Solved DAONLIUEA) 1. The pressure of steam inside a boiler

The pressure of steam inside a boiler is recorded by a pressure gauge which shows 1.2 N/mm². If the barometer reads the atmospheric pressure as 770 mm of mercury, find the absolute pressure of steam inside the boiler in N/m², kPa and bar. 2. In a condenser, the vacuum is found to be 145 mm of mercury and the barometer reads 735 mm of mercury.

What Should The Boiler Pressure Be When The Heating Is On?

When the heating is turned on your boiler pressure should be between 1.5 and 2 bar. Most boilers will highlight this area on the pressure gauge in green to help you see if the needle is pointing to the correct amount of pressure. Some boilers will also have the critical zones below 1 and above 2 marked in red to help you identify any issues.
