SZL series coal-fired steam boilers have the characteristics of low operating cost, which is mainly due to the relatively cheap coal and scientific structural design. Horizontal coal-fired boiler has scientific structure and reasonable design. The furnace in the boiler has a large heating area, so that the fuel can be fully burned in the furnace and the heat can be fully converted. Coal-fired steam boiler adopts fast loading design structure, boiler body is compact, does not occupy too much space, it is more convenient in transportation and installation.

Horizontal coal-fired boiler

SZL6-1.25-t assembled water tube boiler, using double drum longitudinal arrangement, combustion equipment with chain grate. Rated evaporation capacity of 6t/h. Rated steam pressure 1.25MPa, rated steam temperature 194℃, boiler design fuel biomass molding fuel. This series of boiler products have an energy saver in the tail. The flue gas enters the tail flue through the furnace, ember chamber, convection bundle and energy saver, and is discharged into the atmosphere through the dust collector, induced draft fan and chimney.

The boiler is divided into two parts factory, upper parts including boiler body, upper steel frame and upper furnace wall, lower parts including hopper, chain grate, lower furnace wall and internal ventilation duct. In addition to the front and rear arch pipes and their connecting pipes, part of the brick wall was built on site. Other parts are assembled factory, tail economizer and smoke duct with the furnace matching factory. The water cooling system of coal-fired boiler includes front water wall, side water wall, convection tube bundle, upper and lower drum, down pipe and collector box. Horizontal coal-fired boiler have high efficiency, strong overload capacity and wide adaptability to coal species.

SZL type steam boiler furnace on both sides of the wall water wall membrane 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. After the furnace for the combustion chamber, convection bundle, tail coal economizer (or air preheater). The flue gas enters the tail flue through the furnace, the burning chamber, the convection tube bundle, the economizer (or the air preheater), and is discharged into the atmosphere through the dust collector, induced draft fan and chimney.

SZL type steam boiler

Horizontal coal-fired boiler is equipped with horizontal cyclone combustion chamber, which has remarkable effect on improving thermal efficiency and reducing smoke emission concentration. The flue gas emission concentration of boiler is less than 100 mg/standard meter 3, the blackness of flue gas is lower than Lingermann 1, which meets the requirements of class A environmental protection area. Coal fired steam boiler tail separately arranged cast iron economizer, grate using warehouse ventilation structure, flexible adjustment, according to the needs of users can choose stratified coal feeding device, safe and reliable operation, welcomed by users, investment, quick effect, wide adaptability of fuel.
