ABSTRACT:
A microwave incinerator is configured to incinerate waste material. The waste material is installed within a microwave absorbing shroud located in a microwave chamber. The combination of low microwave heat input and a vacuum drawn on the chamber vaporizes the water in the garbage. During this first phase there is no combustion because of the relatively low temperature and the lack of oxygen. Once the material is dry, intense microwave energy is applied to the chamber heating the silicon carbide shroud to an elevated temperature in the range of about 500 to 1000 degrees C. Concurrent with the rapid rise in temperature, air containing oxygen is pumped into the chamber. The hot shroud ignites the material, after which heat is provided is a combination of combustion heat and microwave energy. The temperature is monitored and the microwave energy input is controlled to assure a controlled burn of the waste material.
