The air oxygen content's effect on the boiler is mainly reflected by the effect on the blowing rate. Boiler will have typical phenomena if the blowing rate is high or low.
The coal-fired boiler has always been one of the important boiler types in the industrial production and its operating costs and capacity play an important role in the enterprise operation.
1. Scale Prevention: Phosphates are used in boiler water treatment primarily to prevent the formation of scale. Scale is a deposit that forms when boiler water becomes oversaturated with dissolved minerals. When these minerals precipitate out of the water, they can coat the inside of the boiler and insulate it, leading to decreased heat transfer efficiency and increased fuel consumption. By maintaining the appropriate phosphate levels, these minerals can be kept in a soluble form, reducing their...
The flue gas chamber, also known as the combustion chamber or firebox, is an essential component of an industrial boiler. Its primary function is to provide a space where fuel is burned, and heat is generated.
During the combustion process, fuel is burned in the flue gas chamber, producing high-temperature flue gases and heat. The heat is then transferred to the water or steam in the boiler tubes, generating steam or hot water for industrial processes or heating applications.
The flue gas cham...
Proper shutdown procedures are crucial for ensuring the safe and efficient operation of a coal-fired steam boiler. The following steps should be followed when shutting down a coal-fired steam boiler:
1. Reduce the load: Before shutting down the boiler, the load should be reduced to its minimum level. This will help to prevent sudden drops in pressure and temperature, which could cause damage to the boiler and its components.
2. Shut off the fuel supply: The fuel supply to the boiler should be ...
The primary air fan of the boiler consists of motor, impeller, casing, air inlet box, current collector, base, regulating control system, etc.
The working process of the primary air fan: Take the medium-speed coal mill and direct-fired pulverizing system as examples, the atmosphere enters the primary air fan and is divided into two paths after being boosted by the primary air fan. One path of the atmosphere enters the primary airpipe in front of the coal mill. The other path enters the air preh...
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...
