Abstract
A deflector means having a trapezoidal cross section for reducing erosion of heat exchanger tubes caused by a flowing, particle-laden combustion gas produced in a fossil fuel-fired boiler, and a draft loss reduction means for use in connection with the deflector means. The deflector means preferably is attached to heat exchange tubes in a first row of a tube bank so as to precondition the combustion gas flow. The draft loss reduction means preferably is affixed to heat exchange tubes in a second row of a tube bank in order to reduce draft loss typically caused when combustion gas flows around heat exchange tubes.
