Solid Waste

Performance

Trecan’s controlled-air solid waste incineration systems, sold under the Trecaire brand name, are designed to produce excellent ash quality and the lowest practical emissions and auxiliary fuel useage.

The Combustion Proces

Trecaire incinerators use a two stage combustion process. Solid waste is charged into the incinerator’s primary chamber and ignited by the primary burner(s). Following ignition, air is supplied sub stoichiometricly via evenly distributed primary air ports in the incinerator’s refractory hearth. The solid waste is decomposed in this semi-pyrolitic (starved air) environment resulting in a typical primary chamber exit temperature of 760°C (1400°F).

The smoke and gases produced in the primary chamber are routed to the secondary chamber where they are completely oxidized under turbulent excess air conditions. The secondary burner maintains chamber outlet temperature at a minimum of 1000°C (1832°F). Secondary chambers are sized to provide the required residence time (typically 1 to 2 seconds) at operating temperature.

Two Basic types

Trecaire incinerators are available in two basic types:

• Ram Feed
• Batch Operation

Batch Feed Model

We have six standard batch type units with primary chamber volumes ranging from 50 to 500 ft3 (1.4 to 14.0 m3).
