(1) The heat insulation board should be built close to the furnace shell. The internal and external joints of the two layers of heat insulation boards are wrong. If the joint width is greater than the local gap between the heat insulation board and the furnace shell and is greater than 3mm, refractory fiber should be filled.
(2) The masonry expansion joints must be retained according to the designed size, no negative error shall occur, and the joints must be filled with refractory fiber.
(3) The refractory bricks around the thermometer sleeve, soot blower and steam pipe hole should be processed into a trumpet shape according to the design size. The gap between the refractory bricks and the pipe should be filled with refractory fiber.
(4) Before laying the side wall burner bricks, the bottom brick layer should be leveled by pulling wires, and the deviation of the burner brick fixing frame should be checked to make it meet the design requirements.
(5) The burner bricks should be pre-numbered. When the center line of the burner brick assembly overlaps with the center line of the metal burner, mud masonry can be used, otherwise it will cause deviation of the combustion air flow and affect the stability of combustion. The gap between the burner brick and the metal burner should be consistent and filled with refractory fiber.
(6) The peep hole bricks should be pre-assembled, the brick supports and hangers should be installed correctly, and the allowable error of the center line of the peep hole bricks is ±5mm.
