气源改造1 1　我公司一直沿用燃点温度和热值很高的氢氧焰进行烧熔压封 ,氢氧焰温度达 2 80 0ｋ。点火后 ,扩散面较大 ,为避免面部烧烤 ,距离稍大 ,操作不方便。氢气的渗入或泵表面的附着会导致管压升高、启动困难 ,甚至造成自熄。液化石油气热值 :10 0 5× 10 7Ｊ ｍ3 ,密度 Gas source reform 1 1 Our company has been using the ignition temperature and high heat value of hydrogen and oxygen flame burning seal, hydrogen flame temperature of 2 80 0k. After ignition, diffusion surface larger, to avoid facial barbecue, slightly larger distance, inconvenient operation. Hydrogen infiltration or pump surface attachment leads to increased tube pressure, difficult start-up and even self-extinguishing. Liquefied petroleum gas heat value: 10 0 5 × 10 7J m3, density
