Description

Biomass high-efficiency energy-saving and environmental protection furnace

technical field

The utility model relates to a stove, in particular to a high-efficiency, energy-saving and environment-friendly biomass stove for burning biomass (referring to dry plant stems such as straw, fruit tree branches, etc.).

Background technique

In the prior art, in order to improve the thermal efficiency of the combustion furnace using biomass as fuel, a cone-shaped burner connecting the furnace and the stove is installed between the hearth and the stove, and there are holes on the side wall of the burner. Single row of combustion-supporting holes, through the secondary air distribution through the combustion-supporting holes, the biomass in the furnace can be fully burned, thereby improving the thermal efficiency during use, but because the combustion-supporting holes are directly connected to the air chamber through the air duct and the outside, it is vulnerable The uneven wind can easily lead to unstable firepower in the furnace, which directly affects the combustion effect and leads to low thermal efficiency. In addition, the existing biomass combustion furnace is only used for boiling water and cooking, and its function is too single.

Contents of the invention

In order to solve the problems of low thermal efficiency and single function of the existing biomass burning furnace, the utility model provides a high-efficiency, energy-saving and environment-friendly biomass furnace.

The utility model is realized by adopting the following technical scheme: a high-efficiency, energy-saving and environmentally-friendly biomass furnace, including a furnace body with a furnace inside, a heat insulation layer outside the furnace, a charging door for feeding into the furnace, and a furnace above the furnace. There is a stove, with a grate under the hearth, an ash discharge drawer under the grate, a chimney connected to the stove on the furnace body, a cone-shaped burner between the hearth and the stove, and a vial on the outside of the burner inside the furnace. The air chamber communicates with the outside world. At least two rows of combustion-supporting holes communicated with the air chamber are provided on the side wall of the cone-shaped combustion-supporting device. Ring-shaped windshields, the number of ring-shaped windshields is equal to the number of rows of combustion-supporting holes, and there is a gap between two adjacent ring-shaped windshields.

In addition, a water jacket is arranged around the stove on the furnace body, a heating water tank connected with the water jacket is arranged around the chimney on the furnace body, and a water inlet pipe and an outlet pipe connected with the indoor heating are arranged on the heating water tank. While lighting a fire for cooking, it can realize small-area indoor heating.

Compared with the prior art, the utility model increases the number of combustion-supporting holes on the side wall of the combustion-supporting device, and arranges windshields around it. While increasing the air intake, the utility model evenly and uniformly enters the air so that the biomass can be fully burned. The firepower is enhanced and stable, which has the effect of saving energy, reducing consumption, and protecting the environment; and adding a water jacket and a heating water tank connected to the indoor heating, so that it can provide heating for indoor heating while boiling water for cooking.

The utility model has the advantages of reasonable structure, convenient use, high heat utilization rate, energy saving, good environmental protection effect, and can realize heat supply for indoor heating.
