SAFETY SYSTEMS GUARDING AGAINST BURN-BACK

1. Pulse-controlled burn-back protection. The system sprays water onto the fuel in the feed auger if

the temperature rises above a set value. It operates on the pulse-pause principle until the tempera-

ture has fallen. It neither stops the production of heat nor emits an alarm.

2. Burn-back thermostat. The automation system is equipped with a sensor. When it trips, the

protection system emits an alarm and turns off the equipment. The burner augers are run for 60

seconds so that the overheated fuel can be sent to the boiler.
