A method of attaching a boiler tube protectors having a cylindrical or semi-cylindrical shape around an outer peripheral face of a boiler tube with mortar, which boiler tube protectors, are a plurality of ceramic bodies closely arranged along their parting planes, wherein the parting planes includes means for restraining slippage of each of the ceramic bodies along the parting planes.

Water pipe protecting refractory structure

The present invention aims for the object thereof at preventing unburnt gas and noxious gas components from being generated in a refuse incinerator, and provides a combustion control method by which it is arranged so that a feeder (2) and a stoker (3) are not only controlled so as to keep evaporation (S1) of the boiler at a target value thereby to achieve stabilized combustion extending over a long period of time, but also feed water quantity (S2) and the like from a boiler water pipe section (2) forming a combustion chamber (6) are detected, and the rate of overfire air quantity to main combustion air quantity to a lower part of the stoker is controlled at a constant total gas capacity so that the fluctuation width of the feed water quantity (S2) falls within a set range.
