Abstract
A pressurized incineration facility (100, 200) includes: a pressurized incinerator (1) which incinerates a processing object (P) under a pressure increased by compressed air (A); a turbocharger (5) which produces the compressed air by being rotationally driven by combustion exhaust gas (G) of the pressurized incinerator; and a seal device (5i) which jets seal gas (S) to a rear surface (5a1) of a turbine impeller (5a) of the turbocharger.
Claims11
A pressurized incineration facility comprising:
- a pressurized incinerator which incinerates a processing object under a pressure increased by compressed air;
- a turbocharger which produces the compressed air by being rotationally driven by combustion exhaust gas from the pressurized incinerator;
- and
- a seal device which jets seal gas to a rear surface of a turbine impeller of the turbocharger,
- wherein the turbocharger comprises:
- a turbine housing accommodating the turbine impeller;
- a bearing housing rotatably supporting a rotary shaft fixed to the turbine impeller;
- and
- a circular heat shield plate disposed between the turbine housing and the bearing housing and provided with an opening into which the rotary shaft is inserted, and
- wherein a jetting port of the seal device configured to jet the seal gas to the rear surface of the turbine impeller is formed between the bearing housing and an edge of the opening of the heat shield plate.
A pressurized incineration method comprising steps of:
- incinerating a processing object under a pressure increased by supplying a pressurized incinerator with compressed air produced by a turbocharger;
- producing the compressed air by rotationally driving the turbocharger by combustion exhaust gas of the pressurized incinerator;
- and
- jetting seal gas to a rear surface of a turbine impeller of the turbocharger,
- wherein the turbocharger comprises:
- a turbine housing accommodating the turbine impeller;
- a bearing housing rotatably supporting a rotary shaft fixed to the turbine impeller;
- and
- a circular heat shield plate disposed between the turbine housing and the bearing housing and provided with an opening into which the rotary shaft is inserted, and
- wherein the seal gas is jetted to the rear surface of the turbine impeller from a jetting port of the seal device formed between the bearing housing and an edge of the opening of the heat shield plate.
