摘要： A burner control system for an intermittent pilot burner system uses a single pole double throw relay to control first and second electromagnetic valves [25,29] respectively supplying fuel for both burners [42,45] and for the main burner [45] only. The normally open contact pair [17,18] supplies the current for the first [29] and the normally closed contact pair [16,17] supplies the current for the second valve [25]. By selecting the valve supplying fuel for both burners to be of the type which has an appreciably higher pull-in current than drop-out current, and by shunting the relay's normally open contacts with a properly selected resistor [20], only a single relay is necessary. This resistor [20] is selected to supply current sufficient to hold the valve [29] open (current greater than the drop-out value) after the valve has received pull-in current through the closing of these normally open contacts [17,18], but insufficient to open the valve. Use of a single relay reduces cost, size, and power, and increases safety of the control system.

摘要： A fuel burner includes an electrical igniter [15] which lights a pilot burner [23] which then lights the main burner [24]. Operation of each of these steps is monitored, and if any are improper, the control device reverts to lighting the pilot burner with the main burner valve [27] shut. If the igniter [15] is sensed as incapable of lighting the pilot burner [23], the pilot burner valve [31] is shut, and an error is indicated to the operator.
