Turndown ratio - Wikipedia

Boilers using the pressure jet type of burner, i.e. with a fan, (usually with 35 second oil) can achieve a turndown ratio of 2, while the rotary cup type burner can achieve 4. Condensing oil boilers are fairly unusual; the condensate from the combustion of oil is far more aggressive than gas, mainly due to sulphur content.

The fluidised bed in the CFB absorber requires the observance of certain parameters. In order to guarantee stable plant operation even during part load operation of the boilers, the clean gas is therefore recirculated in a controlled manner downstream of the FGD fan into the raw gas channel upstream of the CFB absorber.
