Abstract

The invention provides a fuel gas vortex combustion device with oxygen supplied for the front end. The fuel gas vortex combustion device comprises a pot rack which is arranged on the top of an oven outer shell, and a refractory layer is arranged in the oven outer shell. A gas mixing cavity is arranged at the bottom of the oven outer shell, the side wall of the gas mixing cavity is connected with one end of a mixed gas pipe, and the other end of the mixed gas pipe is connected with an air inlet pipe and a gas pipe. One end of the air inlet pipe is communicated with the gas mixing cavity, and the other end of the air inlet pipe penetrates through the refractory layer to be communicated with an oven inner cavity. A banking fire plate is arranged in the middle of the oven inner cavity and located at the center of the bottom of the refractory layer through an adjustment screw rod. The distance b between the banking fire plate and the bottom of the refractory layer is not smaller than 80 mm and not larger than 300 mm, the area of the banking fire plate is one third to a half of the cross sectional area of the oven inner cavity, n small banking fire holes are evenly distributed in the banking fire plate, n is not smaller than 3 and not larger than 8, the diameter d of each small hole is not smaller than 5 mm and not larger than 20 mm, a secondary air inlet pipe is arranged under the banking fire plate, and the secondary air inlet pipe is connected with the air inlet pipe.

Description

technical field [0001] The invention relates to the field of biomass gasification and combustion, in particular to a front-end oxygen gas vortex combustion device. Background technique [0002] Biomass gasification technology is constantly developing, and it will have a huge potential impact on the production and life of human society. [0003] Biomass gasification gas is a gas with low calorific value, about 1100 kcal / M 3 Left and right, in order to achieve good heat energy utilization and environmental protection effects, full combustion and convenient application of gas are very important. [0004] Traditional biomass gasification gas combustion generally uses stoves made of infrared ceramic plates, which have problems such as inconvenient oxygen supply and gas distribution, low combustion temperature, and easy blockage of small holes in ceramic plates. It is necessary to invent a simple and practical device to burn biomass gasification gas to effectively solve the prob...
