ABSTRACT:
Gas injection pipe for a sequential burner in gas variable-power boilers. An array of gas injectors which are located on the injection pipe may each be plugged by a corresponding valve which is mounted on the free end of a rigid blade transversely extending through an internal chamber of the injection pipe. A rotating shaft which is stepwise driven is provided at right angles to each blade with recesses which are angularly offset on the shaft. Each blade is provided with a stud which is located in a corresponding recess when the latter is in its upward position. The stud lifts up the blade when the shaft is rotated on purpose to open the valve.
