Guess – Could Piston Initiated Pulsating Pressure Increase Effectiveness In Coal Fired Stations?

I was thinking. You don’t immediately put out a candle light when covering it.

From this I speculate that you can initiate a pulsating pressure with a piston in the coal burner. Inspired by a piston engine. I guess that this would increase the pressure. But only temporary. An air inlet would then also increase the oxygen uptake.
