图1示90吨/时,70公斤/厘米~2,455℃,燃用天然气的(用油作备用)微正压锅炉的炉墙结构。整个炉膛按承受510。毫米水柱的压力设计。用点焊在管子外壁上的钢丝网4来支持可浇灌的耐火材料1,外面再用相互焊接,并与水平槽钢横撑焊牢的10号钢板构成将整个锅炉包围起来的墙皮。钢板用焊在管子上的夹子锚定。其上为绝缘板,块,毡,最外面为耐风雨的绝缘层。无外墙皮。所有人孔均系圆形,锅炉运行时锁上封牢,并在炉膛压力作用下保持严密。送风机出口压力为330毫米水柱,炉膛压力140毫米水柱。
Figure 1 shows 90 t / h, 70 kg / cm ~ 2,455 ℃, fired natural gas (oil reserve) slightly positive pressure boiler furnace wall structure. Press the whole hearth 510. Mm water column pressure design. The water-repellent refractory material 1 is supported by a wire mesh 4 welded on the outer wall of the pipe, and the outer skin is welded to the outer wall of the boiler by the No. 10 steel plate which is welded to the horizontal channel brace. Steel plates are anchored by clips on the pipe. On the insulation board, block, felt, the outermost windproof insulation. No exterior skin. All the holes are round, the boiler is sealed and locked in operation, and kept under the pressure of the furnace. Blower outlet pressure of 330 mm water column pressure of 140 mm water column.
