25MT Double-Drum Steam Boiler

Technical parameters:1) Type: SZL25-1.25-AII double-drum assembled steam boiler2) Heating area: 1009m23) Heating efficiency: 80%4) Effective area of the chain-grate: 25.4m25) Applicable fuel: grade II soft coal6) The installed mainframe dimensions (L x W x H): 17 x 6 x 8.5m   7) Total metal weight: 108.911MT 8) Boiler layout method: indoor single-layer layout This boiler is with double-drum vertical laid structure as a natural cycle boiler. It is made of upper and lower parts. The boiler body and the hearth are for the upper part, and the burning equipment is the lower part. Boiler wall is the joining parts. Fire-proof concrete is used to cast the front and back arches. After connecting the gas circulation, pipe, meter, valve, air pre-heater and the coal economizer, it can be operated.Features:1) The boiler shape selection is generally considered that the vertically laid    water pipe can easily form clear interface, and it is in good symmetry. It    is convenient for manufacture, maintenance, and installation. The    ascending pipe and descending pipe of the water circulation structure    play the role of a suspending steel-frame. With compact structure, this    boiler is with large water capacity, reliable water circulation and full    contribution 2) According to boiler wall height, we install the water-cooling wall    differently. The hearth is installed in seal, and the outer pipe only needs    to be laid on boiler wall. The distance between the convection is 96,    and the outer pipe uses
