Saturated vs Superheat Steam Conditions - Nationwide Boiler Inc

This is called superheated steam. Superheated steam has a lower density, so lowering the temperature does not revert it back to its original liquid state. Dropping the temperature of saturated steam, however, will revert it back to its old form of water droplets. Superheated steam has more energy and can work harder than saturated steam, but ...

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.


A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil.The heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation, cooking, and sanitation

Steam Calculators: Boiler Calculator

Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

Industrial Refrigeration Handbook

A general observation of the compression lines (lines of constant entropy) is that they become flatter as they move to regions of greater superheat. The consequence of this change of slope is that the increase in enthalpy during the compression, which indicates the power required in the compression, is greater with high inlet temperatures.

The Temperature in Your Boiler and the Dangers of Overheating

The Temperature in Your Boiler and the Dangers of Overheating Something that often surprises homeowners about their boilers is that they don’t actually “boil.” The energy applied to the water in the tank raises it to high levels, but not to the point that it converts the water into steam.


This article is about the phenomenon where a liquid can exist in a metastable state above its boiling point. See superheated water for pressurized water above 100 °C. See superheater for the device used in steam engines.. In physics, superheating (sometimes referred to as boiling retardation, or boiling delay) is the phenomenon in which a liquid is heated to a temperature higher than its ...

Pros and Cons of Using a Natural Gas Boiler

A natural gas boiler meets the hot water needs for many homeowners. The boiler is fueled by natural gas, one of the cheapest fuels available for home heating. Other energy sources used to fuel residential boilers include propane, oil and electricity.

the consequence of high superheat temperture in steam boiler

General Boiler Information. Superheat is a term that refers to higher temperature steam, as a result of a second special steam heat exchanger in the boiler that allows steam pressure to increase, thereby taking on more BTUs (in excess of 500 psi is typical of superheat). Superheated steam is very dry steam. Learn More

Energy Conversion: Chapter 8: Refrigeration and Air

A pump is a device that moves a liquid from a region of low pressure to one of high pressure. In the Rankine cycle the condenser condensate is raised to the pressure of the steam generator by boiler feed pumps, BFP. The high-pressure liquid water entering the steam generator is called feedwater.

Superheater and Reheater Temperature Control in Boilers

All boilers used for both process and power generation plants have to maintain steam parameters within a particular range. The pressure and temperature of steam at superheater and reheater outlets are to be maintained to achieve an optimum plant efficiency. In large capacity boilers, injection type desuperheating is more popular.

Natural Gas Boilers

A gas-fired boiler provides hot water to taps throughout the home and also to radiators in the central heating system. Gas is an extremely efficient fuel and modern condensing boilers have large heat exchangers that collect and use almost all the heat created when the gas burns for heating and hot water, making the boilers 90% or more efficient.
