Explosion doors mainly use their own weight or strength. When it is greater than or equal to the total pressure acting on the furnace at normal pressure, the explosion-proof door is closed. When the furnace pressure changes, the total pressure acting on the explosion-proof door exceeds the weight and strength of the explosion-proof door itself, the explosion-proof door will be flushed or broken, and a part of flue gas in the furnace will be released, thus achieving the purpose of pressure relief.
There are many kinds of industrial boilers, for example, according to the boiler pressure, it can be divided into negative pressure boiler and micro positive pressure boiler.
The economizer of condensing gas-fired boiler can be installed in the flue of the current CFB boiler, to recovery the energy from the high-temperature flue gas, in order to reduce the fuel consumption. Also, the economizer helps to absorb the air pollutants such as the NOx and sulfur dioxide.
The installation contents of boiler body pipeline are as follows:
1) Connection between water supply console and economizer header;
2) Connection between economizer and inlet pipe from economizer outlet to drum;
3) Connection between the main pipe and branch pipe of the drum drop and each lower header of the water wall;
4) Connection of steam guide pipe between each water wall header and steam drum;
5) Connection of superheated steam pipe between outlet header of low-temperature superheater...
The burner of natural gas boiler refers to the burner for gas-fired boiler. Gas burners are divided into natural gas burners, urban gas burners, LPG burners and methane burners. The burner of natural gas boiler is just one kind of burner.
A 10 tph boiler does not mean that the dead weight of the boiler is 10 tons. The ton of the 10 tph boiler is the heat load unit of the boiler, which is used in engineering, indicating that the rated evaporation capacity of the boiler is 10 t/h.
The type and parameters of coal-fired boilers are the direct factors affecting the cost of a small coal-fired boiler. For example, rated capacity, rated steam pressure, rated steam temperature, feed water temperature, etc. With different parameters, the more requirements, the higher the price.
