Jan 30, 2006 · Since combustion equation has 3 moles of gas on both LHS & RHS, for exhaust gas can use (NG + combustion air) volume. Only need to correct for temperature per gas law. Best to use the actual exhaust T, but if not available, use 400 o F. The boiler mfr. recommends the stack ID, so from volumetric flow, you get the exhaust velocity.

NATURAL GAS PIPING Table 1 shows capacity of a natural gas line for a given initial pressure with a 5% pressure drop. For example, consider a 500 hp boiler, which requires 20,925 cu.-ft. / hr. A 5 psi initial pressure is available for 100 ft. of pipe. To find the correct pipe size, go to the line for initial gas pressure reading 5 pounds. Now
