Description
近年、副生ガスの漏洩による火災、爆発事故、人災などが多発しており、設備のメンテナンスもさることながら、漏洩に対する簡便かつ正確な早期発見技術へのニーズが高まっている。
混入するメタンガスの量、すなわち濃度は、検出装置の感度、すなわち測定下限値以上であればよいわけであるが、確実な検出のため、下限値の10倍を目標とするのが望ましい。また混入の上限は、漏洩検知の観点からはとくに制約はないが、メタンガスのコストや、ガスカロリー上昇による使用先のバーナ能力等を考慮して決めるのがよい。
3.35MJ/Nm3(800kcal/Nm3)の高炉ガス中に、41.7MJ/Nm3(9950kcal/Nm3)、メタン90vol.%の都市ガスを混入させる場合、高炉ガス1000Nm3に対して都市ガスは1.1Nm3とすればよい。これによりガスカロリーはわずかに上昇して3.39MJ/Nm3(810kcal/Nm3)程度となるが、実用上ほとんど影響はない。
