Abstract
A system includes a syngas cooler configured to cool a syngas. The syngas cooler includes a first syngas cooler section configured to cool the syngas and a second syngas cooler section configured to cool the syngas and generate a first superheated steam with an enthalpy of less than approximately 3800 kJ/kg.
Claims17
A system, comprising:
- a syngas generator configured to generate a syngas;
- a syngas cooler configured to cool the syngas, wherein the syngas cooler comprises:
- a first syngas cooler section including a first input and a first output, and configured to cool the syngas along a syngas path in a first shell of the first syngas cooler section and generate a saturated steam, wherein the first output outputs the saturated steam;
- and
- a second syngas cooler section including a second input and a second output, and configured to cool the syngas along the syngas path in a second shell of the second syngas cooler section and superheat the saturated steam to generate a first superheated steam with an enthalpy of less than approximately 3800 kJ/kg, wherein the second syngas cooler section is disposed along the syngas path downstream of the first syngas cooler section, and the first output is coupled to the second input;
- and
- a steam user connected to the second output.

A system, comprising:
- a gas fuel generator configured to generate a gas fuel;
- a steam generator configured to generate a steam;
- a gas fuel cooler configured to cool a gas fuel for power generation, wherein the gas fuel cooler comprises:
- a first gas fuel cooler section including a first shell and a first tube, and configured to cool the gas fuel along a gas path in a first shell of the first gas fuel cooler section and generate a first superheated steam in the first tube of the first gas fuel cooler section, and the steam generator is coupled to the first tube;
- a second gas fuel cooler section including a second shell and a second tube, and configured to cool the gas fuel along the gas path in the second shell of the second gas fuel cooler section and generate a second superheated steam in the second tube of the second gas fuel cooler section, wherein the second gas fuel cooler section is disposed along the gas path downstream of the first gas fuel cooler section, and the first tube is coupled to the second tube
- a first steam connector configured to output the first superheated steam through the first tube;
- and
- a second steam connector configured to output the second superheated steam through the second tube.

A system, comprising:
- a gas cooler configured to cool a gas, wherein the gas cooler comprises:
- an elongated enclosure having a longitudinal gas flow path;
- a first gas cooler section disposed in the elongated enclosure, wherein the first gas cooler section is configured to cool the gas along the longitudinal gas flow path;
- a second gas cooler section disposed in the elongated enclosure, wherein the second gas cooler section is configured to cool the gas along the longitudinal gas flow path and generate a first superheated steam;
- a steam drum configured to provide a saturated steam from the first gas cooler section to the second gas cooler section;
- a third gas cooler section disposed in the elongated enclosure along the longitudinal gas flow path, wherein the third gas cooler section is configured to cool the gas along the longitudinal gas flow path and generate a second superheated steam;
- and
- an after cooler section disposed in the elongated enclosure, wherein the first gas cooler section, the second gas cooler section, and the after cooler section are disposed in series one after another along the longitudinal gas flow path, wherein the second gas cooler section is disposed axially between the first gas cooler section and the after cooler section along the longitudinal gas flow path.
