Embodiment Construction

[0008] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0009] As shown in the figure, a casting furnace arch of an industrial boiler includes a front arch 1 and a rear arch 2. The furnace arch is a cast-type structure. The height of the outlet of the front arch 1 is higher than the height of the front port of the rear arch 2, and the front arch 1 is a hyperbolic paraboloid. , The rear arch 2 is flat, inclined, and reverse-inclined from the back to the front. There is an expansion joint 3 on the furnace arch, and the arch bar 4 is separated from the arch foot 5.

[0010] In the accompanying drawings: 1 is the front arch; 2 is the rear arch; 3 is the expansion joint; 4 is the arch bar; 5 is the arch foot.

Abstract

The invention discloses a pouring furnace arch for an industrial boiler. The pouring furnace arch comprises a front arch and a rear arch, wherein the furnace arch has a pouring structure; height of an outlet of the front arch is higher than that of a front port of the rear arch; the front arch has a hyperbolic paraboloid; the rear arch has a flat shape, an oblique shaped and inverted oblique shape from front to rear in turn; a dilatation joint is formed on the furnace arch; and an arch strip is separated from an arch pin. The pouring furnace arch for an industrial boiler provided by the invention has the advantages of low thermal stress, high radiation, high thermal efficiency, long service life, low cost and the like; meanwhile, waste fire-resistant materials can be recycled, and the pouring furnace arch has excellent social, economic and environmental benefits, convenience in construction and reconstruction and wide popularization and application prospects.

Description

technical field [0001] The invention relates to the field of boilers, in particular to an industrial boiler casting furnace arch. Background technique [0002] Traditional industrial boiler arches are made of refractory bricks, with irregular shapes, many joints, large internal stress, poor radiation heat accumulation effect on coal combustion, short service life, and refractory materials are difficult to reuse, causing environmental pollution. Pollution, high cost. Contents of the invention [0003] In order to overcome the defects of the above-mentioned prior art, the object of the present invention is to provide a casting furnace arch of an industrial boiler, which has low thermal stress and strong radiation, and has the advantages of long life, low cost and good environmental benefits. [0004] For achieving above-mentioned purpose, technical scheme of the present invention is as follows: [0005] A casting furnace arch for an industrial boiler, including a front arc...
