Pressurized Combustion in Velox Boiler

Velox boiler is a forced circulation water tube boiler in which the combustion takes place under pressure. This type of boiler makes use of pressurized combustion to achieve high thermal efficiency. Let's understand the working of Velox boiler in detail.

Working Principle of Velox Boiler

The working principle of Velox boiler is based on the forced circulation of water through the tubes. The combustion takes place in a combustion chamber which is located at the bottom of the boiler. The fuel is burnt under pressure and the hot gases are directed to the combustion chamber. The combustion gases pass through a series of air ducts and then enter the combustion chamber.

After entering the combustion chamber, the hot gases mix with the compressed air. The compressed air is supplied by a compressor which is driven by a turbine. The compressed air mixes with the hot gases and the mixture is directed to the heating surface of the boiler.

The heating surface of the boiler consists of a set of tubes through which water circulates. The hot gases transfer their heat to the water and the water gets converted into steam. The steam is then directed to the superheater where it gets superheated. The superheated steam is then sent to the turbine for generating power.

Advantages of Velox Boiler

- High thermal efficiency
- Compact design
- Easy to operate
- Low maintenance cost

Conclusion

Velox boiler is a type of water tube boiler which makes use of pressurized combustion to achieve high thermal efficiency. The boiler operates on the principle of forced circulation and is suitable for power generation applications. The boiler is easy to operate and has a low maintenance cost.
