Furthermore, a condensation drainage pipeline is connected to the lower portion of the condensation tank and communicated with the condensation chamber.

Compared with the prior art, the utility model discloses following beneficial effect has:

traditional indirect heating equipment is only negative pressure pipe of connecting on the condensate tank, and the comdenstion water directly sprays water cooling to steam in the condensate tank, the utility model provides a indirect heating equipment installs heat exchanger on the condensate tank, is provided with spiral winding pipe in the heat exchanger, uses negative pressure vacuum pump extraction steam, fully with steam and the contact cooling of heat exchanger inner wall. Compare traditional indirect heating equipment, the utility model discloses steam carries out the heat transfer back from the condensate tank, gets into heat exchanger again and carries out the heat transfer, and contact cooling pipeline area is big, can fully contact with the comdenstion water, and the cooling effect is better, because the steam after the condensation condenses into water and can follow the condensate tank and discharge, and the ponding that the condensate tank produced is few, greatly reduced drainage frequency, vacuum efficiency is higher.
