Product Description

Product Description

Coal-fired steam boilers burn coal to produce high-temperature combustion gases, which exchange heat with boiler water in the boiler, thus heating the water into high-temperature and high-pressure steam. The steam is then exported through the outlet pipe of the boiler to supply industrial production equipment or power plants that need heat energy.

FAQ

 

1. What is the basic working principle of coal-fired steam boilers?
A: Coal-fired steam boilers generate heat by burning coal, and this heat is transferred to the water in the boiler, causing it to evaporate and turn into steam. Steam can then be used in a variety of industrial and commercial applications such as heating, power generation, steam driven equipment, and more.

2. What are the main components of coal-fired steam boilers?
A: Coal-fired steam boiler is mainly composed of furnace body, combustion system, heating surface, safety accessories (such as safety valve, pressure gauge, water level gauge) and auxiliary equipment. The furnace body is the main part of the boiler, the combustion system is used for burning coal, and the heating surface is responsible for absorbing heat and producing steam.

3. What is the usual efficiency of coal-fired steam boilers?
A: The efficiency of coal-fired steam boilers varies depending on the boiler model, design, operating conditions and other factors, but the efficiency of a general large boiler is between 60% and 80%. Efficiency is affected by a number of factors, including combustion efficiency, heat loss (e.g. smoke loss, radiation loss, etc.), and the maintenance status of the boiler.

4. What is the function of the safety valve of the coal-fired steam boiler?
Answer: The safety valve is an important safety accessory of coal-fired steam boilers. When the pressure in the boiler exceeds the set value, the safety valve will automatically open to release excess steam to prevent the boiler from exploding due to overpressure and other safety accidents.

5. How to ensure the safe operation of coal-fired steam boilers?
A: To ensure the safe operation of coal-fired steam boilers, we need to do the following: regular inspection and maintenance of the boiler and its ancillary equipment; Strictly abide by operating procedures and safety regulations; Water pressure test and safety valve calibration of boiler are carried out regularly. Discover and deal with the abnormal situation in boiler operation in time; Ensure that the boiler room is well ventilated to prevent safety accidents such as gas poisoning.
