Air-cooled combustion chamber and combustor using same

Abstract

The invention discloses an air-cooled combustion chamber and a combustor using same. The air-cooled combustion chamber involves a combustion chamber body and the combustor, wherein the combustor is arranged inside the combustion chamber body, an air-cooling channel is arranged on the periphery of the combustion chamber body, the combustion chamber body is surrounded by the air-cooling channel, and the air-cooling channel rapidly cools the combustion chamber body in a positive pressure or negative pressure mode. According to the air-cooled combustion chamber, the independent air-cooling channel is additionally arranged, and the temperature of the combustion chamber is reduced and controlled in an air cooling mode so as to achieve the purposes of environmental protection, no pollution, good heat insulation, high efficiency, good sound insulation effect, etc., so that the heat exchange efficiency and the energy efficiency ratio are improved.

Description

technical field [0001] The invention relates to the field of burners, in particular to an air-cooled combustion chamber and a burner using the same. Background technique [0002] In the current existing technology, both gas-fired heating water heaters and gas-fired water heaters need to use burners, and as the country strengthens environmental protection, the combustion emission indicators for gas appliances are becoming more and more stringent. [0003] Existing wall-hung boilers generally use heat insulation board materials to reduce heat loss in the combustion chamber. The heat insulation board is made of various fibers bonded and pressed by glue, which has the following disadvantages: [0004] (1) It is not environmentally friendly, and it will produce an unpleasant temperature when it is used for the first time; [0005] (2) The heat insulation effect is not good, the temperature of the sheet metal around the combustion chamber is generally around 180°C, and the heat l...
