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.

2020/10/2 · Normal boiler pressure should be between about 1-2 bars [3]. The ideal boiler pressure is often marked as a range in green on the gauge itself. With red indicating the low and high boiler pressure zones. Bear in mind that your boiler may continue to work if the pressure is in these red zones.

However, it is now clear that the boiler and control and instrumentation issues cannot be resolved in time for the first unit of Medupi to deliver first power to the grid by 2013. "We are communicating this pro-actively, in line with our commitment to keep South Africa informed on the progress of the build projects," Eskom Chief Executive Officer Brian Dames said.

This enables the boiler to be operated independently of the turbines and correct steam temperatures and pressure to be obtained before the turbo-generator is started up. Should a turbine trip, the system allows the boiler to be operated at roughly 50% of its maximum, load, ready for a rapid restart, resulting in a saving of fuel oil.
