Vertical steam coal fired hot water fired boiler for sale introduce vertical steam boiler Products: vertical steam boiler, all kinds of domestic furnaces comprehensive technical improvements, absorb the international advanced technology and the introduction of the new generation of horizontal fuel (gas) boilers, the product has been designed applied for the patent, the boiler head boiler shell, boiler shell, U-rings, furnace, furnace head, transverse pipes, tubes cupola. Combustion boiler using conventional techniques, from the media into the door hole, in the upper combustion grate, the flue gas was washed repeatedly laterally staggered in the cross-pipe furnace, in the flue gas containing fine dust particles and carbon black during the rise , multilayered tube is blocked, reducing the speed of movement, again falls on the combustion grate, burn the fumes into the atmosphere through the chimney. Performance: the boiler furnace grate rests within an upper portion of the U-shaped scraps, the direct flame furnace, and flushing mounted within curved tube furnace; vertical bent tube boiler structural features are: furnace interior curved inner pipe, increase radiation heating area. However, due to large water-cooling degree furnace, the furnace temperature reduced accordingly, therefore, generally suitable for burning high quality coal. The increase in the furnace masonry bricks, to maintain a high temperature furnace burn less coal. Better water circulation, where the site has been washed flue gas cooling water, the whole structure, good elasticity. Features: use of double grate combustion section of the combustion chamber, heating up, fast boosting of unburnt gas through the secondary combustion, functions as combustion, smoke, dust effect. Bending the upper furnace tube arrangement convection heating region, disposed in the lower furnace grate tubes and radiation heating furnace area, structure of the furnace and the flue gas flow, reasonable layout, good heat transfer, the boiler reasonable design, simple structure operation, easy maintenance, small footprint, less investment in infrastructure, the company is one of small enterprises with steam, heating and other equipment ideal.

Condensing gas coal fired hot water fired boiler for sale with coal-fired boilers What are the differences? Some may have which is not very clear to distinguish condensing gas boiler with coal-fired boilers, here we look at their specific differences, 1. The circulating fluidized bed combustion coal-fired boilers are coal by crushing equipment , by the belt into the coal bin, by using multicast coal stoker wind, thrown into the furnace; circulating ash by heating, fluidized combustion process. After coal to gas and coke oven gas and purge gas mixed together by the four burners directly injected into the combustor. 2. Combustion of Coal is mainly composed of water and ash content and the elements C, H, O, N, S etc., the heat released by combustion of coal to produce SO2, SO3, NOx ash and moisture, and SO2, SO3, NOx from the flue gas into the atmosphere, polluting the environment, cause harm to humans. And the main component of coke oven gas and purge gas are CO and H2, after combustion, produce mainly CO2 and H2O, SO2 emissions from coal-fired boilers is relatively gas boiler, SO3, NOx is much less. 3. Ventilation general negative pressure combustion coal burning boiler, a combustion process with the base by the induced draft fan and the blower mating fit together to complete coal combustion process, requires a lot of air and the furnace wall due to the leakage of flue excess air ratio of up to between 2.1-2.5. Micro-condensing gas boiler combustion positive or slightly negative pressure, a small amount of wind required, air is preferably premixed with the gas within the combustor. No leakage factor positive pressure combustion furnace flue wall and running flue outlet air coefficient can be 1.05-1.2.4 fuel combustion safety explosion-fired boilers, furnace explosion hazard unlikely to occur. The condensing gas boilers in the explosive concentration limits encountered fire will explode. More dangerous. The boiler control due to coal fired boiler, material thickness, amount of the blowing, the amount of the wind, the wind mixture ratio of coal and other reasons, to be automatically adjusted according to load difficult boiler operating parameters. And condensing gas boiler is less impact on the factors may be adjusted according to the size of the burner valve load, easy to achieve automatic control.

Most food processing facilities have industrial steam coal fired hot water fired boiler for sales or hot water boilers for generating steam or hot water for processing, cooking, or sanitation. Coal, fuel oil, and natural gas are the major fossil fuels used by food industry boilers.
