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. Remiantis tokiu specialiu darbo metodu, kadaise peržiūra garo katilas yra skirtingas. Kokie yra pagrindiniai veiksniai?
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; Be to, hidrodinaminės charakteristikos yra daugialypės. Be to, kadaise praeities garo katilo praradimo siurblio slėgio galvutė taip pat yra labai didelė.
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. Kadangi kadaise per garų katilas neturi garo būgno, šildymo procesas gali būti greitesnis, todėl jo paleidimo greitis bus greitesnis.
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. Norint nuolat pagerinti garo kokybę, galima pasirinkti išorinės pereinamosios zonos ir garo ir vandens separatoriaus metodą.
