Energy-saving, environment-friendly, easy-dusting, air-heated civil boiler

Abstract

The invention discloses a multifunctional civil boiler, which comprises a furnace, a flue and an air supply device, wherein the inner walls of the flue are encircled into a lower flue cavity body, a middle flue cavity body and an upper flue cavity body all of which are folded back and communicated with each other from beginning to end; a smoke passing component is arranged in the middle flue cavity body; the left side and the right side of the smoke passing component are connected with the middle flue cavity body; and the smoke passing component is internally provided with a plurality of smoke passing tubes which are parallel to the ground and spaced from each other at slight intervals. The heat efficiency of the air-heated boiler of the invention reaches above 85%; by employing the pioneering smoke passing component, the boiler has a multi-tube anti-smoking type structure; the planar absorption and the multi-tube absorption are realized; the utilization mode of the previous coal burning orientation is completely changed; in the aspect of clearing up soot, the majority of manufacturers take down the chimney in the process of clearing up the soot in the furnace in order to clear updusts; however, by using the product of the invention, the chimney does not need to be taken down when the dusts are cleared; the smoke and dusts can be cleaned up easily for 2 minutes; the product is shortcut and convenient; the cleaned soot can be secondarily burnt; and the effect of sufficiently utilizing fire coal is achieved.

Description

technical field [0001] The invention belongs to the field of boilers, and in particular relates to a multifunctional civil boiler which integrates energy saving, environmental protection and easy ash removal, and uses air as a heating medium. Background technique [0002] The heating methods of residential buildings in winter can be centralized heating, central air conditioning (including electric heating) and water heating (earth heating) due to different families and environments. The cost of electric air conditioning and central heating is very high. Therefore, water heating has always been the first choice for ordinary residents. The water heater generally used at present is to directly heat the air by the heat transfer of the furnace body or take water as the heating medium to heat the room through the radiator (radiator). Water is used as the solvent, because the specific heat capacity of water is relatively large, and the maximum temperature of water is only 100°C, s...

AI Technical Summary

Problems solved by technology

Water is used as the solvent, because the specific heat capacity of water is relatively large, and the maximum temperature of water is only 100°C, so the indoor temperature rises very slowly during heating, and the heat exchange rate is not high. In addition, a plumbing boiler adopts a direct-drawing exhaust Smoke, most of the heat generated by coal combustion in the furnace is directly discharged from the chimney, which makes the amount of coal used is large; and the indoor hot and cold air flows slowly, the temperature difference is large, the indoor heating pollution is serious, the thermal efficiency is not high, and there are often dangers such as explosions. In addition, most heating furnaces use drinking water as the heating medium, which wastes water resources; the service life of water heating furnaces is also relatively low, and one needs to be replaced after 2-3 years; High precision requirements for strands, large amount of materials, labor-intensive and material-intensive

More importantly, using coal as fuel will produce a lot of soot in the flue, which is not easy to remove

Chinese patent CN2360742Y discloses a furnace using air as the heating medium. However, the flue adopts an ordinary air duct design, and the heat loss of coal combustion is astonishing. It is not easy to remove soot, and the above-mentioned main technical problems are not solved.
