What is the Coal-fired boiler ?
Coal-fired boiler (The fuel is coal-fired boiler) Coal-fired boiler refers to the coal burned as fuel. After the heat of coal is converted, steam or hot water is generated. However, not all the heat is effectively converted, and some reactive power is consumed. Therefore, there is an efficiency p...Read more -
Boiler Cleaning
NECESSITY After the boiler has been running for a long time, it is inevitable that there will be scale and rust problems. The appearance of these problems, due to the generation of scale, makes the heat transfer worse, and the boiler efficiency is reduced. Therefore, it is difficult to reach the...Read more -
Boiler blowdown
Before the blowdown, the boiler water level is at the normal high water level, and the boiler pressure is 0.1-0.2MPA. According to the principle of “draining frequently, discharging less, and discharging evenly” (at least once a day), it is carried out shortly and intermittently, that...Read more -
Daily boiler maintenance
1. Pressure gauges, water level gauges (see the picture on the right), safety valves, sewage devices, water supply valves, steam valves, etc., check whether their performance meets the requirements, and whether other valves are in good switching state. 2. Automatic control device system, includin...Read more -
Boiler fouling and corrosion Solve
(1) If the boiler scales up during operation, it will firstly affect the heat transfer seriously. Since the thermal conductivity of scale is only one tenth of that of steel, when the inner surface of the boiler is scaled, the heat generated by fuel combustion cannot be very good. The ground i...Read more -
Boiler Common accidents and causes
(1) Incomplete combustion The fuel composition is too heavy to cause incomplete fuel combustion, causing combustibles to accumulate on the heating surface of GAH. Residues, cracking residues, and residual C4 fuels are purchased outside the boiler. They have heavier components, higher viscosity,...Read more -
Boiler Precautions
Precautions 1. When the boiler leaves the factory, it should be accompanied by “design documents required by safety technical specifications, product quality certificates, safety and maintenance instructions, and supervision and inspection certificates (safety performance supervision and in...Read more -
Boiler Safety Common Sense
Medium heat boiler is a high-temperature, high-pressure thermal energy equipment. It is one of the special equipment. It is widely used in government agencies, enterprises and all walks of life. It is a dangerous and special equipment. Once an accident occurs, which involves public safety, it w...Read more
