The Normal PSI Reading for a Hot Water Boiler

The standard cold water operating pressure of most U.S. and Canadian hot water boilers is 12 pounds per square inch (psi). If the boiler pressure drops below 12 psi, the valve will allow new water into the unit to bring up the pressure reading.

Boiler Efficiency and Combustion | Spirax Sarco

Pressure jet burners. A pressure jet burner is simply an orifice at the end of a pressurised tube. Typically the fuel oil pressure is in the range 7 to 15 bar. In the operating range, the substantial pressure drop created over the orifice when the fuel is discharged into the furnace results in atomisation of the fuel.

2020-9-6 · Fuel It is the purpose of the burner to present the fuel in suitable condition for proper combustion. Generally this means atomising the fuel and giving it some axial (for penetration) and angular (for mixing) velocity. For effective atomisation the viscosity of the fuel is critical, for fuels heavier than gas or diesel oils some degree of heating is required.
