Abstract
Proper reheat gas temperature is maintained in a sulfur plant operation at a high turn-down ratio by providing parallel flow paths in the boiler and withdrawing portions of the hot products from each of the flow paths and mixing with first condenser effluent to bring the gas to reaction temperature. This maintains the optimum temperature and flow rate of reheat gas at high turn-down ratios.
