The invention discloses an arrangement structure of an incinerator brickwork suitable for a household refuse incineration power plant. The incinerator brickwork adopts a three-section type mechanical reciprocating grate to burn household refuse; the body of the incinerator brickwork is divided into different areas according to the incinerator brickwork functions, fire-resistant and thermal insulating material adaptive to the area characteristic is selected for the same area to carry out combined arrangement so as to maintain the normal operation of the entire refuse incinerator; in addition, on the premise of ensuring that combustible basis in the incinerator refuse fully burns, the local high-temperature area in the incinerator is reduced, and the ash content in fuel is prevented from constant softening development from the liquid state, so that the phenomenon that the brickwork seriously cokes in the high temperature area of the fire grate of the combustion section is effectively reduced or prevented, and furnace shut down caused by coking of the incinerator is reduced. Compared with the incinerator adopting the thermal insulating brickwork structure, an air cooling wall is added to prolong the decoking period from 4 months to 6 months or longer of the interior of the incinerator, and the service life of the incinerator can be prolonged by 10% or above.
