Natural Gas - The National Board of Boiler and Pressure

Pressure gauges should be installed before and after the gas pressure regulator and at the burner, in order to monitor pressure to ensure they are within the manufacturer's recommendations. Editor's note : Some ASME Boiler and Pressure Vessel Code requirements may have changed because of advances in material technology and/or actual experience.

Gas Furnaces:Manifold Pressure Adjustment | hvac machinery

Manifold pressure should be set at 3.5 in W.C. for natural gas. Control manufacturers normally preset the pressure regulator in natural-gas valves at the time of manufacture so that natural-gas units are fired at this 3.5 in W.C. rate. Only small variations in the gas flow should be made by adjusting the pressure …

Natural Gas Fired Boilers

The boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal and about a 11% heat loss while firing natural gas. When firing natural gas, other losses such as dry gas loss, moisture in fuel and
