Abstract
A combustion kiln system, comprising: a pre-heating chamber which is supplied with waste product; and a combustion chamber which receives the waste product from the pre-heating chamber and in which the waste product is incinerated; wherein the pre-heating chamber heats the waste product to remove moisture from the waste product prior to transfer to the combustion chamber.
Claims13
A combustion kiln system, comprising:
- a pre-heating chamber which pre-heats supplied waste product;
- and
- a combustion chamber which receives the pre-heated waste product from the pre-heating chamber and in which the pre-heated waste product is incinerated;
- wherein the pre-heating chamber comprises a cavity through which the supplied waste product is displaced and includes a plurality of air inlets which feed heated air into the cavity of the pre-heating chamber and a plurality of vents through which a gas stream is vented, whereby the pre-heating chamber heats the supplied waste product prior to transfer to the combustion chamber, and
- wherein the combustion chamber comprises a cavity, a transfer mechanism which provides a grate at a floor of the combustion chamber and transfers the pre-heated waste product through a combustion zone, and a plurality of air supplies which supply air to the cavity of the combustion chamber.

A method of incinerating waste product, comprising the steps of:
- pre-heating supplied waste product in a pre-heating chamber;
- wherein the pre-heating chamber comprises a cavity through which the supplied waste product is displaced and includes a plurality of air inlets and a plurality of vents through which a gas stream is vented;
- feeding heated air into the cavity of the pre-heating chamber through the air inlets:
- transferring the pre-heated waste product from the pre-combustion chamber to a cavity of a combustion chamber, wherein the pre-heated waste product is transferred through a combustion zone by a transfer mechanism which provides a grate at a floor of the combustion chamber;
- supplying air into the cavity of the combustion chamber through a plurality of air supplies;
- and
- incinerating the pre-heated waste product in the combustion chamber;
- wherein the pre-heating chamber heats the supplied waste product to remove moisture from the supplied waste product prior to transfer to the combustion chamber, with a temperature within at least an upstream region of the cavity of the pre-heating chamber being maintained at a temperature of less than 600° C., such that moisture is removed from the supplied waste product without causing release of chlorides from the supplied waste product.
