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 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...
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...
Different users have different requirements for boiler configuration. For example, some users need NOx emission less than 30mg/Nm3, and some users only need it less than 80mg/Nm3. The better auxiliary equipment configuration is used, the price of boiler will naturally rise.
Different users have different requirements for the configuration of the whole boiler system, and the brand and quantity of auxiliary machines also affect the price. The better the brand, the more expensive the price. For ex...
The boiler in the bathhouse provides hot water for bathing and heating, and it is an essential product in bathhouses. Generally, it is hot water boiler. With the elimination and banning of coal-fired boilers, many users choose energy-saving and environment-friendly gas-fired boilers. Then how much is a suitable gas-fired boiler?
First of all, we have to determine the boiler plan. Bathhouses mainly need to supply hot water and winter heating all the year round. There are two main options: one se...
Water and electricity are not available;
Circulating water pump is not running;
Water flow switch is different;
The 200V 380V power supply is not connected;
The valve is not opened;
The controller switch is set incorrectly;
There is a problem with the controller circuit;
There is something wrong with the programmer;
Leak detection has not been checked;
Air pressure switch impassability;
Air pressure switch 1-3 impassability;
Overtemperature protection and combustion heat protection;...
The boiler drum is connected with downcomer and water wall to form a natural circulation loop. At the same time, the boiler drum receives the feed water from the economizer and delivers saturated steam to the superheater. Therefore, the boiler drum is the connecting hub of the three processes of heating, evaporation and overheating in the boiler.
