Boiler Introduction

Superheat refers to the process of increasing the temperature of steam above about 400°F and 100 psi to produce a very "dry" steam with absolutely no water vapor. This feature is most common in very large power plant boilers of watertube construction. An additional heat exchanger capable of the high temperatures and pressures is required.

ORGANIZING COMMITTEE

As a result, high temperature flue gases are produced. The saturated steam produced in the Complementary Steam Generation and Syngas cooling sections utilizes the heat from the hot furnace gases and produce high pressure superheated steam. This steam is introduced in the gasifier for the main process.

Wet Steam vs. Dry Steam: The Importance of the Steam Dryness

When steam is more than 100% dry it is called superheated steam. This type of steam is created by adding heat above the saturated steam threshold. The added heat raises the steam’s temperature higher than its saturation point, allowing the amount of superheat to be easily determined by simply measuring its temperature.
