With this boiler the fuel-firing system is an integral part of the boiler and boiler design. A coal-feed device is fitted to which fuel may be delivered either mechanically by means of a screw conveyor from an overhead fuel bunker, or pneumatically from a coal storage area located at or below ground level.
Henan boiler, mainly produces industrial boilers, such as oil-fired boilers, gas boilers, coal-fired boilers, etc.. Through the integration of raw material molding, parts processing, finished product assembly, full-process production, vertical integration of the industrial chain.
A vertical spindle mill is also designed for pressurized and suction type requirements. Boiler designers use this type of mill for poor quality coal as this type of mill rejects foreign materials like stones and other high density materials. The power consumed by the mill per ton of coal ground is only two-thirds of the ball mills.
