Abstract
A heat pipe air preheater includes a multiplicity of heat pipes arranged in a plurality of superposed planar rows inclined relative to the horizontal, the rows of heat pipes including a first group of rows inclined at a first inclination angle and a second group inclined at a second inclination angle. Means are provided for removing collections of soot or other particulate matter from the evaporator ends of the heat pipes, the rows of the first group being disposed on one side of these means while the rows of the second group are disposed on the other side, the rows of the two groups converging in the direction of the heat pipe condenser ends.
