API 521 SRU REACTION FURNACE WASTE HEAT BOILER

SURE™ Double Combustion | BOConline UK

There is no sulphur condenser between the first waste heat boiler (WHB), and the second reaction furnace. Also, there is no burner in the second reaction furnace. By design, the gases exiting the first waste heat boiler and entering the second reaction furnace are substantially above the auto-ignition temperature of hydrogen sulphide and sulphur vapour, under all normal and turn-down operation
