Due to the lack of new and efficient combustion devices that are compatible with biomass fuels, it is impossible to make biomass fuels play a role in the vast rural areas. greater effect. Some even can only burn a large amount of biomass materials in the open air, which not only wastes a lot of precious resources, but also pollutes the environment. For the biomass burning furnace, there are many types at present, but because this type of burning furnace still adopts the traditional furnace body structure and the traditional manual feeding and burning method, it is very inconvenient to use, not only difficult to feed, heavy odor, pollution environment, and the thermal efficiency utilization rate is very low, it can only be used for general heating and cooking, and it is difficult to play a greater role in other heating, drying, and hot water engineering fields.

The technical scheme adopted by the utility model to solve the technical problems is: this multifunctional compound biomass combustion furnace is provided with a base, a furnace body, a furnace, a soot cleaning port and a chimney, mainly because the furnace body is connected with a feed port and the combustion chamber of the feed chamber. The combustion chamber is connected to the furnace through a high-temperature fire channel. A grate is arranged at the lower part of the combustion chamber, and an ignition port and an air regulating hole are arranged on the outside of it. Oxygen-increasing pipe and fire guide leading to the furnace; the upper part of the furnace is provided with a furnace cover with a furnace cover, and the bottom of the furnace is connected to the smoke collection chamber and the flue through a number of 1 to 10 fire pipes, and the flue and the chimney There are water jackets around the combustion chamber, furnace, fire pipe and chimney, water outlets and water inlets are provided on the water jackets, an insulation layer is provided on the outer surface of the water jackets, and water jackets, furnaces, fire pipes 1. The inner wall of the combustion chamber is provided with a high-temperature refractory material layer; a connecting pipe is provided between the combustion chamber and the chimney.

The main advantages of the utility model compared with the prior art:

First, it is practical and easy to promote and use. Since it can be used in conjunction with the biomass fuel automatic adding device, the combustion chamber and the furnace are arranged side by side in structure to meet the needs of various biomass fuel combustion, and all biomass fuel does not need any crushing or briquetting , carbonization and other processing, it can be directly burned and used. Therefore, local raw materials can be obtained and various raw biomass can be used as fuel, which greatly improves the practicability of the combustion furnace and the value of popularization and use in rural areas.

Second, the design is reasonable, the structure is novel, and the thermal efficiency utilization rate of combustion is high. Mainly according to the characteristics of biomass combustion, an oxygen-increasing tube is set between the combustion chamber and the furnace to make the combustion more complete. At the same time, a water jacket is provided around the combustion chamber, furnace and chimney, so that the waste heat of combustion can be fully utilized. These new designs are conducive to the full combustion of biomass fuels and also improve the utilization efficiency of heat energy.

Third, the utility model not only changes the problem that the traditional biomass fuel can only be used for cooking and boiling water, but also solves the heating problem of using biomass fuel for heating and drying. The utilization value of material energy, and as long as the majority of farmers and herdsmen families have such a stove, they can live very conveniently.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described in detail:

As shown in Figures 1 and 2, this multifunctional composite biomass combustion furnace is provided with a base 11, a furnace body 7 integrated with the base 11, a furnace 6, and a soot cleaning port 22 and a chimney 2 arranged in the base 11, mainly The furnace body 7 is connected to the combustion chamber 16 with the feed port 12 and the feed chamber 14, a row of fire grates 20 are arranged obliquely at the lower part of the combustion chamber 16, and an ignition port 17 and an air regulating hole are arranged on the outside of the combustion chamber 16. 19. The combustion chamber 16 is connected to the furnace 6 through a high-temperature flue 15. Between the combustion chamber 16 and the furnace 6, an oxygen-increasing pipe 18 with air holes and a fire guide plate 4 leading to the furnace 6 are arranged horizontally between the combustion chamber 16 and the furnace 6. The oxygen-increasing pipe 18 The two ends of the furnace pass through the furnace body 7 to communicate with the atmosphere; the upper part of the furnace 6 is provided with a furnace platform 5 with a furnace cover, and the bottom of the furnace 6 is connected to the smoke collection chamber 10 and the flue 8 through two fire pipes 9, and the flue 8 is connected to the chimney. 2 are connected; the periphery of the combustion chamber 16, the furnace 6 and the chimney 2 are provided with interconnected water jackets 3, and the water jacket 3 arranged around the chimney 2 is provided with a water outlet 1, and the water jacket 3 at the bottom of the combustion chamber There is a water inlet 21 on it.
