Rankine and Brayton Cycle Cogeneration for Glass Melting
Abstract
Comparisons are made of the performance and installation costs of Rankine and Brayton power cycles when applied to waste heat recovery from a 350 ton/day container glass furnace. The power cycles investigation included: a) a conventional steam Rankine cycle, b) an organic Rankine cycle, c) an indirectly heated positive pressure Brayton cycle and d) a directly heated subatmospheric Brayton cycle. For the specified flue gas temperatures considered, the organic Rankine cycle produced the most electric power. If, however, reduction in fuel cost is of primary importance, then simple heat recuperation is the most effective method of heat recovery. Except for the subatmospheric Brayton cycle, typical payback periods are on the order of three to four years. The subatmospheric Brayton cycle was found not to be an attractive heat recovery alternative for this particular application.
