Composite burner brick for heating furnace kiln

Abstract

The invention relates to a composite burner tile for a heating furnace. The composite burner tile is characterized in that the shape of a composite insulating assembly is a quadrangular prism which sequentially consists of a glass state insulating fiber (5), a crystalline state insulating fiber (6), a square-hole insulating assembly (7) and a casting material prefabricated assembly (4). A through hole with a changeable diameter is formed in the center of the quadrangular prism, and a casing pipe (3) with a changeable diameter is inlaid in the through hole with the changeable diameter. Four bolt holes are symmetrically formed in the glass state insulating fiber (5) and the crystalline state insulating fiber (6) along the diagonal lines, and Y-shaped anchoring nails (8) of anchoring devices (2) are symmetrically arranged at four corners of a small square boss of the casting material prefabricated assembly (4); one ends of loop bars (9) of the anchoring devices (2) are connected with the Y-shaped anchoring nails (8), and the other ends of the loop bars (9) of the four anchoring devices (2) penetrate through the corresponding bolt holes and are connected with a stainless steel plate (1). The composite burner tile disclosed by the invention has the characteristics of being light in weight, good in insulating property, high in intensity, high in erosion resistance, easy in repair and maintenance, good in using effect and long in service life, and is suitable for various heating furnaces in petrifaction trades.

Description

technical field [0001] The invention belongs to the technical field of composite burner bricks. In particular, it relates to a composite burner brick for a heating furnace kiln. Background technique [0002] Burner brick is one of the important parts of various heating furnaces. Traditional burner bricks mostly use heavy refractory materials, and light insulation materials are rarely used. With the increasing scarcity of energy, improving the heat insulation effect of burners and reducing heat loss has become one of the important issues that the industry needs to solve urgently. Among them, one of the effective ways is to use lightweight heat insulation materials to improve the heat insulation effect of burner bricks, but all light heat insulation materials have disadvantages such as low high temperature strength, corrosion resistance and easy peeling. For example, the patented technology of "a rapid cooling and rapid heating burner brick and its preparation method" (CN 1...

AI Technical Summary

Problems solved by technology

Among them, one of the effective ways is to use light heat insulation materials to improve the thermal insulation effect of burner bricks, but all light heat insulation materials have disadvantages such as low high temperature strength, corrosion resistance and easy peeling.

For example, the patented technology of "a rapid cooling and rapid heating burner brick and its preparation method" (CN 101182222A), the technology uses aluminum powder, high alumina bauxite aggregate, bauxite fine powder and chromium oxide fine powder as main raw materials , press molding under 60~100MPa pressure to produce a rapid cooling and rapid heating burner brick. Although the burner brick has excellent thermal shock resistance, it has the disadvantages of heavy weight, difficult installation, poor heat insulation performance and easy peeling.

Another example is the patented technology of "ceramic fiber burner brick" (CN 200946985Y). The burner brick in this technology is composed of ceramic fiber block structure densely interwoven in warp and weft directions. Although the prepared burner brick has quality Lightweight, easy to install and good heat insulation effect, but there are disadvantages such as low strength, poor corrosion resistance and short service life
