Output, mean time and/or other weighted values for the DC current and voltage associated with the separator electrodes is compared and the relationship is used to regulate one or more combustion parameters. DETAILED DESCRIPTION - A method for regulating combustion parameters during the burning of ash-containing fossil fuels, generating a flue gas that is purified using at least one electrostatic separator unit with a constant or variable high voltage maintained across its emission and precipitation electrodes by a constant or variable DC current supply, comprises determining the output, mean time and/or other weighted values for the dc current and voltage. The resulting data is compared and the relationship is used to regulate one or more combustion parameters. ELECTRICAL POWER AND ENERGY - The combustion parameters are the amount of excess combustion air, the mixing of different air streams used to form the combustion air, oxygen concentration in the combustion air, moisture content in the combustion air, combustion temperature and particle size (distribution) of powdered coal being burnt. |
