Abstract
A method of thermal decontamination of organic wastes in which the waste is treated in a primary incinerator by a heat source such that solid residue is collected from the incinerator and exhaust fumes then participate in an industrial thermal process by being directed to an industrial containment by combusting the exhaust gases together with fuel and an oxidizer with oxygen concentration in excess of air to decontaminate the exhaust gases and using the heat produced in the industrial process.
Claims20
A method of thermal decontamination of organic wastes comprising the steps of:
- a) directing waste material into a primary incinerating chamber;
- b) providing in said primary incinerating chamber a controllable amount of heat communicating with said waste material and a flow of a primary oxidizer communicating with said waste material;
- c) thermally decontaminating said waste material in said primary incinerating chamber to produce decontaminated solid residue and exhaust fumes;
- d) directing said exhaust fumes to an industrial thermal process containment means having a combustor means to produce industrial product;
- e) supplying controllable amount of fuel to said combustor means;
- f) supplying to said industrial containment means a secondary oxidizer at least part of which has oxygen content above 21%;
- g) directing at least part of said fuel, at least part of said secondary oxidizer, and at least part of said exhaust fumes to mix in a flame to thermally decontaminate said exhaust fumes generating secondary combustion gases;
- h) providing a heat flux from said secondary combustion gases to the industrial product.
