Horizontal Fixed Grate Coal Hot-water Boiler

1、 Product features and scope of application:
The design and manufacture of wnhg series horizontal atmospheric pressure coal-fired (diesel) hot water boilers produced by our company are strictly in accordance with the requirements of "Regulations on safety supervision of small and atmospheric pressure hot water boilers" and JB / t7985-2002 "technical conditions for small and atmospheric pressure hot water boilers" and "technical conditions for manufacturing shell boilers". The thermal efficiency of this horizontal atmospheric pressure coal-fired (diesel) hot water boiler is above 77%, which is completely higher than the requirements in the general technical conditions for industrial boilers issued by the state. Wnhg series horizontal atmospheric pressure coal-fired (diesel) hot water boiler is a whole quick installation factory. After it is transported to the use site, it only needs to install valves and instruments, blowers, induced draft fans, smoke and air pipes, dust collectors and water circuits Running on the spot, it has the advantages of fast start, fast fire making, large heating area, long flue gas flow, good heat transfer effect, low exhaust gas temperature, high thermal efficiency, low operation cost and more economical use;
Boiler structure: three return water fire tube structure with longitudinal arrangement of single drum is adopted. Smooth tube water wall tubes are densely distributed on both sides of the furnace, which is reasonable and compact. Cast iron grate is adopted, which is durable and has long service life. Combustible fuels such as wood are fully burned in the furnace, and the generated flame will enter the atmospheric coal-fired heat through the flue gas channel of the middle furnace wall The back part of the water boiler body turns to the front smoke box from the burn out chambers on both sides, then turns back to the tube bundle in the boiler from the front smoke box, finally enters the dust collector through the rear smoke box, and is pumped by the induced draft fan through the flue to the chimney and finally discharged to the atmosphere. (this type of boiler is manual coal feeding type); since the atmospheric hot water boiler operates without pressure, it can be installed anywhere without the limitation of many levels of annual supervision and inspection procedures. It is suitable for bathing, domestic hot water and heating requirements. It effectively solves the dual purposes of heating and bathing. In addition, the horizontal coal-fired atmospheric hot water boiler is recycled by hot water circulating pump The purpose of bathing can be achieved by heating the hot water in the environment-friendly incubator. If the hot water circulating pump is used to heat the heating pipe, the requirements of people's heating can be achieved. If the horizontal coal-fired atmospheric pressure hot water boiler and hot water circulating pump are used together with the heat exchanger, the dual functions of heating and bathing can be realized.
