Refractory bricks for boiler masonry

Abstract

The invention belongs to the technical field of refractory materials, and particularly discloses refractory bricks for boiler masonry. The refractory bricks comprise refractory brick bodies; first channels and through second channels are uniformly formed in the refractory brick bodies; the first channels are correspondingly perpendicular to the second channels and communicate with the second channels; and one ends of the first channels communicate with the inner part of a boiler; a group of first holes are uniformly formed in the bottoms of the refractory brick bodies, and a group of clampingcolumns are uniformly arranged at the tops of the refractory brick bodies; and the lamping columns are composed of first columns and elastic second columns. According to the refractory bricks, throughthe mutual matching between the first columns, the second columns and the first holes, the adjacent refractory brick bodies are clamped together, and gaps between the adjacent refractory brick bodiesare reduced; and meanwhile, after the boiler masonry is completed, the second channels on the adjacent refractory brick bodies communicate with each other to form an annular channel, the hot gas in the boiler enters from the first channels and enters into the second channels sequentially, and the heat preservation of the boiler is achieved.

Description

technical field [0001] The invention belongs to the technical field of refractory materials, in particular to a refractory brick for boiler masonry. Background technique [0002] Refractory materials are generally divided into two types, namely unshaped refractory materials and shaped refractory materials. Unshaped refractories are also called castables, which are mixed powdery particles composed of various aggregates or aggregates and one or more binders. When used, they must be mixed with one or more liquids and stirred evenly. Strong mobility. Shaped refractory materials generally refer to refractory bricks, whose shape has standard rules, and can also be temporarily processed when building and cutting according to needs. [0003] Refractory bricks are referred to as firebricks. Refractory materials made of refractory clay or other refractory raw materials. Pale yellow or brownish. It is mainly used to build smelting furnaces, which can withstand high temperatures of...

AI Technical Summary

Problems solved by technology

[0006] In order to make up for the deficiencies of the existing technology and solve the existing problem of building refractory bricks in the boiler, there is a gap between two adjacent refractory brick bodies, which causes the hot gas in the boiler to easily spray out to the outside of the boiler, and the heat in the boiler Insufficient problem, a kind of boiler masonry that the present invention proposes uses refractory brick
