And the cooling water bag (12) can take away a large amount of heat in the kiln, thereby causing high energy consumption of the kiln.

2) In order to ensure the steel structure strength of the L-shaped hanging wall (11) and achieve the purpose of supporting the weight of the whole L-shaped hanging wall, the steel structure of the L-shaped hanging wall (11) needs to be blown and cooled, and a large amount of heat in the kiln can be taken away by cooling air, so that the energy consumption of the kiln is high.

3) The refractory material selected by the lower structure of the L hanging wall (11) is a small refractory material, so that more brick joints are caused, the refractory material is easy to corrode, and the service life of the kiln is shortened.

4) The L-shaped hanging wall (11) is complex in structure, high in installation difficulty and difficult to maintain in a production state.
