Chain grate has certain selectivity for coal types, and soft coal with volatile content above 15%, ash melting point above 1250℃, moderate particle size and calorific value above 18800~21000kJ/kg is more suitable.
Generally, small gas-fired hot water boilers are between 0.7 MW and 14 MW, and the output of boilers is different, so the prices are different. Different pressures require different techniques, materials and pressures. The higher the pressure, the higher the price.
A 10 tph boiler does not mean that the dead weight of the boiler is 10 tons. The ton of the 10 tph boiler is the heat load unit of the boiler, which is used in engineering, indicating that the rated evaporation capacity of the boiler is 10 t/h.
Because a certain amount of air is usually dissolved in water, with the increase of temperature, the solubility of air decreases, and the gas is gradually separates from the water in the process of water circulation, and gradually gathers together to form large bubbles and even gas columns. Gas is often produced due to the water supplement, so the boiler exhaust valve must be used to avoid damage to the system.
The type and parameters of coal-fired boilers are the direct factors affecting the cost of a small coal-fired boiler. For example, rated capacity, rated steam pressure, rated steam temperature, feed water temperature, etc. With different parameters, the more requirements, the higher the price.
Under the strict control of the policy, a wave of new energy boiler fuels and environmental protection transformation of combustion equipment has been launched in various coal-forbidden areas, which has brought new opportunities to the new energy boiler fuel market. What are the new energy boiler fuels?
With the rapid development of economy, the demand for industrial boilers in modern enterprises is increasing. Because of the particularity and complexity of industrial boilers, we must understand the problems clearly before purchasing. According to the question "what is the main function of boiler superheater", ZOZEN Boiler will answer the doubts first.
As an important heat energy supply equipment, industrial boiler is widely used in food, electronics, paper making, building materials, textiles and chemical industries. According to the medium, industrial boilers can be divided into steam boilers, hot water boilers and thermal oil heaters. In order to solve the problem "How many tons are the rated thermal power of 42 MW of industrial boiler?" First of all, we need to know the basic knowledge of rated thermal power and unit ton.
