系统节能理论在水玻璃行业中节能改造的应用实例

Application Example of Energy-saving Reform of System Energy-saving Theory in Sodium Silicate Industry

制造水玻璃的燃料目前多采用气体燃料,气体燃料以水煤气为主,由于环保原因,大多数水玻璃生产企业正在逐步的将原有使用煤气改造为更清洁、高效的天然气。本工艺采用优化的自控方案,利用高热值、清洁的天然气作为燃料,对生产过程中水玻璃窑炉产生的烟气余热资源进行回收利用,并采用蒸汽蓄热器稳定蒸汽管网压力,合理高效的利用余热资源,以实现生产的高效、平稳、安全、节能的运行。

Fuel gas is offen used in the industry of manufacturing sodium silicate,since fuel gas is given priority to with water gas,most of the sodium silicate production enterprises are gradually transform the original used gas for cleaner,more efficient natural gas for environmental reasons. This process adopts the optimized control scheme to use the waste heat resources reasonably and efficiently,such as using high calorific value and clean natural gas as the fuel,recycling flue gas waste heat resources in the production process of sodium silicate furnace and stabilizing the pressure of the steam piping network with a steam thermal storage in order to realize the operation of smooth,safe,efficient and energy saving production.
