Hello,
I am carrying out some experiments on a small scale fired gas burner with a gas gas heat exchanger at the top. I alter the biogas rate and in some other experiments I alter the air flow rate in the heat exchanger.
I have realised that efficiency varies widely from 35-70% depending on the air flow and biogas flow.
For example as air flow increases (keeping fuel constant), efficiency increases.
What sort of efficiency does a manufacturer indicates in the specifications? Max, Min or Average?
Regards
Andreas
