Abstract
A high temperature plate heat exchanger with low chromium rejection for fluids above 550° C. and a method of cooling a gas is suggested. The heat exchanger comprises a plurality of heat transfer plates made of a chromium-containing alloy, particularly high-temperature stainless steel or Ni-based chromium-containing alloy and having two heat transfer surfaces. The plurality of heat transfer plates comprise at least on one heat transfer surface of the heat transfer plates a chromium absorber coating comprising porous titanium dioxide over at least a first portion of the length of said heat transfer surface. The chromium absorber coatings of two adjacent heat transfer plates are facing each other.
