Embodiment 1

[0035] A tubular furnace biomass burner, consisting of a silo, a feeding mechanism, a tubular furnace, and a slag discharge and slag breaking device. The top of the silo is provided with a detachable elongated cylinder (2), and the silo cover (1) Set on the top of the extended cylinder (2), the cylinder (3) is equipped with a hopper (4); the feeding mechanism includes a feeding shell (6), a feeding screw (7), and a feeding shell (6) Pass through the bellows (8) and moveably install at the outlet at the bottom of the hopper (4). The feed screw (7) is installed in the feed housing (6). The slag discharge device includes a slag discharge device with a hollow part. The slag-breaking screw (9) and the sprocket (10), the front section of the slag-discharging and slag-breaking screw (9) is solid, the middle section and the rear section are hollow, and the middle section is provided with an air inlet hole (10) communicated with the bellows (8). The rear section is provided with spir...

Embodiment 2

[0038] After the tubular furnace biomass burner described in this embodiment is started, the biomass fuel stored in the hopper of the silo enters the feeding shell through the hopper, and is pushed into the bottom of the inner sleeve of the tubular furnace by the feeding screw rod. The feed amount is controlled by the controller. After the initial feed amount is completed, the electronic igniter heats and ignites, and the air from the air supply system enters the tubular furnace through the bellows, and enters the bottom of the inner sleeve after being heated by the electronic igniter to ignite the biomass fuel. , after the biomass fuel is heated, through the primary oxygen supply and secondary oxygen supply of the distribution air system, the bottom drying, combustion, cracking and gasification, low-temperature combustion in the middle section, and high-temperature combustion process in the front section are realized in the inner sleeve, and then its high-temperature flame ...

Abstract

The invention relates to the technical field of biomass fuel burning, in particular to a biomass burning machine provided with a tubular furnace hearth. The biomass burning machine comprises a stock bin, a feeding mechanism, the tubular furnace hearth and a slag discharging and breaking device, and is characterized in that a detachable lengthened barrel (2) is arranged at the top of the stock bin, a stock bin cover (1) is mounted at the top end of the lengthened barrel (2) in a sleeving manner, and a hopper (4) is arranged in a barrel (3); the feeding mechanism comprises a feeding casing (6) and a feeding screw rod (7), the feeding casing (6) penetrates through a bellows (8) and is movably mounted at a bottom outlet of the hopper (4), and the feeding screw rod (7) is arranged in the feeding casing (6); and the slag discharging and breaking device comprises a slag discharging and breaking screw rod (9) provided with a hollow part as well as a chain wheel (10). The biomass burning machine provided with the tubular furnace hearth has the advantages of sufficient burning, low tail gas pollution, prevention of slag bonding and caking, wide biomass fuel adaptability, long service life, stable operation, low maintenance cost and the like.

Description

technical field [0001] The invention relates to the technical field of biomass fuel combustion, in particular to a tubular furnace biomass burner. Background technique [0002] At present, in order to cope with the increasingly prominent energy crisis, severe environmental pollution and climate change, countries all over the world attach great importance to the development and utilization of biomass energy. In some developed countries in the West, biomass energy has been widely used. In China, with economic development and increasing demand for energy, it is the general trend to develop biomass energy and increase the proportion of biomass energy in the energy structure. my country is also vigorously promoting the development of the biomass energy industry, and has introduced relevant encouraging and supporting policies. [0003] As a new type of fuel, biomass fuel is widely used in heating, hot water, industrial drying and other fields. Biomass fuel combustion technology ...
