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.

Superheat Steam Temperature Control

High turbine efficiency over a wide load range depends a great deal on having a constant steam temperature over that load range. Therefore, it is necessary to design a boiler that can provide this constant steam temperature over the load range, which can be 50 percent of full load or more.

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.

Superheater and Reheater Temperature Control in Boilers

1) "Net stack temperature" is temperature difference between flue gas temperature inside the chimney and room temperature outside the burner. Flue Gas Loss with Oil Combustion. The relation between temperature difference in flue gas and supply air, the CO 2 concentration in the flue gas, and the efficiency loss in the flue gas oil combustion, is expressed below:

Why do we use superheated steam for a steam turbine rather

Because superheated steam has more energy in it than saturated steam. A turbine can convert more heat energy from superheated steam and turn it into mechanical energy. Superheated steam is under higher pressure and can be directed through more phases inside of the turbine.
