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...
Heat exchange station and gas boiler room are completely different individuals. Gas-fired boiler room is a place where water (or other medium) is heated with fuel to certain parameters. Gas-fired boiler room is a place where heat source is produced. Its main equipment includes boiler, blower, induced draft fan, circulating pump, and various auxiliary equipment (water treatment), among which boiler is the main part.
The purpose of the heat exchange station is to convert the high-temperature hot ...
The principle of boiler economizer is that the flue gas from the boiler tail enters the boiler economizer, and the water in the boiler economizer absorbs the temperature in the flue gas through the finned tube and then returns to the boiler, which is equivalent to raising the boiler feed water temperature and reducing the energy consumption when the boiler output is certain.
Boiler economizer is generally installed at the tail of boiler flue. Due to the different principles and boiler equipment...
The boiler needs to blow off every day, and it is advisable to reduce the blowdown to below the boiler water level every time.
The boiler water level meter can record the boiler water level in detail, and the water level has a great influence on the boiler, so we should ensure that the boiler water level is within the normal range.
When the gas-fired boiler is running, there will be pressure inside, which can provide sufficient power for all kinds of production equipment. However, if the press...
Modular gas-fired boiler, according to the user's load and design needs, combines several independently operating module units into an integral boiler. By monitoring and calculating the changes of indoor and outdoor temperature and temperature of supply and return water, the computer automatic control system can control each level of modules, automatically adjust the number of modules to start and stop, make the output heat always match the actual required heat load, and ensure that each module ...
1. Water leakage on the inner wall: Water leakage on the inner wall can be divided into three types: boiler leakage, water wall leakage and downcomer leakage. If the leakage holes of boiler barrel and water wall are relatively small, it is ok to use steel with the same steel grade for patching and flaw detection. If the downcomer is leaking, it needs to be replaced.
2. The hand hole leaks: you can re-install it from another angle to see if the hand hole cover is deformed. If it is deformed, you...
What is a hot water boiler? Hot water boiler is a boiler that produces hot water. It refers to a kind of thermal equipment that uses the thermal energy released by fuel combustion or other thermal energy (such as electric energy, solar energy, etc.) to heat water to the rated temperature. Hot water boiler is widely used in all aspects of heating.
In the process of hot water boiler boosting, the essence of controlling the boosting speed is to control the heating speed, which requires that the te...
1. The defective parts in the last inspection.
2. Whether there are cracks and corrosion on the inner and outer surfaces of boiler pressure components, especially on openings, welds, edges and so on.
3. Whether the pipe wall is worn or corroded.
4. Whether there is any crack, fracture or corrosion at the brace of the boiler and the joint with the pulled element.
5. Whether the expansion port is tight, and whether there is annular crack in the expanded part of the pipe end.
6. Whether the ri...
