The performance of burner largely determines the reliability of low calorific value gas combustion equipment, and its low carbon performance is an important basis for market competitive advantage. At present, there are several mature low nitrogen combustion technologies in the industry:
Fuel grading combustion technology is also known as three - stage combustion technology or re-combustion technology. Air and fuel are graded into the furnace to form an initial combustion zone, a recombustion zone and a burnout zone.
When the flue gas is recirculated, part of the low-temperature flue gas is directly sent to the combustion area, or mixed with the primary or secondary air and sent to the combustion area, which not only reduces the combustion temperature, but also reduces the oxygen concentration, and then reduces the NOx emission concentration.
Low excess air combustion is the combustion process as close to the theoretical amount of air as possible under the conditions, with the reduction of excess oxygen in the flue gas, can inhibit the reaction of nitrogen oxide precursor and oxygen in the flue gas, which is one of the simplest ways to reduce NOx emissions, can reduce NOx emissions by 15% ~ 20%. But at the same time, if the oxygen content in the furnace is too low, such as less than 3%, it may lead to incomplete combustion of gas, increase the content of CO or other combustibles in the flue gas outlet, and reduce the combustion efficiency.
