Waste heat recovery boiler in glass industryGlass industry consumers huge energy every year. China has a toplevel of thefoatglassprocessingindustryintheworld, howeverhereisstill abiggapbetweentheinternational level onenergyconsumption. The foat glass kiln waste heat power generationsystemcanfurther theutilizationof thewasteheat morethan!",so the waste heat can be almost fully used.
