STEAM HEAT EXCHANGER - HANAMURA MASAAKI

Title:

STEAM HEAT EXCHANGER

Document Type and Number:

WIPO Patent Application WO/2007/058256

Kind Code:

A1

Abstract:

This invention provides a steam heat exchanger (1) provided with a steam heating pipe (4) comprising a heat transfer pipe part (11) with condensation and a heat transfer pipe part (12) with sensible heat provided on the lower side of the heat transfer pipe part (11) with condensation. In the heat transfer pipe part (11) with condensation, a liquid as a heating object is heated by latent heat. The drain discharge capacity in a steam trap (8) or an orifice (13) disposed on the drain discharge side is set so as to be equal to the amount of condensation at the service temperature of the steam heat exchanger (1). Condensed water produced after the heat exchange in the heat transfer pipe part (11) with condensation enters the heat transfer pipe part (12) with sensible heat on the downstream side to hold the heat transfer pipe part (12) with sensible heat in a water sealed state. In this heat transfer pipe part (12) with sensible heat, the liquid as the heating object is heated by sensible heat. By virtue of heat exchange by taking advantage of latent heat and sensible heat, the heat exchange efficiency is improved, the amount of steam used can be reduced, and the load of a steam generation source can be reduced.
