ABSTRACT:
This invention has an object of providing a compact and inexpensive apparatus and method of combustion for a pipestill heater which enjoys high thermal efficiency insusceptible of the restriction imposed by either the inlet temperature of the process fluidor the magnitude of the allowable pressure drop in the coil, incurs only a sparing possibility of polluting the environment, and produces only a petty pressure fluctuation in the combustion chamber.
In the pipestill heater of this invention, the combustion devices which are disposed so as to confront the combustion chambers of the furnace are each provided with an air permeable heat accumulator made of a refractory material and a duct part having an oxidizing agent supply path and an exhaust gas discharge path formed therein, whereby the oxidizing agent for combustion is heated with the exhaust gas through the heat accumulator by virtue of the relative rotation of the heat accumulator and the duct part with rotating means.
