The automatic control equipment (1) is for a burner (2) with a combustion chamber (4). Fuel is supplied to the combustion chamber by a motor operated regulating valve (5). Combustion air is supplied by a fan (7). The fan is driven by a variable speed motor (6). A sensor (8) detects the instantaneous speed of the fan and provides a signal which initiates any correction of the position of the regulating valve required. |
