Boiler Combustion Air Flow Measurement | Yokogawa America

On many boilers, air flow is the measured differential between the furnace inlet and the boiler outlet. This takes the differential of the hot gases as they flow through the furnace, across the convection section, and out the stack. In most cases, the differential ranges from 0.5 to 2.0 inches of water. Errors From Drift and Zero Shift Most

Flow rate in central heating system | DIYnot Forums

Dec 28, 2009 · A 41kW boiler with a 20C differential required a flow rate of 41/ (4.2x20) =0.49 litres per second or 1.76 m³ per hour. If you are getting a temperature drop of 30C then the flow rate is 41/ (4.2x30) = 0.33 litres/ sec or 1.17m³ per hour. This graph shows how the flow rate (X axis) of the 25-55 varies with pressure (Y axis).
