Large dynamic gasification combustion biomass burning machine

Abstract

The invention discloses a large dynamic gasification combustion biomass burning machine, and in particular, relates to the technical field of renewable energy. The large dynamic gasification combustion biomass burning machine comprises a horizontally arranged combustion chamber, a material transmission system and an air way system, wherein the material transmission system comprises a material box and at least one feed auger; a discharge port at the lower part of the material box is connected to the input end of the feed auger; the output end of the feed auger is connected with the combustion chamber; a water tank is arranged around the combustion chamber clinging to the outer wall, and is connected with a steam box; a rotating shaft at the output end of the feed auger extends and penetrates through the combustion chamber, and is fixed on a shell of the combustion chamber through a bearing base; the rotating shaft is a hollow shaft provided with a hole; one end of the hollow shaft is connected with a right air blowing pipe; the right air blowing pipe is provided with an air blowing port for blowing air into the hollow shaft; and the right air blowing pipe is communicated with the steam box through a steam pipe. The large dynamic gasification combustion biomass burning machine can enable fuels to be fully burnt, improves the burning efficiency, and prevents the environmental pollution caused by harmful gas discharged by insufficient combustion.

Description

technical field [0001] The invention relates to the technical field of renewable energy, in particular to a large-scale dynamic gasification combustion biomass burner. Background technique [0002] Biomass pellet fuel is a biomass solid shaped fuel with high efficiency, cleanliness, easy ignition, CO 2 With the advantages of near-zero emissions, it can replace fossil fuels such as coal and is used in civil fields such as cooking and heating, as well as industrial fields such as boiler combustion and power generation. In recent years, it has developed rapidly in the European Union, North America, and China; another major advantage of biomass fuels It can be applied to small boilers, hot blast stoves, and heating stoves, and realizes automatic ignition and continuous automatic combustion by using a pellet fuel combustion device. During the combustion process of the burner, the interior of the burner is generally positive pressure combustion. If the feeding device of the burne...

AI Technical Summary

Problems solved by technology

During the combustion process of the burner, the interior of the burner is generally positive pressure combustion. If the feeding device of the burner has smoke entering the feeding auger or even the material box during the feeding process, it will cause combustion backfire, resulting in incomplete combustion, causing burner unstable

[0003] The combustion devices in the prior art all use an auger device to send the pellet fuel from the hopper into the combustion chamber. The Chinese patent application number 201410765744.2 discloses a biomass pellet fuel burner, including a shell, a feeding system, a burner and The main fan, in which the conveying system includes a hopper machine connected to the outlet of the hopper, the auger is connected to the auger through a vertically arranged blanking channel, and the output end of the auger is connected to the burner , this kind of burner uses the uniform auger for stirring, and then uses the pusher auger set up and down for buffer feeding, which can provide the burner with balanced fuel and make the burner burn evenly. The settings of the material auger, the burner and the pusher are all directly connected, so that the sealing of the combustion chamber, the return auger and the material box cannot be guaranteed, causing the danger of tempering

On the other hand, the combustion chamber structure inside the existing burner is generally a cavity with an air supply port. After the fuel is pushed in, it only burns statically in the cavity. There is no structure for mixing the fuel evenly, which may easily cause insufficient combustion. Environmental pollution problems such as large smoke and dust emissions
