A syngas cooler is configured to cool a syngas. The syngas cooler includes a superheater heat exchanger, which further includes a first header configured to receive saturated steam, a second header configured to discharge superheated steam, and a first group of tubes directly coupled to and vertically extending between the first and second headers. Each tube of the first group of tubes includes an outer surface that interfaces with the syngas and a respective length between the first and second headers, and each tube of the first group of tubes does not contact another tube along the respective length to enable a flow of the syngas around each tube's outer surface along its respective length and between each tube.
