APPLICABILITY EVALUATION AND DEMONSTRATION OF DOMESTIC GAS APPLIANCE USING NATURAL GAS–HYDROGEN MIXTURE

Hydrogen as one of the most potential clean energy has the advantageous characters of fast combustion rate and high conversion efficiency. It can be mixed with natural gas used as industrial, commercial or domestic fuel. Many countries in the world have developed plans to apply natural gas–hydrogen mixture for residential users and carried out demonstration verification. Based on theoretical analysis and calculation of combustion characteristic parameters of natural gas–hydrogen mixture, this work investigated the adaptability and safety of domestic gas appliances using natural gas–hydrogen mixture by referring to the corresponding national standards, so as to analyze the proportion of domestic gas appliances hydrogen blending that can bear without any adjustment through experimental tests.
