Glass furnace flue gas waste heat power generation As a major energy consumer in building materials industry, glass production needs to consume large amounts of energy, glass melting furnace design using heavy oil, natural gas, coal gas and other fuels. The combustion of the fuel in the furnace of heat release, the glass liquid absorption of total calories 35~40%; through the furnace surface heat loss is 20~25%; the smoke loss for 30~40%. Visible glass furnace flue gas away a lot of heat, so the flue gas heat recovery potential, effective utilization of waste heat in glass production has become an effective way to reduce the comprehensive energy consumption of glass production. Utilization of flue gas waste heat resource is mainly heat utilization and power recovery two. At present, the glass industry mainly uses the recycling pathway heat utilization, namely in the kiln tail is provided with waste heat exchange device, half through the flue gas waste heat exchange device, to produce saturated steam waste heat utilization of flue gas, used for the production and life, which is mainly used for the production of heavy oil heating, but required the use of steam and is small, and the use of natural gas as fuel for glass production line, its production is almost without steam, so the waste heat of the flue gas have not been fully utilized. Since 2004, China International Building Materials Engineering Co. Ltd. the gas-fired combined cycle, various industrial kilns (cement industry, metallurgy industry, chemical industry) experience waste heat power generation technology and equipment, waste heat power generation technology developed characteristics suitable for glass kiln flue gas waste heat. Using the technology of comprehensive utilization of the waste heat of flue gas at the same time, we can not only reduce purchased electricity, improves the utilization ratio of energy, but also can reduce emissions of atmospheric pollutants, reduce the greenhouse effect 1, technol
