家用燃气具对掺氢天然气的适用性评估与示范应用

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

氢能作为一种最具潜力的清洁能源,具有燃烧速率快和转化效率高等优点,可将其与天然气掺混作为工业、商用或民用燃具燃料使用。国际上多个国家相继制定天然气掺氢应用于居民用户的计划,并开展示范验证。本文基于掺氢天然气燃烧特性参数理论分析计算,并参照相应国家标准,通过实验测试的手段论证家用燃气具使用掺氢天然气的适应性和安全性,以此分析家用燃气具在不做任何调整的情况下可以承受的掺氢比例。

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.
