Question details (Performance) :
1. The vibrating coal grate stops running totally or intermittently.
2. The current of vibrating coal grate motor rises abnormally.
3. The safety clutch of transmission machine of grate or safety pin is broken.
Answer: cause of the problem:
Boiler’s vibrating coal grate is a rotating combustion equipment, due to the bad working conditions, stuck stalling is easily happened and grate failure happens in daily application and ...
It can be found that there are the following differences between vertical coal-fired hot water boiler and horizontal coal-fired hot water boiler by analyzing the structural diagram of vertical coal-fired hot water boiler:
The heat transfer of vertical coal-fired hot water boiler and horizontal coal-fired hot water boiler
The exhaust gas flow produced by the vertical coal-fired hot water boiler flows vertically to the heating surface from top to bottom, and the exhaust gas temperatu...
Coal-fired boiler economizer, as its name implies, is a boiler device to save energy. The structure of coal-fired boiler economizer is relatively simple, which is mainly composed of all stainless steel 304 frame and stainless steel spiral finned tubes, all of which are arranged in a certain order.
According to the power, size and price of the boiler, the boiler economizer adopts different materials such as stainless steel and ND steel. According to the medium, coal-fired boiler economizer is ma...
As a new mature high-efficiency and low-pollution clean coal technology, circulating fluidized bed combustion (CFBC) technology has many advantages that other combustion methods do not have. Circulating fluidized bed combustion is low-temperature combustion, so the NOx emission is much lower than that of pulverized coal furnace, only 200ppm.
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.
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?
Hot-water boiler is a kind of thermal equipment that uses the heat energy released by fuel combustion or other heat energy (such as electric energy, solar energy, etc.) to heat water to the rated temperature. According to different fuels, hot water boilers can be divided into gas-fired hot water boilers, oil-fired hot water boilers, biomass-fired hot water boilers, and coal-fired hot water boilers. How to choose hot water boiler? We will focus on the heating, pressure and thermal efficiency of hot water boiler.
