What is the efficiency of water tube boiler?

The initial value of boiler efficiency for Z Boiler is depending on the boiler type, but it is normally 80-88%. In short, 80-88% in the generated heating value after the fuel is burnt by the burner regenerates into the steam heating value, the remain of 12-20% is loss.

What is the construction of water tube boilers?

The water tubes are inclined at an angle of 15°. This boiler is made of steel shell whose both ends are welded. A water level indicator, pressure gauge, safety valve, and manhole are the mountings used. The water tubes are placed below the shell by support from the bottom at an angle of 15°.

What is typical boiler efficiency?

Although older furnace and boiler systems had efficiencies in the range of 56% to 70%, modern conventional heating systems can achieve efficiencies as high as 98.5%, converting nearly all the fuel to useful heat for your home.

What is the efficiency of a water tube boiler?

Water Tube Boiler is a high-pressure boiler that operates at a pressure of about 165 bar. Basically, in this boiler, water will be flown inside the tubes surrounded by flue gases. More steam is generated by using this boiler so, the overall efficiency of the boiler is high. The water Tube boiler is shown in the figure below.

Why are water tube boilers used in power plants?

“The ability of watertube boilers to be designed without the use of excessively large and thick walled pressure vessels makes these boilers particularly attractive in applications that require dry, high-pressure, high-energy steam, including steam turbine power generation”.

What are the different types of water tube boilers?

There are different types of Water Tube Boilers. They are The entire arrangement is enclosed in brickwork. A Stirling boiler has several drums and also a mud drum. Depending upon the requirement the number of drums is chosen. A Stirling boiler can work up to a pressure of 60 bar and the production of steam would be around 50000 kg/hr.

What is the efficiency of a Stirling boiler?

A Stirling boiler has several drums and also a mud drum. Depending upon the requirement the number of drums is chosen. A Stirling boiler can work up to a pressure of 60 bar and the production of steam would be around 50000 kg/hr. The efficiency of this boiler will be around 60 – 80 %.
