Problems solved by technology

[0002] Existing pellet combustion furnaces, such as barbecue ovens, use burners that are basically closed at the bottom. Ashes generated after the combustion of pellet fuels will accumulate at the bottom of the burner, and air inlets are set on the side walls of the burner to Air is fed in for combustion. During the combustion of pellet fuel, due to the continuous input of air into the burner, the ashes at the bottom of the burner will be blown up, causing the ashes to fly in the furnace body, and the ashes will stick to the food, which will bring bad results to the user. experience
Another example is the heating furnace, a grate is set on the bottom of the burner, and the air can be blown upward from the bottom of the burner, and the ashes will also be blown up and fly out through the chimney or the feeding port. If they fly outdoors, they will pollute the atmosphere. If it flies into the room, it is more likely to affect the air quality in the room

Embodiment 1

[0030] Such as Figure 1 to Figure 6 As shown, this embodiment provides a biomass combustion furnace, which includes a furnace body 1, a fuel hopper 6 is provided outside the furnace body 1, a burner 2 is provided inside the furnace body 1, and a feed port is provided on the side wall of the burner 2 201, the feed port 201 is connected to the bottom of the fuel hopper 6 through the feeding channel 104, the top of the burner 2 is open, the furnace body 1 is provided with an air intake channel extending to the bottom of the burner 2, and the bottom surface of the burner 2 is provided with a There is a grate 21 above the through opening for air intake and ash falling. The bottom of the furnace body 1 is provided with a water storage tray 3 and an ash receiving tray 4. The ash receiving tray 4 is located below the burner 2 and faces the through opening. mouth.

[0031] In this embodiment, a large area of ​​ash falling and air intake is realized through the through opening, so tha...

Embodiment 2

[0044] Such as Figure 7 to Figure 11 As shown, an auxiliary support body 214 for maintaining the primer is provided under the first layer of support body 211, the auxiliary support body is higher than the through opening, and the auxiliary support body 214 is located on the side below the feed port 201 and the range of setting does not exceed the grate 1 / 2 of the covered area, 1 / 2 here is just an approximate number, so as not to affect the normal dust fall and air intake. Adding the auxiliary support body 214 has two functions. On the one hand, in the state of high fire, it can reduce the ash falling efficiency and the air intake below the feed port 201, and the combustion efficiency of the pellet fuel at this position can be effectively controlled, so as to effectively avoid backfire. The occurrence of a fire situation, on the other hand, is to maintain the primer in a small fire state to avoid extinguishing. In this embodiment, the auxiliary support body 214 adopts a rod s...

Embodiment 3

[0051] In addition to setting two layers of support, you can also increase the number of layers on this basis, such as Figure 12 As shown, the grate also includes a third layer of support 215 fixed to the burner 2, the third layer of support 215 is higher than the second layer of support 212, between the third layer of support 215 and the second layer of support 212 There is a second channel 216, the width W2 of the second channel 216 is smaller than D, and the distance L3 between two adjacent third-layer supports 215 is larger than D and smaller than 2D. It can be understood that, according to actual needs, the number of layers of the support body can be increased.

Abstract

The invention discloses a biomass combustion furnace, belongs to the field of combustion equipment, and solves the problem of poor use experience caused by ash flying in a furnace body or flying into a room in the prior art. According to the technical scheme, the top end of a combustor is open, and a furnace body is provided with an air inlet channel extending to the bottom of the combustor; and a through opening used for air inlet and ash falling is formed in the bottom face of the combustor, a fire grate is arranged above the through opening, a water storage disc and an ash receiving disc are arranged at the bottom of the furnace body, and the ash receiving disc is located below the combustor and faces the through opening. The biomass combustion furnace is mainly used for effectively inhibiting ash flying and improving the combustion-supporting effect.
