single drum 4 ton coal steam boiler for food industry

SZL coal fired chain greate single drum 4 ton coal steam boiler for food industry for sale

Coal fired boiler design features:

1.By adopting of double wings gas ducts, the fuel gas can go into the front gas tank easily, so the temperature of different front plates can be same. In this way, it can avoid the crackles happening in the plates.

2.Spiral tubes are installed in the drums, which can strengthen the heating transferring efficiency, at the same time, spiral tubes have the ability of dust removal, which can avoid the dust stratification in the tubes.

3.Both of the front and the back arches of the 10t/h series coal fired boiler design adopt mason work of water cool tubes wall structure, which can form permanent arches.

4.Separate adjustable wind chambers. Wind is feed from two sides. It adopts new type crank screw wind adjustment structure, so that the wind adjustment and ventilation cross section proportion is 100%, which can ensure the easy wind adjustment and make it symmetrically.

5.There is push-pull damper dust removal equipment. The damper adopt finish machining cast iron seal structure, thus the secondary combustion distortion and air leaking in the grate is effectively prevented.

Mixed biomass and coal fired single drum 4 ton coal steam boiler for food industry, what the hell it is? Literally, you can guess is that a kind of steam boiler which can burning biomass fuel and coal fuel at the same time. Bingo, you are right here. In ZG Boiler, our engineer can reform some old chain gate boilers on technology parts. As to national policy, governments encourage factories use biomass fuel, natural gas, etc those clean energy during their producing or manufacturing process. Here, according to the rich experience on boiler reforming, our ZG Boiler put new type mixed biomass and coal fired steam boiler into markets. This mixed biomass and coal fired steam boiler, is also a kind of chain grate boiler, DZL and SZL to choose for different consumers.

Inter-regional Pingdingshan Coal Industry Group Co., Ltd. by the Pingdingshan Shenma Group and two Chinese top 500 enterprises founded by restructuring, cross-industry, cross-ownership and transnational business of large state-owned energy and chemical group, under the People's Government of Henan Province , is the most complete variety of coking coal, thermal coal production base, has Asia's largest chemical production base in nylon. Carefully selected and comparison, fast boiler Pingmei cooperation with party has chosen to provide a 2 tons of steam electric single drum 4 ton coal steam boiler for food industry (WDR2.0-1.25-II) by a fast side.

Coal-fired single drum 4 ton coal steam boiler for food industry scale can cause harm and failure scale is the first coal-fired steam boilers, coal-fired steam boiler is the main cause of the accident, the danger main problems: wasting a lot of fuel: Because the thermal conductivity of the scale of only a few steel one tenth, so that the heating surface when the fouling of heat transfer will hindered, in order to maintain a coal-fired steam output, it is necessary to increase the temperature of the side of the fire, so that the external radiation and flue gas heat loss. Now can be used efficient and environmentally non-corrosive cleaning agent fired steam cleaning, expose the metal tube so that the device primaries, and to reduce biological fouling of algae because silt impact. While the peeling effect of iron on the iron oxide and ethylene, prolong the service life of coal-fired steam boilers, to reduce energy consumption and improve productivity. Fired steam after a long run, the inevitable emergence of scale, the problem of corrosion, scale coal-fired steam boiler formation is mainly due to the water with hardness components, high temperature, high pressure after continuously concentrated by evaporation, the coal-fired steam furnace with a series of physical, chemical, and finally heating surface to form a hard, dense scale, resulting in reduced heat transfer and the effect of corrosion under the scale factors, leads to a reduction endothermic coal-fired steam boiler waterwall furnace, burning coal steam boiler furnace exit temperature increases, the increase in the loss of coal-fired steam boilers. After scaling while reducing the heat transfer within the water wall, water wall tube wall temperature may lead to increased water wall lead to burst pipes, affect the safe operation of coal-fired steam boilers.
