Forced Circulation of Water in Boilers

Forced circulation of water in boilers is a process where water is pumped through the boiler tubes to increase the rate of heat transfer and maintain a constant temperature. This is achieved by using a pump to circulate the water through the boiler tubes, instead of relying on natural convection.

Types of Boilers

There are several types of boilers, each with their own unique characteristics. Some of the most common types of boilers include La-Mont boiler, Lancashire boiler, Velox boiler, and Benson boiler.

Forced Circulation in Boilers

Forced circulation of water does not take place in Lancashire boilers. Lancashire boilers are fire-tube boilers that rely on natural convection to circulate the water through the tubes. The hot gases from the furnace pass through the tubes, heating the water and creating steam. The steam then rises to the top of the boiler, where it is collected and used for various applications.

In contrast, La-Mont boilers, Velox boilers, and Benson boilers all use forced circulation to increase the rate of heat transfer and maintain a constant temperature. These boilers have pumps that circulate the water through the tubes, which allows for a more efficient transfer of heat.

Conclusion

Forced circulation of water is an important process in boilers that helps to increase the rate of heat transfer and maintain a constant temperature. While Lancashire boilers do not use forced circulation, other types of boilers, such as La-Mont boilers, Velox boilers, and Benson boilers, do rely on this process to operate efficiently.
