Operating method for multi-boiler heating plant incorporates compensation for temperature disparity between mean boiler temperature and actual circulation temperature

摘要

The operating method uses initial cascade regulation with provision of a required circulation temperature for all boilers, subsequent individual regulation of the boilers using the given circulation temperature and final combining of the boiler flows for providing a common actual circulation temperature. The actual temperatures of the boilers in operation are used for calculating a mean boiler temperature, used with the actual circulation temperature for providing a difference temperature used for the cascade regulation.
