Air leakage into the primary chamber, which is operated under a slight negative pressure, is the number one problem with many incinerators, as excess air in the primary chamber makes it difficult to control the temperature. Charge ram retracts to a position clear of the firedoor and stops. Firedoor fully closes. Charge ram fully retracts. Hopper lid opens.
All components prove position before continuing the sequence.
An adjustable water spray is initiated when the firedoor closes. If the system has ash rams, the rams cycle prior to the charge sequence. If there is more than one ash ram, the lowest ram cycles first. Back to Top Primary Chamber Pennram s primary chamber is superior to that of other makes mainly in the hearth design and the way the combustion air is introduced. In the vertical model, air is introduced into the center of the chamber as well as the sides of the chamber.
