Coal fired boilers include coal fired hot water boilers, coal fired steam boilers and coal fired thermal oil boiler and so on. As the name implies, a coal-fired boiler is one whose fuel is coal. The coal fired boilers manufacturing refers to the thermal power equipment that releases heat through burning coal in the furnace and heats water or other organic heat carriers to a certain temperature (or pressure).
The coal fired hot water boiler is densely covered with light pipe and water wall pipe on both sides of the furnace, and threaded smoke pipe is arranged in the pot barrel, three – return water – fire tube structure is arranged in the longitudinal direction of a single drum. So the design structure is reasonable and compact. The heating area is large, the flue gas flow is long, the heat transfer effect is good, the exhaust temperature is low, so the thermal efficiency is high, the operation cost is low, the use is more economical. This series hot water boilers widely used in factories, hotels, hospitals, office buildings, schools, bath centers, hotels, sheds, baths and other enterprises and public institutions, to meet the use of units bathing, domestic hot water and heating requirements.
Coal fired steam boiler three-way water and fire tube structure with longitudinal arrangement of a single pot barrel is adopted, and both sides of the furnace are densely covered with light pipes and water wall pipes. Design structure is reasonable and compact; The heating area is large, the flue gas flow is long, the heat transfer effect is good, the exhaust temperature is low, so the thermal efficiency is high, the operation cost is low, the use is more economical. The furnace body is equipped with gauges, safety valves, water level gauges and other instruments. The gauges show the pressure of the boiler to ensure safe and reliable operation of the boiler.
Coal fired thermal oil boiler uses coal, oil and gas as fuel and thermal oil as medium. It uses a circulating oil pump to force thermal oil to heat liquid in the furnace. After the heat energy is transferred to the thermal equipment through the pipe network, it is returned to the high temperature, low pressure and energy saving equipment of the thermal oil furnace. The heating surface of this series boiler adopts the compact disk tube, the heating surface is adequately arranged, the surface heat load is reduced, the thermal efficiency is high, the use is safer. The fuel is burned adiabatically in the combustion chamber, which makes it easier to ignite and burn more fully, thus improving the thermal efficiency of the boiler. Convenient installation, short installation cycle.
Coal fired boilers manufacturing air preheater is installed at the end of boiler flue to recover waste heat of flue gas and improve the temperature of combustion-supporting air. In order to improve the hot air temperature, the boiler with high parameter and large capacity often needs to make the air preheater and the energy saver to be arranged in cross stages.
