Combined sulphur burning furnace and boiler.

摘要

A combined sulphur burning furnace and water-cooled boiler arrangement for producing a cooled, gaseous sulphur dioxide-air mixture in which the furnace (14) is located below the boiler tubes arrangement (25) in a vertical, cylindrical shell (11). The hot gases produced in the furnace exit axially (17) into an upper chamber (28) defined by the water-tube arrangement (25) and pass through the cooling water-tube arrangement in radial outward flow to an outer chamber (25) provided with cold-side by-pass control means (32) and then exit the shell (33). The apparatus provides for savings in ducting, foundations, piping and the like; and permits more efficient sulphur burning and cooling.
