How Does the Natural Gas Delivery System Work? |

Gas flowing from higher to lower pressure is the fundamental principle of the natural gas delivery system. The amount of pressure in a pipeline is measured in pounds per square inch. From the well, the natural gas goes into "gathering" lines, which are like branches on a tree, getting larger as they get closer to the central collection point.

boiler dynamic gas pressure requirement - hvac

2017-4-6·I am designing a hot water loop for an industrial process and have a question about gas pressure requirements. Most boilers give a minimum gas pressure requirement of ~4-5"w.c. but this value is static pressure. What I want to know is the dynamic pressure requirement. IE, what the boiler inlet pressure needs to be when gas is flowing. Our static pressure is 7"w.c. and I know that for out btu
