Fan Laws and Fan Performance Fluid Flow Engineering

Aug 09, 2019 · Fan Laws In general, the fan laws are typically used to calculate changes in flow rate, pressure and power of a fan when the size, speed or gas density is changed. In the fan laws outlined in Table 1 below, the subscript 1 represents the initial existing condition and subscript 2 represents the desired calculated condition.

Boiler Fan Fault Problems And Cures

One sensor that is directly related to the fan's operation, is the air pressure switch. When the fan fires into life, the air pressure switch should notice a difference in air pressure. Once the boiler's PCB sees this signal, it's going to demand gas from the gas valve, and use the spark generator to produce a flame.
