Although it's a method typically used in large power plants, individual inventors like the author were conducting successful experiments with efficient small scale fluidized bed combustion in the 1970s.
Rocky Golden attaches the blower and warm-up burner to his prototype fluidized bed for a demonstration.
This fluidized bed combustion unit is a scaled down—and easily understandable—version of a multimillion-dollar technology.

In less than five minutes the combustion chamber was glowing hot—looking much like the bubbling caldron of a volcanic crater—and prepared to burn almost anything
The author adds limestone to a the bed to prevent the low-carbon, high sulfur coal he chose as fuel from producing a pollutant.
