In order to avoid thermal expansion deformation of the brickwork, gaps for thermal expansion of the brickwork are reserved between bricks at proper positions of the brickwork.
The presence of the expansion joints affects the tightness of the furnace wall. When the boiler is at negative pressure, external cold air enters the hearth, so that the efficiency of the boiler is reduced, and the economical efficiency of the boiler is affected. When the boiler is in positive pressure, flame and smoke leak, and personnel safety and environmental sanitation are affected. In addition, the expansion joints also can influence the heat preservation performance of the boiler, and radiant heat of the hearth flame can reach the outside of the boiler through the expansion joints, so that heat loss is caused.
