Pennram - 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. The primary chamber is of an air tight design, eliminating in leakage of unwanted air.
- In the horizontal models, Pennram uses the multiple hearth design. For example:
- 300-750 lb./hr (135-340 kg/hr) units
- 2 level hearth, 1 ram.
- 800-2,800 lb./hr (360-1270 kg/hr) units
- 3 level hearth, 2 rams.
- 3,000-5,500 lb./hr (1360-2500 kg/hr) units
- 3 level hearth, 2 rams.
Pennram uses a much heavier liner in the chamber than others and in many cases, a heavier shell. Pennram uses a full 9″ firebrick liner consisting of 4-1/2″ firebrick and 4-1/2″ insulating firebrick; the poured sections of the chamber consist of 6″ castible refractory and 3″ of block insulation behind the refractory. The heavier firebrick costs more, but lasts longer and is more resistant to the chemical attack of the internal atmosphere, thus ensuring long-term efficiency and economy.
In the design of Pennram incinerators, air delivery to the primary chamber is cut off during a charge to avoid the initial flash of volatile waste into hydrocarbon. This “flash” is uncontrollable in the presence of excess oxygen at high temperature and often results in visible emissions. The air is controlled to prevent these upset conditions.
