Nov 23, 2011 · By definition, a high pressure boiler is one that operates above 15 psi, while a low pressure boiler is one that operates at 15 psi or lower. Steam heating systems run with even lower pressure, typically at less than 1 psi in all. However, these types of boilers are less common (especially in newer homes), and operate using a different system.
Two types of gas burner are in use ‘Low pressure’ and ‘High pressure’. Low pressure burner. These operate at low pressure, usually between 2.5 and 10 mbar. The burner is a simple venturi device with gas introduced in the throat area, and combustion air being drawn in from around the outside. Output is limited to approximately 1 MW.
The size of the hole along with the manifold pressure determines the amount of gas that will flow into the burner. Click here for a chart of gas input for orifices at specific pressures. As an example, a #45 orifice with 3.5 in wc, will supply 17072 BTUs to the burner.
