fire water tube 6 ton coal fired steam boiler
boiler modle :DZL6-1.25-AII
⑴, uses arched tube plate and threaded pipe consisting of drum, so that the steel drum by the quasi- elastic structural body becomes subject to the abolition of the bracing piece tube sheet area , reducing the stress . Smoke tube tube plate consists of two return to single return , solve the problem of tube sheet cracks .
⑵, the lower part of the drum rise due to the arrangement of the discharge tube , eliminating dead zones at the bottom of the drum , so that deposition of sludge is not easy , the drum can get a good high-temperature cooling zone , preventing the lower portion on drum .
⑶, threaded pipe using efficient heat transfer , heat transfer enhancement effect is obtained , to the boiler temperature and pressure and fast to improve the thermal efficiency of the boiler.
⑷, compact structure, compared with the same type of boiler , outside of a small size , saving boiler room investment in infrastructure .
⑸, stable operation, easy adjustment, contribute enough . With 110% overload capacity.
⑹, using threaded pipe heat transfer enhancement , improved heat transfer coefficient and thermal efficiency , because there are disturbances in the flue pipe . Smoke tube hard fouling , played the role of self- cleaning .
