Straw briquette gasification dual-swirl burning furnace

Abstract

The invention relates to a straw briquette gasification dual-swirl burning furnace, which is a high-efficient and clean burning device. A furnace body is divided into an upper part and a lower part which are a burning chamber and a gasification chamber respectively, the lower gasification chamber can convert solid fuels such as straw briquettes and the like to combustible gas which is further mixed with primary wind and secondary wind in the swirl burning chamber for burning, then the mixture can rotatablely enter a secondary burning chamber for full burning, the residence time of flames in afurnace chamber is long, and the heat exchange is sufficient; additionally, the device is further provided with an energy-saving water tank which can fully absorb heat contained in flue gas exhaustedby the furnace chamber, thereby utilizing the heat energy to the maximum extent. The furnace is characterized by rapid start-up speed (fuel gas can be generated at about 15 minutes after the first ignition and the fuel gas can be generated for only 3-5 minutes after the re-start after furnace is banked up), good furnace banking-up performance (no fire extinguishment within 24 hours), high fuel gasification rate of being more than 75%, full burning of the fuel gas, no production of secondary pollution such as tar, fly ash and the like, high temperature of the furnace chamber and ability of meeting the requirements of Chinese cooking.

Description

Technical field: [0001] The invention relates to a straw briquette gasification double-swirl combustion furnace, which is a high-efficiency and clean combustion device for converting "straw briquette" solid fuel into gas fuel. Background technique: [0002] "Straw briquetting" as a substitute for civilian briquettes, there are still unsafe factors such as tar secondary pollution during combustion and use, fly ash pollution caused by feeding and ash cleaning, insufficient combustion, and CO leakage after the furnace is closed. In recent years, the research and development of "straw briquette" clean and safe combustion devices have appeared one after another, but there are still many products that are not satisfactory, such as: low gasification efficiency, insufficient combustion of gas, insufficient firepower, and it is difficult to meet the needs of Chinese cooking Wait. Invention content: [0003] In order to overcome the defects of the prior art, the object of the prese...
