The collection and utilization of fermented biogas are becoming more and more important, and as the gases come from waste fermentation, the use and consumption of the fermented biogas belong to renewable energy sources, not only can replace non-renewable fossil fuels, but also can reduce the emission of greenhouse gases.

However, in the fermentation biogas treatment and utilization system, because of the mismatch between the produced gas and the used gas, it is often necessary to provide an incinerator to burn off the surplus gas intensively. In addition, since the sewage with high pollution concentration is discharged in the waste treatment process, the sewage is changed into "leachate" in a landfill, and the leachate is treated by using gas combustion generated by waste fermentation, so that the novel treatment mode of treating waste by waste is adopted. Biogas burners have been developed on this basis. Traditional biogas utilization is generally used as household fuel gas, and a corresponding burner, namely a kitchen range, is already a common combustion device, but no mature application exists at present for a large number of burners required in a gas burning or percolate burning evaporation process.
