Burner regulator for heating system burners - uses electronic switching appts. to vary periods between burner switching by thermostat

摘要

The burner regulator has switch for switching burner on when lower water temperature is reached. When upper temperature is reached switching operations of the regulator period between switching operations of the regulator is varied in relation to the given performance demands. It also ensures that the period is longer in lower performance ranges than in the upper performance range. The period between the burner switching on and off are adjusted directly for a given boiler type and size in order to ensure correct combustion characteristics. The period between the switching on and off can be varied by a number of methods. For example in an electronic regulator resistor responding to external temperature can be installed in the circuit for modifying switching period.
