Abstract
The disclosure describes wall for a direct fired heater which burns high sulfur fuels. The wall includes an inner casing lined internally with refractory and an outer casing spaced from the inner casing to provide, air space therebetween and means for controlling the rate of air flow thru the space. Proper selection of the refractory and proper control of the rate of air flow assure that the temperature of the inner casing is maintained above the dew points of sulfur oxides for any ambient condition. The casings are joined at their upper ends and an air opening is provided at the lower end of the outer casing whereby air is admitted to the air space. An adjustable air vent is provided at the upper end of the outer casing for control of casing temperature, when necessary. A plurality of horizontal baffles extend from the inner casing outward into the air space to inhibit re-circulation of air in the air space.
