Abstract

A heat exchanger for heat exchange between a first and a second fluid and comprising a cylindrical casing 2 , a cylindrical fluid conduit 5 arranged inside the casing such that an axially extending tubular space 8 is defined, at least one helical coil 9, 10 of a finned or corrugated tube being arranged inside the tubular space, and adjustable throttle means 17, 17 a , 18 adapted and arranged for adjustably throttling flow of the first fluid through the conduit 5 to adjust the flow of the first fluid through the conduit and the first tubular space for adjusting the heat exchange between the first fluid and the second fluid flowing through the helical coils 9, 10.

Description

technical field [0001] The present invention relates to a heat exchanger for exchanging heat between a first fluid and a second fluid, comprising a substantially cylindrical housing with a first inlet and a first outlet so that the first fluid is substantially Axial direction flows through the housing, and at least one helical coil disposed inside the housing as a fin or wave tube. Background technique [0002] Heat exchangers of this type are known in which the first fluid is forced out or in from inside the coil. The heat transfer from the first fluid to the second fluid within the coil is not well controlled and therefore not the most efficient. Contents of the invention [0003] It is an object of the present invention to provide such a heat exchanger in which the flow of the first fluid, for example the flow of exhaust gas from natural gas-fueled turbines, internal combustion engines, furnaces, burners, incinerators, etc., is controlled in a controlled manner around ...
