In the last session, we discussed Lamont Boiler, In today's session, we will discuss Benson Boiler along with its Definition, Parts, Working, Advantages, Disadvantages & Applications. So let's dive into the article!
Benson Boiler is a high pressure, drumless, supercritical water tube boiler that makes use of forced circulation but has a unique characteristic of the absence of the steam separating drum. Its main principle is that, at the critical pressure, the steam and water coexist at the same density, and heat is zero.
Benson Boiler was invented by Mark Benson in the year 1922.
The Benson boiler Diagram is shown below.
The parts of the Benson boiler are as follows.
The explanation for the Construction or parts of Benson Boiler are as follows:
The feed pump supplies the feed water from a hot well into the boiler.
The duty of the Economizer is to preheat the water from the combustion gases by the usage of the remaining heat.
The collected water is to be sent to the Radiant Parallel tube section such that it evaporates the water-steam mixture with the help of a radiator.
The steam-water mixture produced then moves to the transit section where this mixture is converted into steam.
The steam is passed through the Convection superheater where the steam is heated to high temperatures.
Finally, the steam without water droplets strikes the blades of the turbine to generate electricity.
These are the parts of Benson Boiler. Let's see the working principle of it.
The working of Benson boiler with respect to the above components are as follows:
Firstly, The feedwater passes through the economizer. The function of the Economizer is to increase the temperature of the feedwater (preheating) by absorbing the heat from the flue gases before they are sent to the atmosphere.
The feed water after circulation through the economizer flows through the Radiant parallel tube section to evaporate partly.
The steam-water mixture produced then moves to the transit section where this mixture is converted into steam.
The steam is now passed through the Convection superheater and finally supplied to the prime mover in order to drive the turbine.
As the superheater is an integral part of the process circulation system, no special starting arrangement for superheating is required.
Depending on the size and pressure required, the boiler can be put into service within 10 to 15 minutes.
The advantages of the Benson boiler are as follows.
The Disadvantages of the Benson boiler are as follows.
The applications of the Benson boiler are as follows.
