Abstract
A waste heat boiler system includes a vertically elongated waste heat boiler having an upper portion with a waste gas inlet and a lower portion with an exhaust line connection which in addition to its vapor generating tubes includes evaporator tube nests and a water preheater. The waste gases are received from a dry coke cooling vessel and they are delivered through a separator by a blower to the lower end of the coke cooling vessel for flow upwardly through the hot coke. The superheater is mounted over the waste heat boiler and has a connection through a controllable valve to the top of the waste heat boiler. The superheater includes its own burner and air and external gas supply are supplied to the combustion chamber for the superheater along with bypass portion of the circulated waste gases. The steam generated by the boiler is delivered from a steam cylinder or drum in the superheated tubes of the superheater. Some of the gases from the superheater are selectively delivered to the waste heat boiler and some are discharged through atmosphere.
