A special burner for high temperature biomass gas

Abstract

The invention belongs to the technical field of efficient biomass energy utilization, and particularly relates to a special high-temperature biomass gas combustor. The special high-temperature biomass gas combustor comprises a first pipeline. The first pipeline comprises two layers, the outer layer is a first combustion improver pipeline, the inner layer is a gas pipeline, and an interval for a first combustion improver to pass is arranged between the outer layer and the inner layer. An ignition device is arranged in the gas pipeline. The first pipeline is sleeved with a second pipeline. An interval is formed between the side wall of the first pipeline and the side wall of the second pipeline. The length of the first pipeline is smaller than that of the second pipeline. An air inlet is formed in the right end of the first pipeline, and an air outlet is formed in the left end of the first pipeline. One end of the second pipeline is of a sealed structure and is fixedly connected with the air inlet of the first pipeline. The side wall of the second pipeline communicates with a gasification furnace through a pipeline. The second pipeline is further sleeved with a closed first cavity. The exterior of the first cavity is connected with a second combustion improver pipeline, and the second pipeline is provided with a plurality of through holes communicating with the first cavity. By means of the special high-temperature biomass gas combustor, the length and the temperature of flames can be adjusted, running is stable and reliable, and few pollutants are discharged.

Description

technical field [0001] The invention belongs to the technical field of high-efficiency utilization of biomass energy, and in particular relates to a special burner for high-temperature biomass gas. Background technique [0002] With the development of technology and the enhancement of people's awareness of environmental protection, people no longer directly burn biomass to obtain heat, but convert biomass into gas as fuel. Biomass gasification is to convert various crop straws and wood processing residues Raw materials such as industrial organic waste and industrial organic waste are converted into biomass gas through a dedicated biomass gasifier to improve biomass utilization efficiency; during the conversion process of the gasifier, its outlet temperature reaches above 400 ° C, and contains a large amount of solid particles and High-boiling point organic components, such as tar, wood vinegar, etc., in order to remove the above substances, people often use cooling and dust ...

[0002] With the development of technology and the enhancement of people's awareness of environmental protection, people no longer directly burn biomass to obtain heat, but convert biomass into gas as fuel. Biomass gasification is to convert various crop straws and wood processing residues Raw materials such as industrial organic waste and industrial organic waste are converted into biomass gas through a dedicated biomass gasifier to improve biomass utilization efficiency; during the conversion process of the gasifier, its outlet temperature reaches above 400 ° C, and contains a large amount of solid particles and High-boiling point organic components, such as tar, wood vinegar, etc., in order to remove the above substances, people often use cooling and dust removal purification technology for treatment, but in the process of using cooling and dust removal purification technology, the sensible heat in the gas and the tar wood vinegar The heat cannot be fully utilized, resulting in a large amount of heat loss; therefore, a dedicated gasifier burner is required for combustion. The traditional gasifier burner is a common equipment for burning high-efficiency gas. The traditional burner only has two gas supply pipes, namely Fuel pipelines and combustion aid pipelines, because the gas discharged from the gasifier is mainly CO, hydrogen, methane and other mixed gases, and a large amount of water vapor is also generated in the initial gas production stage in the gasifier, it is difficult to use a common ignition device Ignite it, causing a large amount of gas to be discharged into the air, causing environmental pollution. In the process of gas combustion, the problem of unstable gas production often occurs, causing the ignited flame to go out, resulting in fire failure and ceasefire, resulting in many Big inconvenience, so the existing technology needs further improvement
