Tangential inlet hybrid-tube-shaped flame burner

Abstract

The invention relates to a tangential inlet hybrid-tube-shaped flame burner. The burner comprises a burner body which is internally provided with a rotational flow mixing cavity and further comprises at least two airflow inlets communicated with the rotational flow mixing cavity in the tangential direction of the rotational flow mixing cavity. By means of the structure of the burner, fuel and an oxidizing agent are tangentially injected into a burning chamber and fast mixed and burned in the burning chamber, and the danger of backfire can be effectively prevented; meanwhile, due to the special rotational flow flowing characteristic, high-temperature fuel gas is wrapped by low-temperature unburned gas, wall face ablation of the burner can be effectively prevented, the service life of the burner is prolonged, and heat loss can be substantially reduced; by changing the size of gap blocks, the flow rate of the burner inlets can be changed flexibly, the mixing effect of the fuel and the oxidizing agent is changed, generation of soot and other pollutants is reduced, and the flame burner has the advantages of energy conservation and emission reduction.

Description

Technical field [0001] The invention relates to the field of combustion, in particular to a tangential inlet mixed tubular flame burner. Background technique [0002] The current burning of fossil fuels provides about 80% of the energy for social production and life. The environmental pollution caused by its emissions has seriously affected people’s daily lives. How to use existing fossil fuels more safely and effectively and develop ultra-low pollution The economical and environmentally friendly energy technology for waste has become the focus of increasing attention. [0003] The environmental pollution caused by the emission of combustion pollutants, such as haze and climate warming, has always plagued human beings. Scholars from various countries are also actively studying various combustion technologies to solve the problems of pollutant emission and energy consumption. In recent years, the oxy-fuel combustion technology with higher combustion efficiency has received widespr...

AI Technical Summary

Problems solved by technology

In recent years, oxygen-enriched combustion technology with high combustion efficiency has attracted extensive attention due to its advantages of high temperature, less pollutant emissions, and low cost of greenhouse gas recovery and utilization. In the case of high temperature, it is easy to cause tempering, and in the case of serious tempering, there is even a danger of explosion

In addition, when the existing combustion technology burns under the condition of high oxygen concentration, it releases a lot of heat and the temperature of the gas is high, which is not conducive to the long-term operation of the burner; at the same time, the combustion is violent and the flame is unstable under high oxygen concentration. Very limited in practical applications
