  • Apparatus for heating up a chamber of a coking battery
    Patent number: 4190497
    Abstract: After replacement of the walls of one chamber of a coking battery this one chamber is heated up by withdrawing relatively hot air from another still-hot chamber of the coking battery and injecting it into the cold chamber. This is done by means of a conduit extending between the two chambers and provided with an internal nozzle that conducts the hot gas from the hot chamber to the cool chamber by jet-pump action. This hot gas is mixed with relatively cool air so as slowly to heat the cool chamber up.
