尿素热解和水解技术在锅炉烟气脱硝工程中的应用

Application of the Urea's Pyrolysis and Hydrolysis Technology in Boiler Flue Gas Denitration

随着国内的经济发展,燃煤电厂锅炉烟气排放的指标控制越加严格,燃煤电厂烟气污染物的排放越来越受到国家和社会的广泛关注。锅炉烟气脱硫技术已在国内燃煤电厂全面实施,锅炉烟气脱硝技术在北京市已全面普及,在国内其它地方也逐渐推广,作为脱硝还原剂液氨的运用由于受到安全、地域等因素的限制,尿素热解和水解制氨技术逐渐受到青睐,将为许多用户提供选择。

The coal burning boilers＇ flue gas emission standard becomes stricter with Chinese economical development day by day.The government and the whole society pays more attention to coal burning power plants＇ flue gas emission.Desulphurization of the boiler＇s flue gas has been applied through the whole country.In city Beijing the denitration method has been applied widely.In other part of the country,transportation of the reducing agent liquid ammonia for denitration is still constrained due to safety and geographical reasons,therefore pyrolysis and hydrolysis of urea is,and it will be,still a popular method in use.
