Embodiment Construction
[0010] Embodiment of the present invention: in the design of the water wall of the circulating fluidized bed boiler, a large number of measuring points originally designed at the smooth tube screen of the furnace water wall of the circulating fluidized bed boiler are moved to the similar anti-abrasive material, so that the light The tubes are connected, so that the tube screen step protrusion at the wall passing through the furnace water wall of the circulating fluidized bed boiler is canceled, and its structure is as follows figure 2 shown.

The invention discloses an antifriction method for a circulating fluidized bed boiler furnace. The method is as follows: a wall cooled wall of a circulating fluidized bed boiler adopts a design that observation points are design to be in an antifriction material near a light tube panel instead of the light tube panel where light tube can be communicated with one another, tube panel step protrusions at positions at which a wall is penetrate are eliminated. The method is simple in design, no increase in cost, and good antifriction effect. The method can be used in boiler design and overhauling and is applicable to design of all boiler plants.
