Abstract
As a means not to use the external fuel for a heating source of pyrolysis drum, TAKUMA has developed such system that a part of pyrolysis gas generated due to pyrolysis of waste was burnt in a dedicated chamber as a fuel, and the high temperature air was generated through the indirect heat exchange with the combustion gas shown above, using the high temperature air heater, and such high temperature air was used for pyrolysis drum. It is possible to restrict the concentration of HCI to a low level, and to prevent the corrosion due to high temperature by burning the pyrolysis gas independently and further by using the combustion gas as a heat source of high temperature air heater. Besides, the method was also confirmed to provide the stabilized pyrolysis performance equivalent to that of conventional pyrolysis drum heating method in which the external fuel was used.
