Oven kang type semi-gasified energy-saving environment-friendly furnace and manufacturing method thereof

Abstract

The invention discloses an oven kang type semi-gasified energy-saving environment-friendly furnace which comprises a burner, a gasification chamber, a charging opening, a grate, an ash collecting and ventilating chamber, a secondary air inlet channel, a panel flame surrounding cover, a circumference space, an insulating layer, a tertiary air inlet, a flame blocking ring, a direct exhaust flue, a pit inlet flue and a blower opening. The manufacturing method of the invention comprises the following steps: firstly, prefabricating various matched accessories of different sizes, and then selectingvarious proper accessories for forming a furnace core according to the height of the pin inlet flue; determining a basic line for building an oven type energy-saving environment-friendly furnace, andthen combining and fixing an oven type energy-saving environment-friendly furnace core; and finally, forming an oven by laying bricks and mud. In the invention, the biomass semi-gasified furnace technology is applied to the traditional oven kang, thereby greatly widening the application range of the biomass semi-gasified furnace; and the kang body is used as the flue of the biomass semi-gasified furnace, thereby fully utilizing the heat energy of the semi-gasified furnace. The invention can be used for standardized production, can be used for building a new oven kang and is also suitable for rebuilding the traditional oven kang.

Description

technical field [0001] The invention relates to the field of rural stove heating facilities, in particular to a stove-type semi-gasification energy-saving and environment-friendly stove. The invention also relates to a preparation method of the stove kang type semi-gasification energy-saving and environment-friendly furnace. Background technique [0002] In the vast rural areas of northern my country, due to the cold climate, traditionally use the structure of stove kang connected to make the waste heat from cooking used for heating, which not only has the effect of energy saving, but also has the effect of disease prevention, health care and recuperation for middle-aged and elderly people, women and children sleeping on kang The function of a biomass semi-gasifier combined with a traditional stove kang structure has a huge potential and a broad market. [0003] At present, there are basically two kinds of common biomass gasifiers, one is the full biomass gasifier, and the o...

Problems solved by technology

The biggest defect of the biomass full gasifier is that it produces a large amount of tar, waste water, tar vapor, dust and harmful gas emissions during use, which can easily cause gas pipelines and burners to be blocked, resulting in tar and uncontrollable part of carbon monoxide The gas will be directly discharged into the atmosphere, causing secondary pollution. In addition, the full gasifier is a separate structure for gas production and combustion, which takes up a lot of space. Therefore, it is difficult to combine the biomass full gasifier with the stove kang

Existing biomass semi-gasification furnaces are generally equipped with a combustion chamber, a gasification chamber, an air chamber and a secondary ventilation duct from top to bottom in the furnace body, or a secondary air inlet space, the gasification chamber and the air chamber Separated by the furnace bridge, its working principle is: the air chamber provides air for the gasification chamber, the biomass smolders in the gasification chamber to generate combustible gas, and the combustible gas rises to the combustion chamber and mixes with the air provided by the secondary air hole and fully Combustion solves the problem of secondary pollution. However, the existing stoves also have some defects, such as: (1) The traditional stove has a large hearth, no gas production, no secondary air distribution, direct combustion with only primary air, The efficiency of fuel is greatly wasted, black smoke is emitted from the chimney, high energy consumption, and high pollution; (2) the air sent into the existing semi-gasification furnace through the secondary ventilation pipe is cold air, and the combustion-supporting efficiency is low; (3) the air inlet channel The area is small or the ventilation is not smooth, and the combustion effect is poor; (4) Long-term use will block the secondary air distribution channel, and the wall of the gas production chamber will crack and enter the air, affecting gas production and normal combustion, etc.

So far, there is no energy-saving and environment-friendly furnace combining biomass semi-gasification furnace and stove kang
