Bulk Hot Water Boiler

DHL29-1.6 / 130 / 70-AII bulk hot water boiler is a single-drum horizontal chain-grate boiler, in Π-shaped structure and installed indoor. This boiler can be used as a large centralized steam boiler 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 hearthparts and the forced circulation of the convection heating area. In thewater system, returned water enters in the drum and the down comerfalls to the cabinet of the water-cooling wall from the outer boiler, andthen reaches the drum. It is deviated from the top of the drum to theceiling pipe, and the coal economizer. The hot water can be deviatedfrom the exit of the coal economizer2) Burning method of coal scuttle veering chain-grate3) High and large hearth to improve the coal burning conditions. Thisboiler is with front and back arches4) Air pre-heater (trB=153oC) to accelerate the ignition and burning ofthe coal5) This boiler feeds the wind from two sides in sectionsTechnical parameters: 1) Rated heat efficiency: 29mW2) Boiler hot water flow: 410.5MT/h3) Boiler discharge pressure: 1.6MPa 4) Boiler rated exit/ inlet water temperature: 130oC / 70oC 5) Fuel features: grade II coala) Heat: 17,693kJ/kgb) Volatilization: 28.48% 6) Dimensions:a) Distance of the central lines between the left and the rightjambs: 5,820mmb) Max. width (podium included): 10600mmStructure: 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.
