There is a relatively special once-through steam boiler in the steam boiler, which is actually a steam generating equipment for steam production in which the medium passes through each heating surface at one time and there is no forced flow of circulation. Fra denne typen spesielle arbeidsmetoder er den en gang gjennom dampkjelen annerledes. Hva er hovedfaktorene?
When the once-through steam boiler is in operation, the medium in the evaporation heating surface will have a pulsating state, and its flow rate will change periodically with time; I tillegg er de hydrodynamiske egenskapene flervurderte. I tillegg er trykkhodet på den en gang gjennomgående tapet av dampkjelen også veldig stor.
During the start-up process, in order to reduce the heat loss and medium loss of the once-through steam boiler, a bypass system should be installed as much as possible. Fordi den en gang gjennom dampkjelen ikke har noen damptrommel, kan varmeprosessen være raskere, så oppstartshastigheten vil være raskere.
If you compare the once-through steam boiler with the natural circulation boiler, the heat exchanger, superheater, air preheater, combustion system, etc. in the structure of the two are completely different. For kontinuerlig å forbedre kvaliteten på dampen, kan metoden for ekstern overgangssone og dampvannsseparator velges.
