Detailed Product Description
DHL29-1.6 / 130 / 70-AII bulk hot water boiler is a single-drum horizontal chain-grate boiler and installed indoor. This boiler can be used as a large centralized steamboiler of heat supplying station and heat-load peak adjusting set of heat and power station.

Features:  
1) Water circulation is through the natural circulation piling of the hearth
   parts and the forced circulation of the convection heating area. In the
   water system, returned water enters in the drum and the down comer
   falls to the cabinet of the water-cooling wall from the outer boiler, and
   then reaches the drum. It is deviated from the top of the drum to the
   ceiling pipe, and the coal economizer. The hot water can be deviated
   from the exit of the coal economizer
2) Burning method of coal scuttle veering chain-grate
3) High and large hearth to improve the coal burning conditions. This
   boiler is with front and back arches
4) Air pre-heater (trB=153oC) to accelerate the ignition and burning of
   the coal
5) This boiler feeds the wind from two sides in sections

Technical parameters:
1) Rated heat efficiency: 29mW                
2) Boiler hot water flow: 410.5MT/h                
3) Boiler discharge pressure: 1.6MPa
4) Boiler rated exit/ inlet water temperature: 130oC / 70oC
5) Fuel features: grade II coal                    
   a) Heat: 17,693kJ/kg
   b) Volatilization: 28.48%
6) Dimensions:
   a) Distance of the central lines between the left and the right
       jambs: 5,820mm  
   b) Max. width (podium included): 10600mm

Structure: the large parts of the boiler consist of heating areas, metal parts and burning system parts. The heating area consists of drum, water-cooling wall system, roof tube, coal economizer and air pre-heater. The burning system consists of coal scuttle, chain-grate, chain-grate gearing device, and slagging device. The metal structure consists of pillar, beam, podium ladder, ceiling plate and protection plate
