Factors affecting the price of coal-fired boilers
In recent years, with the successive introduction of environmental protection policies, there have been many restrictions on the use of coal-fired boilers, but the fuel prices of environmentally friendly boilers such as biomass boilers and gas boilers are much higher than coal. China is the world’s largest coal-producing country. Its coal resources are extremely rich and distributed in all provinces and regions. Therefore, coal-fired boilers cannot be completely replaced. So in the case of the increasingly prominent contradiction between coal burning and environmental protection, environmentally friendly coal-fired boilers have become the first choice.
Factors affecting the price of coal-fired boilers
So what factors influence the price of environmentally friendly coal-fired boilers?
1. Models and parameters of coal-fired boilers, such as: rated evaporation, rated steam pressure, rated steam temperature, feed water temperature, etc
A. Rated evaporation:
Evaporation refers to the amount of evaporation produced per hour. The positive and nominal evaporation is generally between 1-75t / h. The output is different, and the price of coal-fired boilers is also different.
B. Rated steam pressure:
Different pressures require different process technologies, materials and stresses. The higher the steam pressure, the more expensive the price.
C. Rated steam temperature:
Steam temperature is a factor that affects the pressure. Generally, the higher the pressure, the higher the temperature. Therefore, the more technical and material requirements, the more expensive the price.
2. The different types of coal used also have an impact on the price of the boiler. According to the characteristics of various types of coal, such as different volatile matter, moisture, calorific value, etc., the size and position of the coal-fired boiler in the furnace, the size and position of the heating surface, and the combustion equipment (such as: chain grate, reciprocating grate, beam grate, etc.) Other aspects need to be adjusted accordingly.
3. Auxiliary equipment configuration of coal-fired boilers: Different users have different requirements for boiler configuration, and the amount of supporting equipment also affects the price. Zhongzheng Boiler can customize the feeding system, slag discharge system and tail flue gas treatment system for users.
4. Boiler auxiliary machinery brands used: There are many brands, and the prices vary greatly.
5. Manufacturing process of coal-fired boilers: The manufacturing process of the boiler determines the quality of the product and directly affects the factory price of the boiler, but from a long-term perspective, a high-quality boiler has lower maintenance costs and a longer service life. .
6. The coal-fired boilers are used in different regions and at different altitudes. The boiler auxiliary equipment specifications also need to be adjusted accordingly (such as blowers, induced draft fans, etc.), so it will also affect the price of the boiler.
7. Coal-fired boilers have a quick-install structure, an assembly structure, and a bulk structure. The selected boiler factory structure is different, and the corresponding installation cost will also be affected.
