微正压锅炉与负压锅炉相比有炉体小、结构简单、过剩空气系数低等特点,因而在快装工业燃油锅炉方面获得了广泛应用。我国目前所产的2t/h、4t/h、6t/h、10t/h工业燃油锅炉几乎均毫无例外地采用了微正压燃烧方式。但是,积本人在大庆油田十几年的工作实践,感到微正压燃油锅炉的门孔密封是值得引起注意的问题,尤其是防爆门的密
Compared with the negative pressure boiler, the micro-positive pressure boiler has the advantages of small furnace body, simple structure and low excess air coefficient. Therefore, the micro-positive pressure boiler has been widely used in the fast-loading industrial oil-fired boiler. China’s current production of 2t / h, 4t / h, 6t / h, 10t / h industrial oil-fired boiler almost without exception, the use of micro-positive pressure combustion. However, plot their own work in Daqing Oilfield more than 10 years, I feel that the micro-positive pressure oil-fired furnace door seal is a cause for concern, in particular, the explosion-proof door close
