How is burner pressure related to boiler pressure?

Question

please explain in detail that how will boiler pressure affect the burner pressure operations,i.e will the burner pressure increase?

if you have a chart showing their relationship,please tell me.

Answer 1

no direct relationship at all.

Yes, if you increase the burner pressure, the flame will get hotter and that will heat the water up more and increase the pressure. But this is a very indirect relationship. And it depends very much on the installation.

And it does not work in reverse. Increase the boiler pressure and you do not change the burner pressure. How could you, the burner pressure is controlled by an external valve or some other control.

Answer 2

As a general rule, burner pressure remains fairly constant.  If the load on the boiler increases and you need to make more steam to keep up, then the size of the burner diffuser is usually changed to a larger o*****e to allow more oil to pass through.  More oil means more heat which means more steam.  Although boiler pressure is also relatively constant, it too can change depending on conditions.
