Low-noise boiler with air preheating

Abstract

The invention discloses a low-noise boiler with air preheating. The low-noise boiler with air preheating comprises a boiler body, a combustor connected to one side of the boiler body and a chimney connected to the other side of the boiler body, wherein a mute cover is arranged outside the boiler body; an air preheating region is arranged on one side of the mute cover; a smoke exhaust hole is formed in the top part of the air preheating region; the chimney is communicated with the smoke exhaust hole and a boiler smoke outlet; an air inlet vertical to the chimney is formed in one side of the upper part of the air preheating region; a first air channel is arranged in the air preheating region; the first air channel corresponds to the position of the chimney. The low-noise boiler with air preheating is simple and beautiful in overall structure, can reduce noise of the whole boiler, improves temperature of new air and reduces energy source needed for combustion, energy consumption and combustion cost as the air preheating region is arranged at one side of the boiler body, and the new air before entering into the combustor is preheated through the air preheating region in advance, and is energy-saving and relatively environment-friendly as heat energy of waste smoke can be further recycled.

Description

technical field [0001] The invention relates to a boiler, in particular to a low-noise boiler with air preheating. Background technique [0002] At present, boilers in the market generally include a furnace body, a burner connected to the furnace body, and a chimney. Noise will be generated during the drafting process of the burner, noise will be generated during the combustion process of the burner, and noise will also be generated during the smoke exhaust process of the chimney, so it needs to be improved. The boiler structure is used to reduce or eliminate noise, and in general, the fresh air drawn by the burner is generally normal temperature air. Compared with the air with a higher temperature, more energy is consumed during the combustion process, so energy consumption is increased and combustion is improved. cost. Contents of the invention [0003] In order to solve the defects and deficiencies of the above-mentioned prior art, the present invention provides a simp...
