Energy-collecting heat exchange environment-friendly boiler

Abstract

The invention relates to an energy-collecting heat exchange environment-friendly boiler. The boiler comprises a boiler body, wherein the boiler body comprises a hearth and a secondary combustion chamber which is arranged above the hearth and is communicated with the upper side of the hearth; a heat exchanger is arranged above the boiler body; a back wall of the secondary combustion chamber is a windward wall; a flame path is formed between the back wall of the secondary combustion chamber and a back wall of the hearth; a flue is formed between a back wall of the boiler body and the windward wall; on the lower part of the windward wall, a space formed by the back wall of the hearth, left and right walls of the boiler body and the back wall of the boiler body is taken as a dust settling chamber; the flame path is communicated with the flue through the dust settling chamber, thereby forming a U-shaped channel. By adopting the energy-collecting heat exchange environment-friendly boiler, in order to solve the problem concerned with dust reduction, the windward wall is arranged in front of the flue, the upper part of the windward wall is connected with the top of the secondary combustion chamber, and the lower part of the windward wall is suspended into the settling chamber; the flame path, the settling chamber and the flame path construct the U-shaped channel; under the action of wind power and gravity, ash included in smoke gas can be settled in the settling chamber, so that the emission of ash into the atmospheric air is reduced.

Description

technical field [0001] The invention relates to a boiler, in particular to an energy-collecting and heat-exchanging environment-friendly boiler. Background technique [0002] Boiler is a kind of energy conversion equipment, which mainly outputs steam, high-temperature water or organic heat carrier with certain heat energy, and is widely used in domestic and industrial production. There are many kinds of boilers on the market now, and they are introduced from the old to the new, with different forms and structures. [0003] Designing boilers from the perspective of energy conservation and environmental protection is a common idea for boiler workers. How to release all the energy value of fuel through combustion, how to maximize the conversion of heat energy obtained, and how to reduce slag and smoke are all important aspects of every boiler design. goal of the people. Although there are many researches and improvements on the market at present, such as secondary combustion...
