Gas heating furnace capable of achieving utilization of waste heat

Abstract

The invention discloses a gas heating furnace capable of achieving utilization of waste heat, and belongs to the field of heating equipment. According to the key points of the technical scheme, the gas heating furnace comprises a furnace body, a table top and a fire pan, wherein the table top is fixedly connected to the top of the furnace body; the fire pan is embedded in the center of the table top, and a baffle with through holes in the surface is placed on the top of the fire pan; a combustion device is arranged in the fire pan; an inner furnace is fixedly installed in the furnace body, and a preheating pipe is wound on the surface of the inner furnace; one end of the preheating pipe communicates with the fire pan, used for providing gas for the combustion device, and connected with external gas supply equipment; a recombustion device is arranged in the inner furnace; and an air extractor is arranged at a gap between the furnace body and the inner furnace, and used for extracting smoke generated in the fire pan into the recombustion device. The gas heating furnace has the effects that gas combustion is more sufficient, accumulation of poisonous gas is reduced, and therefore potential safety hazards are reduced.

Description

technical field [0001] The invention relates to the field of heating equipment, more specifically it relates to a gas heating stove with available waste heat. Background technique [0002] In the northeast or northwest of our country, in winter, the temperature is mostly below 0 degrees, and there are even extremely cold weather such as minus 20 degrees to minus 30 degrees, including other extremely cold regions around the world. In winter, people need heating when they are indoors. For cities, heating systems can be used for central heating. The stove provides heat. [0003] At present, during the use of heating stoves that use gas as energy, there are often situations of insufficient combustion, especially for extremely cold regions, most of the heating environments are closed indoors, and most of the gas used by people is gas, which does not burn well. It is easy to produce harmful substances such as carbon monoxide when it is full, and it is easy to cause indoor carbon...
