Unlike natural gas, the main component of low heating value gaseous fuels is often an inert gas such as nitrogen, carbon dioxide or water vapor. Wherein the concentration of combustible components (such as carbon monoxide or hydrogen) is usually only about 25% by volume, the calorific value is very low, a small part of combustible components generally enter an industrial kiln for combustion, the rest combustible components are directly ignited by a torch and discharged into the atmosphere, and the concentration of nitrogen oxides generated by the two modes is higher.
As a key device for fully utilizing low-heating-value gas fuel, the research on domestic low-heating-value gas burners is mostly focused on the aspect of improving the performance of the burners, and the attention on the aspect of controlling the atmospheric pollutants is less. With the successive departure of the latest atmospheric pollutant emission standards across the country, the latest emission requirements cannot be met by the traditional low-calorific-value gas burner alone, and the modification of the existing furnace type inevitably involves the problem of matching the sizes of the new burner and the old furnace chamber, so that a novel low-calorific-value gas low-nitrogen burner needs to be developed to meet the latest emission requirements and the boiler performance requirements at the same time.
