DZ型燃煤锅炉由于其除尘效果差、污染严重,已被环保部门列为城市环境治理工作的重点。因此,大量DZ型燃煤锅炉将面临着停用或被改造的处境。目前,DZ型燃煤锅炉改烧煤气则成为治理污染重要途径之一。由于燃煤锅炉改烧煤气,锅炉的燃烧方式发生了根本性改变,所以,有诸多技术方面问题需要慎重考虑。1 DZ型燃煤锅炉改烧煤气基本要求DZ型燃煤锅炉改烧煤气从根本上改变了锅炉的燃烧方式。煤气是一种易燃、易爆的气体,对DZ型
DZ-type coal-fired boilers because of its poor dust removal effect, serious pollution, environmental protection departments have been listed as the focus of urban environmental governance. Therefore, a large number of DZ-type coal-fired boilers will face the situation of deactivation or transformation. At present, DZ-type coal-fired boiler to burn gas has become one of the important ways to control pollution. As coal-fired boilers to change gas, boiler combustion has undergone fundamental changes, therefore, there are many technical aspects that need careful consideration. 1 DZ-type coal-fired boilers to change gas basic requirements DZ-type coal-fired boilers to change gas radically change the way the boiler combustion. Gas is a flammable, explosive gas, on the DZ type
