Saw dust steam boiler as a kind of high efficiency energy saving and environmental protection products, equipped with drum induced draft fan for mechanical ventilation. And equipped with screw slag machine to achieve mechanical slag, complete control monitoring instruments, safe and reliable boiler operation. The front wall of the series of biomass fired boiler is arranged with secondary air, controlled by the valve, put into use when burning sawdust fuel, strengthen the combustion, fuel fully burned out, improve the combustion efficiency. 4 tons of steam boiler thermal efficiency up to 85%, and long service life, is a high efficiency energy saving environmental protection products. The above is for you to introduce 4 tons of sawdust steam boiler, more boiler product problems and quotation information can call, we will serve you wholeheartedly!
SZL series biomass boilers effectively reduce the consumption of energy, reduce the emissions of carbon dioxide, sulfur dioxide and nitrogen oxides, improve the environment. SZL series steam boiler operation environmental protection, fuel saving, automatic feeding, slag, boiler automatic operation, can automatically adjust the amount of fuel according to the load change, stable steam output. The boiler is the boiler that the society advocates to use, the market will focus on vigorously advocate biological steam boiler and boiler combustion technology. The boiler fuel uses biomass forming solid fuel. The water wall on both sides of furnace adopts membrane type water wall structure. Before and after the furnace wall water-cooled wall tube extends down to the upper part of the grate to form a front and rear arch, which not only increases the sealing performance of the boiler, but also increases the furnace volume and heating surface, while strengthening the strength of the rear arch.
Saw dust steam boiler furnace for burning chamber, convection bundle, tail economizer. The flue gas enters the tail flue through the furnace, the burning chamber, the convection tube bundle and the economizer, and is discharged into the atmosphere through the dust collector, induced draft fan and chimney. The front wall of this series of boiler products is arranged with secondary air, controlled by the valve, which is put into use when burning biomass fuel to strengthen the combustion, so that the fuel is fully burned out and improve the combustion efficiency. A higher feed port is used to meet the demand for biomass fuel.
Steam boiler in the structural design, compared with the traditional boiler furnace space is larger, at the same time the layout of a very reasonable secondary air, is conducive to the biomass fuel combustion of a large number of volatile matter precipitated out of the full combustion. Boiler feeding, combustion, slag removal, water supply, ignition can adopt automatic control, operation is very convenient. The boiler is equipped with automatic ash cleaning device, which can remove the ash accumulated on the boiler heating surface in time to ensure the efficient and stable operation of the boiler. The rear of the boiler is arranged with an energy saver, and the air preheater can also be arranged according to the user’s needs.
The upper and lower drum of biomass fired steam boiler are respectively provided with manhole device, one before and after the upper drum, and one lower drum. A hand hole device is provided at both ends of the left, right and front collecting boxes. It is convenient for boiler inspection and maintenance, and also provides great convenience for boiler cleaning after boiler shutdown. Saw dust steam boiler combustion equipment adopts two sides of uniform air pipe isobaric compartment ventilation structure. Segmented air supply, uniform air supply, convenient adjustment. Make the excess air coefficient of furnace not higher than 1.5. In order to prevent the grate from running stuck and slag accumulation at the back of the grate, the eagle iron (slag stopper) on the original grate is removed, so that the coal ash slag smoothly falls onto the slag machine and is discharged out of the furnace, improving the reliability of the boiler operation.
