Embodiment Construction
[0041] Such as figure 1 As shown, a kind of circulating fluidized bed boiler return feeder local insulation layer lining repair method of the present invention comprises the following steps:
[0042] Step 1, determine the cavity 11 of the heat insulation layer: firstly determine the damage of the heat insulation layer according to the overtemperature of the wall 1 of the returner cylinder during daily operation, tap the surrounding area of the overtemperature part with a hammer, and determine the insulation by listening to the sound. Thermosphere cavity 11 scope;
[0043] Step 2, opening repair holes 12: opening several repair holes 12 at the corners around the cavity 11 of the heat insulation layer;
[0044] When the repair hole 12 is opened, the metal anchor 10 needs to be avoided, and it is opened on the wall 1 of the returner cylinder at the cavity 11 of the heat insulation layer at intervals of 500mm in the circumferential direction and the axial direction respectively...
