14MW coal-fired hot water boiler body

 SZL14-1.25/115/70-All is a 14MW, that is, 20 tons hot water boiler, which is often used for central heating, such as heating in residential quarters, heating in office buildings, heating in large commercial supermarkets, public workshops in factories, vegetable and flower greenhouses Heating, etc. are inseparable from coal-fired hot water boilers.

Due to the serious pollution of coal-fired boilers below 10 steam tons, it is recommended that you purchase large-tonnage and large-capacity coal-fired boilers. If it is a hot water boiler with less than 10 steam tons, it is recommended to choose environmentally friendly and clean fuels, such as methanol boilers, natural gas boilers, biomass boilers, etc.

2. Szl14-1.25/115/70-All structural performance

1) szl14-1.25/115/70-All is mainly composed of upper and lower drums, convection tube bundles, water-cooled wall tubes, downcomers and headers. The upper and lower drums are arranged vertically. Continuously variable transmission drive. The boiler body consists of vertical upper and lower drums and convection tube bundles.

2) The upper drum of szl14-1.25/115/70-All is equipped with steam-water separation and continuous sewage discharge device; the lower drum is equipped with regular sewage discharge device to ensure the steam quality. Equipped with a continuous automatic water supply device to ensure the safe operation of the boiler, and an economizer is arranged at the tail of the boiler.

3) Extended grate

The length of the front and rear shafts of the grate is longer than that of domestic products of the same model, which prolongs the burning time of fuel in the furnace, makes the coal burn fully, reduces the carbon content of slag; increases the effective area of ​​the grate, and significantly enhances the overload capacity of the boiler.
