Abstract
A skewer system comprises a skewer rod that holds tires in suspension during an incineration process where the tires are burned for fuel in a kiln such as a cement kiln or a lime kiln. In certain implementations, the skewer system also comprises a fuel advancing system to advance tires loaded onto the skewer rod into the heated gas in a stationary heat transfer station of the kiln. In further exemplary implementations, the skewer system comprises a mechanism to recover wire remnants from incinerated tires, the wire can be cut off the skewer and dropped into the kiln, or the wire itself can be burned off.
Claims20
A solid fuel delivery system that delivers solid fuel into a stationary heat transfer station of a kiln, comprising:
- a skewer rod having a first end and a length such that when the solid fuel delivery system is installed on the stationary heat transfer station of the kiln:
- the skewer rod is utilized to suspend solid fuels in a heated gas stream flowing through the stationary heat transfer station of the kiln;
- and
- the first end of the skewer rod is positioned outside the stationary heat transfer station and the length extends into the stationary heat transfer station;
- and
- a fuel advancing system having a ram that advances solid fuel along the length of the skewer rod, wherein the solid fuel transitions into the heated gas stream flowing through the stationary heat transfer station of the kiln;
- wherein the skewer rod restrains the solid fuel from detaching therefrom in response to force on the solid fuel generated by the heated gas stream.
A method of delivering solid fuel into a stationary heat transfer station of a kiln, comprising:
- implementing an automated cycle comprising:
- automatically loading solid fuel onto a skewer rod having a first end and a length by skewering the solid fuel onto the first end of the skewer rod;
- and
- advancing the solid fuel along the skewer rod into a stationary heat transfer station of the kiln such that the skewer rod suspends the loaded solid fuels in a heated gas stream flowing through the stationary heat transfer station and the skewer rod restrains the solid fuel from detaching therefrom in response to force on the solid fuel generated by the heated gas stream;
- and
- controlling the automated cycle to cycle a programmed amount of the solid fuel onto the skewer arm at a set rate.
