The overall design and structure of the coal-fired steam boiler is reasonable, and the large furnace is easy to fully burn the fuel. Industrial coal fired boiler according to the combustion characteristics of the fuel, the furnace arch is designed reasonably to improve the burning of the fuel and eliminate the black smoke. The use of high strength large grate, suitable for the transport of biomass fuel combustion, for large grate with a roller device, improve the grate safety, convenient combustion adjustment.
The series of coal fired boilers use unique high feeding and pull feeding device to adapt to the fuel characteristics and prevent the ignition before the fire. The unique secondary feeding device blows the flame back, prevents the flame from jumping into the hopper, and strengthens the oxygen supply, promotes the combustion, and prevents the black smoke generation. Reasonable arrangement of heating surface and combustion device, boiler thermal efficiency is 4~5 percentage points higher than the standard.
Industrial coal fired boiler are designed with reasonable smoke speed, so that the heating surface does not accumulate dust and wear. The heating surface of the boiler can maintain high efficiency, full load and safe operation for a long time without soot blowing. Boiler all independent loop design, for the hot water boiler also uses reasonable ejector circulation, heating surface loop medium flow rate higher than the standard requirements. Inertial separation of smoke and dust at furnace outlet can effectively reduce dust concentration of exhaust smoke and reduce wear on rear heating surface.
The structure of this series steam boiler is compact, the installation volume is smaller than that of other types of boilers with the same capacity, and the installation cycle is shortened and the cost of boiler room is reduced. Large volume of water, conducive to power failure protection, strong ability to adapt to load changes. At the same time, the product also adopts the way of three return combustion, with high thermal efficiency, fast steam production, long service life and other advantages.
Coal fired steam boiler using PLC controller, can modify a variety of control algorithm program. Thus to complete the temperature, pressure, flow and other analog quantities of closed-loop control. Widely used in schools, textile mills, clothing factories, printing and dyeing factories, restaurants, food factories, beverage factories, bean products factory, meat products factory, cannery, winery, pharmaceutical factory, packaging factory, building materials factory, coating factory, swimming pool and other enterprises and institutions.
The boiler adopts chain grate, which has good energy saving effect and reduces the load of installation and maintenance of grate. Industrial coal fired boiler reasonable grate air distribution is conducive to fuel burning and improve the efficiency of the whole machine. Reasonable boiler air distribution, increase the grate effective area, improve the burning out degree of fuel. Products with pressure, temperature, water level and other multiple interlock safety control. Product control system is automatic, high degree of mechanization, simple and convenient operation. Whole quick installation factory, easy to install. Zozen Boilers specialize in producing various types of boiler, welcome to consult and purchase.
