Abstract

The invention relates to a combustion device with the ultra-low deviation equivalence ratio and a method. The device comprises a primary fuel channel which is located at the central position of the combustion device with the ultra-low deviation equivalence ratio, a primary air channel which surrounds the primary fuel channel and is coaxial with the primary fuel channel, a secondary air channel which is located on the radial outer side of the primary air channel and is coaxial with the primary air channel and a secondary fuel channel which comprises a plurality of pipelines which are arranged in the secondary air channel and are uniformly distributed around the primary fuel channel; the primary fuel channel and the primary air channel are arranged in a manner that the primary air flow is excessive relative to the primary fuel injection amount, so that low-oxygen-concentration combustion-supporting air is generated through combustion; the secondary fuel channel and the secondary air channel are arranged in a manner that the secondary fuel injection amount is excessive relative to the secondary air flow, and therefore low-calorific-value secondary fuel is generated through combustion.The device is further provided with a burnout area for mixed combustion of low-oxygen-concentration combustion-supporting air and low-calorific-value secondary fuel.

Description

technical field [0001] The invention relates to the technical field of gas clean combustion, in particular to an ultra-low nitrogen combustion device and a combustion method deviated from the equivalence ratio. Background technique [0002] Nitrogen oxides (NOx) produced during gas combustion are one of the main air pollutants, and the country's emission limits for nitrogen oxides are increasingly tightened. In recent years, the mainstream flue gas external circulation (FGR) low nitrogen burner can basically meet the emission of 30mg / Nm 3 However, the flue gas external circulation type low-nitrogen burner needs the flue gas external circulation to account for about 15-20% of the total flue gas volume, reducing the boiler efficiency by 2%-4%, resulting in energy waste, and there is no further The ability to reduce nitrogen oxides cannot meet the tightening expectations of national policies. The flue gas internal circulation (FIR) low-nitrogen burner has also been developed ...
