Natural Circulation Boiler and Forced Circulation Boiler

2016-12-16 09:35:37

In ZBG product lists, most products are natural circulation boilers, and only a few of them is forced circulation boilers like QXX series high speed external circulating fluidized bed boiler.
In QXX series high speed external cfb boiler, the primary and secondary air blowers provide air to boiler chamber. Forced circulation refers to the necessity of constant mechanical pumping of steam and water to ensure steady flow rate.

Natural Circulation Boiler and Forced Circulation Boiler

Most boilers in our factory are natural circulation boiler, such as chain grate boiler, oil gas fired packaged boiler,e tc. Natural circulation refers to the natural circulation of steam and water. This type of circulation is driven by force incurred by the density differentiation of steam and water. It only requires a feed-water pump to initiate the flow without relying on any other type of mechanical pump to stabilize circulation. Hence, natural circulation design can lower operational cost in electricity. It can also eliminate the risk of potential vapor lock during a potential occurrence of power failure.

For further information about our industrial boilers natural circulation or forced circulation, please contact with our consumer service.
