Abstract

The utility model provides an environment-friendly and energy-saving stove, which consists of a stove body, a stove chamber in it, a stove head on it, a stove bottom with a stove bar and a stove door under it, and a stove set between the stove body and the stove bottom. The water tank outside the stove is characterized in that there is a secondary air duct whose lower part communicates with the stove door and whose upper part communicates with the stove head between the stove chamber and the stove body. The traditional direct combustion method is changed to the secondary combustion method, which not only makes the thermal efficiency reach 60-70%, the flame temperature reaches 900-1000 degrees, but also saves fuel by 50-60%. At the same time, it is smoke-free, dust-free and clean. , In addition, the utility model also has the characteristics of simple structure, light weight, easy handling, fast ignition, adjustable firepower, high temperature, and energy saving.

Description

Environmental protection and energy saving stove

technical field

The utility model relates to a household stove, in particular to an environment-friendly and energy-saving stove using biomass fuel.

Background technique

At present, most of the stoves used in vast rural areas are coal-fired or wood-fired stoves. On the one hand, it will consume a large amount of coal and forest resources, destroy vegetation, cause serious soil erosion, and thus affect the living environment that our people rely on for survival. On the other hand, a large amount of crop biomass such as orange stalks, wheat stalks, rice husks and other combustible substances have not been effectively utilized. Therefore, it is necessary to develop a high-efficiency, safe and energy-saving stove that can make full use of combustible biomass and save wood resources.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies of the prior art and provide an environment-friendly and energy-saving stove with high thermal efficiency and good gasification effect.

The utility model is realized through the following technical solutions: it consists of a stove body, a stove chamber inside it, a stove head on it, a stove bottom with a stove bar and a stove door under it, and a stove chamber arranged between the stove body and the stove bottom. The external water tank is composed of a secondary air duct whose lower part communicates with the cooker door and whose upper part communicates with the cooker head between the cooker chamber and the cooker body.

The lower part of the secondary air duct communicates with the stove door through the grate gap, and the upper part communicates with the stove head through the through hole on the wall of the stove, so that the combustion-supporting air is introduced from the bottom of the stove, and then sent into the stove head through the secondary air duct to support combustion again. , increase firepower, reduce fuel volume.

The water tank is provided with a steam pipe, and the other end of the steam pipe communicates with the hole on the wall of the stove, so as to provide combustion-supporting hydrogen and oxygen gas into the stove, so as to gasify the combustion materials, thereby improving the thermal efficiency.

Compared with the prior art, the utility model has the following advantages and effects: due to the above scheme, the traditional direct combustion method is changed to a secondary combustion method, not only the thermal efficiency reaches 60-70%, the flame temperature reaches 900-1000 degrees, and It can save fuel by 50-60%. At the same time, it is smoke-free, dust-free, clean and hygienic. In addition, the utility model also has the characteristics of simple structure, light weight, easy handling, fast ignition, strong firepower, high temperature, controllability, energy saving, etc. , is an environmentally friendly and energy-saving biomass fuel stove suitable for use in vast rural areas.

Detailed ways

Fig. 1 is the structural representation of the utility model.

Below in conjunction with accompanying drawing, the utility model is further described.

In the figure, 1 is the stove head, 2 is the stove body, and 3 is the stove chamber. The upper wall is provided with a plurality of secondary air inlets 31, the lower wall is provided with at least two steam inlets 32, and the bottom is provided with a grate 33. , 4 is an annular water tank, located on the periphery of the stove between the stove body and the bottom of the stove, the water tank is provided with a water inlet 41, a water outlet 42 and a steam pipe 43, and the other end of the steam pipe communicates with the steam inlet 32 on the wall of the stove , when the water in the water tank is heated up, the steam generated enters the stove through the steam pipe 43 and the steam inlet 32 to support combustion. The air intake can control the firepower, which has changed the problem that similar products cannot adjust the firepower, making it more convenient and practical. It communicates with the damper 51, and the upper end communicates with the stove through the secondary air inlet 31 on the wall of the stove, so as to provide the stove with combustion-supporting gas for secondary combustion. The amount of the combustion-supporting gas is adjusted by the damper 51 to increase the firepower. The smoke exhaust port on the top is connected to the chimney to remove the smoke generated during ignition.
