Building construction method for expansion device of household garbage incineration boiler

Abstract

The invention discloses a building construction method for an expansion device of a household garbage incineration boiler. The building construction method comprises the following steps of construction preparation and inspection, welding of furnace wall metal pieces, construction of pouring materials on the inner side of the upper portion of the expansion device, construction of pouring materials on the lower portion of the expansion device, laying of Z-shaped expansion joint aluminum silicate fiber cotton, installation of phi 120 aluminum silicate fiber ropes and construction of pouring materials on the outer side of the upper portion of the expansion device. When the construction method is used for building the expansion device of the household garbage incineration boiler, the problems of deformation and damage of the expansion device of the household garbage incineration boiler and a building layer in the area range of the expansion device can be effectively solved; the phenomena of throttling, blocking, coke hanging and the like caused by burning loss, damage, cracking and falling of the building layer are effectively avoided; normal and stable operation of a unit is guaranteed; the overhaul and maintenance period is shortened; the combustion efficiency of the boiler is stabilized; environmental pollution is reduced; the technology is advanced; and practicability is high.

Description

Technical field: [0001] The invention relates to a masonry construction method for an expansion device, in particular to a construction method for a domestic waste incineration boiler expansion device. Background technique: [0002] For the masonry construction of the expansion device of the domestic waste incineration boiler, the expansion joints are generally left straight and filled with aluminum silicate fiber cotton. The boiler is in a long-term continuous operation state, and the high-temperature flowing flue gas will wash away the aluminum silicate fiber cotton in the expansion joint for a long time, and the phenomenon of "hollowing out" will occur, which will damage the expansion device and the upper and lower masonry materials of the expansion device, causing coking The phenomenon is serious, resulting in frequent overhaul and maintenance cycles of incinerators, resulting in waste of resources and reduced benefits. Invention content: [0003] The technical proble...
