Flue gasses enter the main flue tube and it leads to the boiler chimney.A spring-loaded safety valve is mounted on the boiler. By this way water around the flue tube become heated and generate steam.
Application of Cornish Boiler: This boiler is used in many industries like textile, sugar, paper and some other small industries. But in Lancashire, there are 2 flue tubes. After that flue gases pass out through the chimney. You will find only one internal flue tube in this boiler.
Two flue tubes are located of two sides of the boiler shell and the third one is on the bottom section of this boiler. This furnace is located at the front side of the tube and it also called the furnace tube. First, the water starts to come in the water tubes from the drum through down take header.
The working pressure and quality of steam required: The boiler should generate maximum amount of steam at a required pressure and temperature and quality with minimum fuel consumption and expenses Steam generation rate should be as per requirements of intended use, an extra over designed or under designed boiler is not a good choice. Now let’s discuss the working of Babcock and Wilcox boiler step by step.
A damper is used to regulate the flow of air and it also controls the steam generation.Coal start to burn inside the furnace and generated flue gas. The main function of this stop valve is to regulate the generated steam between the steam pipe and boiler. This valve is normally located at the top section of the boiler shell.Then there is a stop valve and it’s located at the top of the boiler shell. The working principle of water tube boiler is very interesting and simple. This brick arc is used for preventing entering the ashes and burning coal into the boiler internal parts like flue tube.
The working principle if this Cornish boiler is very simple.This boiler is used in many industries like textile, sugar, paper and some other small industries.

Actually in fire tube boiler one closed vessel or shell contains water, through which hot tubes are passed. According to IBR, the definition of the boiler is as per below, The boiler is a closed vessel having the capacity of 22.75 litters or more which is used for generating steam. Construction and maintenance cost of this boiler is very low and it has the ability to overcome load fluctuation during operation. These hot gas tubes are immersed into water, in a closed vessel.
But it has a low steam production rate = 6500 kg/hr and maximum steam pressure range is 10.5 bar.
This boiler has a long horizontal cylinder with a single large flue containing the fire. It is compactness and portable boiler. Let us draw a very basic diagram of water tube boiler. The water present in the inclined water tubes gets heated up by the hot flue gases.
As we know this boiler has only one internal flue tube.
Cornish boiler design has similarity with the This boiler made with a long cylindrical external shell.
A high steam low water safety valve is located near with stop valve.
The main function of this safety valve releases the excess steam pressure when steam pressure is very high in the boiler. Cornish Boiler is a fire tube boiler. These fire tubes or hot gas tubes heated up the water and convert the water into steam and the steam remains in same vessel.
The flue gas passes through the boiler internal flue tube.
But generally, the brick arc deflects the flue gases upwards.

The main function of this valve is to release the generated steam when the water level falls below a certain level.Next, there is a feed pipe which is controlled by a feed valve. basically a closed vessel into which water is heated until the water is converted into steam at required pressure When pressure decrease and reach rated pressure inside the boiler then this pressure valve goes off. It also used to produce steam to run a steam turbine and it can found in marine industries.By this article, you already know that this boiler has a simple design and easy construction. It’s called the main flue tube. Its use for feeding water inside the There is the main hole that also uses to inspect inside the boiler. Post was not sent - check your email addresses! This boiler needs more ground because of its horizontal structure.Click to email this to a friend (Opens in new window)
There is another flue tube is present.
Then you will find fire grate or so-called furnace. It was first adapted by Richard Trevithick’s and, first installed at Dolcoath mine in the year of 1812.
