Abstract
The present invention relates to an apparatus for heat transfer from hot particulate laden gas to a coolant fluid within a heat transfer tube. The apparatus is comprised of layers of vertically aligned strips which are offset at an angle to adjacent layers and form channels which extend through the layers. Heat transfer tubes are located in the channels formed by the vertically aligned strips. The hot particulate laden gas introduced into the apparatus is divided into a number of streams moving in two different directions by the layers of vertically aligned strips. The streams of gas cross each other spatially and thus generate vortices. The vortices force the particles away from the heat transfer tube in the center of the channel and to precipitate on the vertically aligned strips where they fall due to gravitational forces or are removed by a shaking apparatus. Heat is then drawn from the resulting substantially particulate free gas.
