (Except for direct-current furnaces), separated from the saturated steam into the superheater, through radiation, convection continues to absorb the top of the furnace and the horizontal flue, the tail flue flue flue heat, and make the superheated steam to reach the required operating temperature. Power generation boilers are usually also set up with reheater, is used to heat the steam after high-pressure cylinder work, reheater out of the reheated steam and then go to the medium and low-pressure cylinder to continue to do power generation.
Three, industrial steam boiler how to classify
1, according to the classification of the quality of work
Can be divided into natural circulation boilers, forced circulation boilers, DC boilers and so on.
2, according to the flue gas flow classification
Water tube boilers, pot shell boilers (fire tube boilers), water fire tube combination boilers.
3, according to the installation mode classification
Quick boiler, assembly boiler, bulk boiler.
4, according to the placement of the cylinder classification
Vertical boilers, horizontal boilers.
5, according to the use of classification
Life boilers, industrial boilers, power station boilers, boilers for vehicles and ships.
6, according to the medium classification
steam boilers, hot water boilers, steam boilers, organic heat carrier boilers.
7, according to the water cycle classification
Natural circulation, forced circulation, DC boilers, composite cycle.
8, according to the pressure classification
Normal-pressure boilers, low-pressure boilers, medium-pressure boilers, high-pressure boilers, ultra-high-pressure boilers.
9, according to the combustion mode classification
Internal combustion boilers, external combustion boilers.
10, according to the fuel classification
Coal-fired boilers, oil-fired boilers, gas boilers, pulverized coal boilers, waste heat boilers, electric heating boilers, biomass boilers.
11, according to the number of boilers classified
Single boiler, double boiler.
12, according to the manufacturing level classification
Steam boilers can be divided into four levels according to the manufacturing level of A, B, C, D. Common A steam boiler pressure is divided into low-pressure boilers, medium-pressure boilers, high-pressure boilers, ultra-high-pressure boilers, subcritical boilers, supercritical boilers.
