FLAMMABLE GAS CONCENTRATION SYSTEM

摘要

A flammable gas concentration system is provided with a concentrating means (10), which takes at least a part of a product gas (PG), concentrates a flammable gas included in the taken product gas (PG) and generates a high concentration gas (CG). The system is also provided with a mixing means (2), which takes the high concentration gas (CG) generated by the concentrating means (10) and a material gas (IG), and mixes the taken high concentration gas (CG) with the material gas (IG) to generate the product gas (PG).
