Abstract
A gasifier includes a combustion chamber and a pressure vessel surrounding the combustion chamber, wherein the pressure vessel includes an inner surface. A controller adjusts a pressure inside the pressure vessel so that a dew point temperature of corrosive compounds produced in the combustion chamber is less than a temperature of the inner surface of the pressure vessel. A method for operating a gasifier includes adjusting a pressure inside a pressure vessel surrounding the gasifier so that a dew point temperature of a corrosive compound is less than a temperature of an inner wall of the pressure vessel.
Claims20
A gasifier comprising:
- a. a combustion chamber;
- b. a pressure vessel surrounding the combustion chamber, wherein the pressure vessel includes an inner surface;
- and
- c. a controller, wherein the controller adjusts a pressure inside the pressure vessel so that a dew point temperature of corrosive compounds produced in the combustion chamber is less than a temperature of the inner surface of the pressure vessel.
A gasifier comprising:
- a. a combustion chamber;
- b. a pressure vessel surrounding the combustion chamber, wherein the pressure vessel includes an inner surface;
- and
- c. a controller, wherein the controller generates at least one of a fuel signal to control a flow of fuel to the combustion chamber, an oxidant signal to control a flow of oxidant to the combustion chamber, or a diluent signal to control a flow of diluent to the combustion chamber to adjust a pressure inside the pressure vessel.
A method for operating a gasifier comprising:
- adjusting a pressure inside a pressure vessel surrounding the gasifier so that a dew point temperature of a corrosive compound is less than a temperature of an inner wall of the pressure vessel.
