Osaka Gas has developed 1,400 models of industrial burners. With high burner energy efficiency provided by the high-performance control system we have developed, these burners are helping customers in a variety of industries and fields reduce their CO₂ emissions.
An outstanding example is the “Regenerative Burner System” we have developed and sold that can efficiently recover waste heat in industrial furnaces. In the “Regenerative Burner System,” two burners, each containing a heat storage vessel, alternate in combustion in intervals of less than a minute. When one burner is combusting, its exhaust goes out through the other burner's heat storage vessel. When the other burner combusts, for combustion air it uses the waste heat warmed up in the heat storage vessel. This allows it to obtain air heated to at least 1,000 degrees Celsius from 1,200 degrees Celsius exhaust and thus save approximately 50% in energy.
We are also developing natural gas burners for glass melting furnaces for manufacturing glass for bottles, automobiles, and construction materials, and more and more customers are adopting these burners as a way to dramatically reduce CO₂ emissions.
