Description

Technical Field

[0001] The utility model relates to the technical field of coal stoves, in particular to a three-pipe iron cast coal stove. Background Art

[0002] The working principle of a coal stove is mainly to generate heat by burning fuel such as coal. During the combustion process, the carbon element in the fuel reacts chemically with the oxygen in the air to generate heat energy. This heat energy is transferred to the surrounding space or used for cooking through the stove body and the fire grid, and the smoke generated is discharged through the flue.

[0003] In addition, coal stoves are widely used in many fields. In addition to family life, coal stoves are also widely used in machinery, metallurgy, chemical industry, light industry, building materials, glass and other industries as secondary energy equipment for various heating furnaces and industrial kilns. In these industries, coal stoves play an important role in providing a stable heat source and promoting the process.

[0007] Furthermore, an ash port assembly and a coal feeding port assembly are arranged on the front plate assembly.

[0008] Furthermore, the coal feeding port assembly is arranged directly above the ash port assembly.

[0009] Furthermore, the heat exchange pipe openings are three pipe openings arranged in a line from front to back, and the outer side of the heat exchange pipe openings is also covered with a fixed groove outer ring.

[0010] Furthermore, the top plate is provided with corners at four sides.

[0011] Furthermore, a refractory cement lining is built inside the furnace body, and furnace bars are arranged outside the furnace body.

[0012] Furthermore, a nameplate is provided on the cover plate of the ash port assembly, and the nameplate is fixed by using fixing rivets.

[0013] Furthermore, the top of the chimney cap is a cover plate, which is an inverted V-shaped folding flat plate. The cover plate is fixed under a support rod, and a connecting rod is arranged at the lower end of the support rod.

[0014] Furthermore, it also includes a spoiler string with a number of spoiler plates evenly fixed on the spoiler rod, a handle is provided at the bottom of the spoiler string, a hook is provided at the top, and an anti-hooking card is provided on the inner side of the hook.

[0015] Beneficial effects of the utility model: the utility model improves the heat exchange efficiency of the coal furnace and increases the exhaust gas emission by setting a plurality of heat exchange pipe openings. BRIEF DESCRIPTION OF THE DRAWINGS
