If you use saturated steam, the main source of the heat is provided by the condensation of the steam at a constant temperature. The energy provided by the condensing steam is significantly more than what you can get from just changing the temperature of superheated steam. When the temperature remains constant, design calculations are also a lot easier; the temperatures stay the same (or almost the same) for the steam along the entire run and the pressure stays the same (or almost the same).

How steam required for steam tracing of jacketed lines is calculated how much steam required for sulfur melting?
The steam required for steam tracing is calculated on the basis of the amount of heat transfer that is required or the temperature that you want to maintain with the help of steam. It also depends on the pipe material through which the steam is passing,the condition of the steam that whether it is saturated or superheated etc. Overall heat transfer cofficient is calculated considering all the factors like fouling or scaling,inside and outside dia. , surface area etc. After calculating the amount of heat to be transferred, the requirement of rate of steam is calculated. Generally, Low pressure steam is used as it has got more latent/Sensible heat as compared to MP or Superheated steam.
How is a boiling water reactor's superheater 'heated'?
They don't. BWR's run wet saturated steam. There is no superheating in a BWR, because there is no way steam would come in contact with a heat source. The plant must be built to be compatible with wet steam that could condense.
Why you use boiler in oil refinery?
Use of water in a refinery is makeup for boiler feed. The chief uses of steam are for stripping, steam distillation, and vacuum distillation. The steam comes in contact with the products in these operations, and generally the steam condensate is so highly contaminated that it cannot be reused for boiler feed or for other purposes. Steam is also used for process heating, for pumping, and, in some refineries, for generating electric power
Where would a steam separator be located on a boiler?
In the steam drum, where steam exits and flows to the superheaters.
Advantages of steam power plant over diesel power plant?
1. Can be made in much greater output plants 2. Steam plants can use a variety of fuel sources including nuclear fuel, whilst diesel fuel is more expensive and best reserved for transport use.
How many kinds of steam?
There are three kinds of steam 1) saturated steam, 2)super saturated steam 3) wet steam.
What is the device use to sterilize equipment and supplies by subjecting them to high pressure saturated steam?
An Autoclave is a device used to sterilize equipment and supplies by subjecting them to high pressure saturated steam.
What is the trace heating or heat tracing?
Heat tracing can be of 2 types: 1] Electrical Heat tracing: 2] Steam Tracing: Electrical heat tracing can be described as an insulated electrical heating cable, which is spiralled around the process fluid pipe( or object that needs to be heated), after which the pipe and tracing is insulated with the appropriate type and thickness of insulation lagging material. In steam tracing, instead of electrical heating cable, small pile is spiralled which carry steam thereby heating the desired object.

Is steamed rice saturated?
Steamed rice is saturated with water from the steam.
Where demineralise water is used?
For the production of saturated steam in chemical plants,we have to use pure,filtered,and demineralised water.
Can saturation or dry steam be seen with the naked eye?
can saturated or dry steam be seen
Why not you use steam tracing in sulfur lines instead of steam jacket?
sulfur melting point is minimum 116 degree centigrade, so if you are using LP tracing it is not maintain that uniform temperature and line get solidify, otherwise if you are using MP tracing the temperature is more ,ie > 150 degree centigrade. so > 150 degree centigrade the sulfur viscosity will increase. so LP jacketting is best for sulfur line
What is the difference between tracing paper and wax paper?
tracing paper is extremely thin translucent ordinary paper, you can write on it. wax paper is paper saturated with wax, you can't write on it.
What is steembath?
A "steam bath" is a room with super saturated steam at about 50 or 60 degrees Celsius.
Why saturated steam is used in exchangers frequently rather then superheated?
The heat transfer coefficient of superheated steam is poor. Saturated steam has a better heat transfer coefficient, and also most of the heat transferred from steam occurs because of the condensation phase change.
What is the temp of 50psig steam?
Saturated = 366 Deg F
