How Does Your Coal Fired Boiler For Sale Work?
The coal fired boiler working principle is easy to understand. It is just a series of operations leading to efficient steam generation. For extensive understanding, let’s break down the coal fired boiler working into easy steps:
Step 1: Coal Feeding
The Yongxing boilers use coal as fuel, so they have installed automatic coal feeders for convenience. It means that once you fill the coal feeder, it will automatically feed the coal as per the furnace’s requirement. The automatic coal feed system use gears to transfer the coal from the tank to the boilers’ furnace.
Step 2: Combustion Process
The combustion process occurs in the large furnace area of the fired coal boilers for sale. The furnace area is designed larger to have a space for complete and efficient combustion. When the coal is fed to the boilers’ furnace, the preheated air ignites it, and thus heat is produced.
The highly efficient forced draft fans are installed to push the air into the furnace for igniting the coal. Some air portion of the forced draft fan flows through the air preheater to transfer the exhaust gases heat to the boilers’ furnace.
The whole idea of the air preheater is to use the heat of exhaust gases in order to reduce the furnace’s heat load. Besides raising the furnace’s temperature, the air preheater also helps reduce moisture and produce a cleaner burn.
Step 3: Steam Generation
The fuel combustion in fired coil boilers generates the heat used for converting water into steam. The furnace’s heat is transferred to the liquid and then passes through the preheater. The saturated steam generated might still have moisture and can do corrosive damage to the system. Therefore, the saturated steam is routed back for further heating. Hence, it converts into dry superheated steam, which can be used for different purposes.
Step 4: Waste Removal
When the combustion process is completed, the waste flue gases are routed out. Lastly, the process required is ash removal. The Yongxing boilers use the latest technology for fast ash removal. Its boilers come with slag exit holes where the waste ash is exited out from the system.
