6MT Doppelzylinder montiert Hose Steam Boiler

Specifications: 1) Actual evaporation: 6MT/h 2) Pressure: 1.25MPa 3) Saturated steam temperature: 194oC 4) Water supply temperature: 60oC 5) Tested thermal efficiency: 81.12% 6) Outer size (L x W x H): 8.0 x 3.6 x 6.15m7) Fuel category: soft coal II The boiler is with a dual cylinder longitudinal structure and natural cycle methods consisting of the upper components with the dominant main parts. The lower components are primarily the combustion equipment. The two main parts can be instantly installed and manufactured.The boiler housing is with dense water exhaust cooling wall around the hearth. Partition is mounted at the back of the hearth in front of the convection check and forms the combustion ash room. Convection check is mounted at the back of the combustion ash room. The smoke flows into the first and the second checks through the combustion ash room and exhausts into the chimney through the coal saver and dust catcher.Structure: 1) Upper and lower cylinder diameter: φ 900mm 2) Cylinder central distance: 2,300mm 3) Left-right cabinet: φ219mm 4) Level central distance: 2,340mm 5) Hearth water cooling wall pitch: 53mm 6) Convection check distance: 90 x 120mm 7) The side wall is connected by 4 descending tubes leaded from the uppercylinder 8) There are 4 φ108 x 4.5 descending tubes at each side of the lowercylinder connected with the concentration cabinets 9) The boiler check and the water cooling wall are welded and connectedwith the upper and lower cylinders Combustion equipment: 1) Light chain-grate stoker 2) Width: 1,600mm 3) Effective area: 7.78m2 4) Six independent wind storage cabinets 5) Dual-side air inlet ash door 6) Brick boiler arc 7) Front water cooling arc and level angle are 30o 8) Outlet height: 1,013mm 9) Back arc outlet height: 764mm 10) Front-back arc coverage rates are 21% and 46.5% 11) The block wall is mounted at the upper outlet of the front arc toincrease the combustion room temperature and smoke flow Design features: 1) After extensive selection, the vertical hose boiler is easily defined andsymmetrical facilitating manufacture and maintenance. It is with compactsize and low metallic consumption, great water capacity and largeconvection heat transfer coefficient 2) To reduce the boiler wall weight, the side water cooling wall pitch isdensely structured and gets rid of the fire-bricks. Burial boiler wallincreases the air-tightness 3) Back arc and outlet block wall of the hearth are brick structured toincrease the temperature in addition to expanding the fuel application 4) Manhole is not installed in the combustion ash room. Smoke flow speedmay be increased appropriately, because the sole is mounted to exhaustthe ash to the lower grate 5) Front wall water cooling wall and descending tube are mounted toincrease the rigidity of the upper part 6) An aisle is reserved at the two sides of the convection check to reducedead corners and to facilitate maintenance 7) A hidden door is reserved at the back of the left side of thesecond convection check. If necessary, the aisle can be reached throughthe hidden door 8) Compressed shell, stylish design 9) Step-less motor and shift of the grates are necessary for the automaticcombustion 10) Equipped with multifunctional meter control panel; the inspectiondisplay meter, the water supply automatic control panel, and the coalcombustion control panel are for manipulating rotating speed on theoperation table 11) Thermal data determination: subject to the determination of NationalIndustrial Boiler Product Quality Inspection Center, the heated surfaceof the boiler is with reasonable configuration and large overloadcapacity of more than 10%. The average efficiency is 81.12%
