Reducing GHG and NOx Pollutant Emissions with an Oxy-Hydrogen Burner

The paper presents experimental results obtained by authors in testing an own conception burner operating with a biofuel (hydrogen) and technical oxygen as a supplier of oxygen for combustion. The objective of the work is to create an equipment for producing thermal energy for industrial heating furnaces under conditions of complete  elimination of greenhouse gas emissions GHG (mainly CO2) and significant reduction of NOx (NO2 and NO) emissions by using the most advanced known techniques. The hydrogen and oxygen staged mixture method is applied, which allows to self-cooling the flame to reduce the NOx emissions. Also, hydrogen is used uniquely without other fossil fuels in mixture and oxygen in the form of technical oxygen without being component of a combustion air even enriched in oxygen. The result of stand testing showed that the burner operation is stable without explosion danger in the thermal power range 14.85-30 kW, the CO2 and CO emissions are zero and the NO2 and NO emissions are relatively low below the maximum limits allowed in the world. The tested technical solution is optimal for the burner operation and meets the objective, but additional tests and verifications are still required for industrial application.
