What is the interlocking between the industrial boiler's forced draft fan and induced draft fan?
The forced draft fan and induced draft fan are two critical components of an industrial boiler that work together to maintain proper airflow and control the combustion process. The interlocking system between these fans is designed to ensure safe and efficient operation.
The interlocking system includes sensors and controls that monitor the airflow and pressure in the boiler. If there is a malfunction or issue with either the forced draft fan or the induced draft fan, the interlocking system will automatically shut down the other fan to prevent any damage or safety hazards.
