Self-flowing pellet fuel environmental protection stove

Abstract

The invention discloses a self-flowing environment-friendly granular fuel furnace and belongs to clean and environment-friendly furnaces for civil use. The self-flowing environment-friendly granular fuel furnace structurally and specifically comprises a furnace body. A combustion chamber is formed in the furnace body. An economizer is arranged at a furnace mouth. A feeding port is formed in one side of the furnace body. A moving grate is arranged between the combustion chamber and an ash removal chamber. The moving grate is obliquely placed. One end of the moving grate is arranged at the intersection of the combustion chamber and the feeding port and hinged to the inner wall of the combustion chamber, and the other end of the moving grate is freely supported on the upper surface of an adjustment plate. The adjustment plate is of a cantilever structure, and the restraint end of the adjustment plate is arranged at the intersection of the combustion chamber and the ash removal chamber. According to the self-flowing environment-friendly granular fuel furnace, the thickness of a combusting fuel layer can be controlled by means of the adjustability of the inclination angle of the moving grate, and thus uniform feeding is achieved; meanwhile, through the economizer which is located at the furnace mouth and used for controlling the combustion speed, uniform and stable combustion of various kinds of granular fuel such as clean coal, small semi-coke particles and anthracite briquettes is achieved, slagging is avoided, and using is convenient and fast; and the combustion process accords with the low-nitrogen combustion principle, nitrogen oxide emission is little, and environmental friendliness and high efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of civil clean and environment-friendly stoves, in particular to an environment-friendly stove capable of automatic feeding and stable combustion. High-efficiency, environment-friendly and clean combustion of granular and granular fuels, meeting any cooking and heating requirements of users. Background technique [0002] Rural areas in northern my country are accustomed to using civilian stoves for heating and cooking during the heating period. Due to the variety of fuels available in the market, the continued use of old stoves by residents cannot meet the requirements of eco-environmental protection and will pollute the atmosphere. At this stage, under the guidance of the country's policy of building an ecological and environmental protection society, with the continuous enhancement of people's awareness of environmental protection, "promote clean fuels, replace environmentally friendly stoves, and prohibi...

AI Technical Summary

Problems solved by technology

To sum up, in view of the current market situation, combined with the combustion characteristics of several fuels, it is impossible to achieve environmentally friendly and efficient combustion at the same time with one stove, and the structural defects of the existing stoves make it have poor combustion stability, and the environmental indicators are very low. Therefore, it is urgent to design a civil cooking and heating stove that can efficiently burn clean briquettes (briquettes), anthracite lumps, and small-sized semi-coal pellet fuels.

[0004] The inventor applied for a blue charcoal pellet stove (201510822872.0) last year. This stove is suitable for burning small-sized blue charcoal materials, but the fire gathering and heating tube device in its core structure is relatively expensive, and in practical applications , Larger particles of clean coal fuel (briquette briquettes, anthracite blocks, etc.) are not convenient to feed at the rear of the heating cylinder, and there are many inconveniences in use and the defects of poor fuel versatility
