This training presentation has been prepared to provide the trainees with a detailed guidance to operating AQ type Aalborg boilers in emergencies. It is intended to demonstrate the users the correct sequence of actions to be followed.
In short, following should be carried out: first, the Boiler Mode key shall be changed over from Auto to Manual, and then the Burner changed to manual - this is done by pressing the Burner Auto button (note that the green light shall go off); after that, the selector switch of the Combustion Air Fan shall be changed from Auto to 0 position; make sure that the vanes are completely shut and only after that you may change to Manual position (at this time the fan will start running); then, you shall press the Combustion Controller Off button in order to put off subject controller.
It shall be noted that two potentiometers have been installed on the Panel with the purpose of controlling both Air and Oil flows when the Boiler is being fired in Emergency mode.... A very useful training source for the crew members engaged in operation and maintenance of the subject boilers.
