Problems solved by technology
However, due to the short residence time of the flame in the kiln, this kind of kiln cannot conduct sufficient heat exchange with the workpiece. Most of the heat is directly discharged into the atmosphere through the flue, which is wasted in vain. In addition to the heat dissipation of the kiln body, the thermal efficiency is only 3% to 5%, energy consumption accounts for about 40% of the production cost of ceramics, so saving energy is the key issue in reducing production costs in ceramic production
Although some kilns have taken many measures for energy saving, the energy saving effect is still not ideal due to the structure and heating method of the kiln.

Embodiment Construction
[0014] Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0015] Such as figure 1 .combine figure 2 , image 3 As shown, the gas-fired kiln provided with the radiant pipeline device according to the present invention,
[0016] It includes kiln body 1, furnace door 2, gas burner 3, radiant pipe 4, fire suction hole 5 and flue 6. Furnace door 2 is located at one end of kiln body 1. After the furnace door 2 is closed, it forms an airtight chamber in the kiln body 1. heating chamber. A gas burner 3 is arranged on the side wall of the heating chamber. Multiple groups of radiation pipes 4 are arranged on the side wall of the heating chamber. In order to increase the heat conduction area of the radiation pipes and increase the thermal conductivity, the radiation pipes can be made of thin-walled silicon nitride with good thermal conductivity combined with silicon carbide. Recrystallized silicon ...

The invention discloses a gas kiln provided with a radiation pipeline device, which comprises a kiln body (1), a kiln door (2), gas nozzles (3) and a flue (6), wherein the kiln door is located at one end of the kiln body; the gas nozzles are arranged on a side wall of the kiln body; fire sucking holes (5) are formed at the kiln bottom of a heating chamber in the kiln body (1); a plurality of radiation pipelines (4) are arranged on an inner wall of the heating chamber in the kiln body (1); one end of each radiation pipeline is connected with the fire sucking holes at the kiln bottom; and the other end of each radiation pipeline is communicated with the flue (6). According to the gas kiln, the residence time of flames can be prolonged in the kiln by a system during a working period of the kiln, and sufficient heat exchange is conducted on a workpiece, so that the heat efficiency is improved, and purposes of high efficiency and energy conservation are achieved.
Description
technical field [0001] The invention belongs to the technical field of intermittent gas furnaces, and in particular relates to a gas furnace provided with a radiation pipeline device. Background technique [0002] Batch kiln is a commonly used firing equipment in ceramics and other industries. At present, the gas-fired drawer-type and shuttle-type kilns used are all batch-type kilns. Due to the characteristics of simple structure, low construction cost, small temperature difference in the kiln, and flexible and convenient production adjustment, the batch-type kiln is widely used in Daily use, crafts, sanitary ceramics and other industries. This kind of kiln is flexible and convenient for the firing of small batches and many varieties of products, and is an indispensable heating and firing equipment for these industries. However, due to the short residence time of the flame in the kiln, this kind of kiln cannot conduct sufficient heat exchange with the workpiece. Most of th...
