烟囱的内衬,高度7.5米至9.5米、30米至110米为红机砖,用~#50混合砂浆砌筑。高度9.5米至30米、110米至120米为耐火砖,用耐火泥砌筑。内衬厚度,17.5米以下为一砖,17.5米以上为半砖。(一)砌砖施工平台砌砖施工平台由内钢圈、底座钢梁、弧形钢木脚手板等组成,如图18。平台最大外径φ7.2米.自重2.92吨。为适应烟囱内径逐渐缩小的特点,平台的外径可以分别缩小为φ6.7、
Chimney lining, height 7.5 meters to 9.5 meters, 30 meters to 110 meters for the red brick machine, with ~ # 50 mixed mortar masonry. Height 9.5 meters to 30 meters, 110 meters to 120 meters for refractory brick, with refractory mud masonry. Lining thickness, 17.5 meters below a brick, 17.5 meters above half-brick. (A) Brick Construction Platform Brick construction platform from the inner ring, the base steel beam, curved steel wood scaffolding and other components, as shown in Figure 18. The largest diameter of the platform φ7.2 meters. Weight 2.92 tons. In order to adapt to the chimney diameter is gradually reduced, the outer diameter of the platform can be reduced to φ6.7,
