Example Embodiment
[0013] Such as figure 1 As shown, this is achieved in the present invention. The flat steel 2 is evenly provided with small holes 7 and the flat steel 2 and the water-cooled tube 3 are alternately welded together to form a "membrane water-cooled wall". The membrane water-cooled wall and the holding furnace wall 5 are separated by an appropriate distance to form an annular cavity 4. The air pipeline 6 is installed on the heat preservation furnace 5 and communicates with the cavity 4.
[0014] The specific working process of the present invention is: air continuously enters through the air pipe 6 and fills the cavity 4, the flat steel 2 with small holes 7 and the water cooling pipe 3 are welded to form a film water wall, and the air in the cavity 4 penetrates Passing through the small holes 7, an air film 1 is formed on the surface of the membrane water wall to prevent the pulverized coal air flow 8 from directly washing the water wall, thereby preventing coking and high temperatur...
