Combustion. A reverse flow, multi chamber (can annular) combustion system is utilized. Combustion xxxxxxxx are arranged around the periphery of the compressor discharge casing. This system also includes the fuel nozzles, spark plug ignition system, flame detectors, and crossfire tubes. Crossfire tubes connect each combustion chamber to adjacent xxxxxxxx on both sides. Transition pieces connect the combustion liners to the turbine nozzles Each liner, fuel nozzle, and transition piece can be individually replaced. [GRAPHIC OMITTED]

Combustion. Waste combustion reduces the overall volume and mass of material which will ultimately require disposal. Combustion of wastes must be practiced in compliance with 40 CFR 257, which prohibits the open burning of solid waste; 40 CFR 257 defines open burning to mean combustion without 1) control of combustion air to maintain adequate temperature for efficient combustion, 2) containment of the combustion reaction in an enclosed device to provide sufficient residence time and mixing for complete combustion, and 3) control of the emissions of the combustion process. In the open burning process, waste is allowed to burn with little control of the combustion process, and there is a high potential for uncontrolled fires. During open burning, temperatures may not be high enough to destroy entirely the combustible materials. Thus, higher temperatures are preferred (generally above 1,200 °F). Incomplete combustion at low temperatures produces an ash which is attractive to scavenging animals and has the potential to produce a higher strength leachate at landfills when disposed of (Xxxxxxxx and Crimp 2004). The prohibition on open burning does not apply to facilities combusting agricultural wastes. It is noteworthy at this point to mention that the presentation of the various thermal technologies are included here for completeness of the report and is not intended to support such technologies. Communities should always evaluate and adhere to all regulatory requirements before implementing a solid waste management system. However, in general, incinerators are engineered to control the combustion process better by creating a high-temperature environment that leads to more efficient waste destruction and less air pollution, in contrast to the open burning process. Several types of incinerators - burn boxes, air-curtain incinerators, and multiple-chamber/batch starved-air systems - may be appropriate only for the occasional burning of agricultural wastes in the field, silviculture wastes for forest management purposes, land-clearing debris, diseased trees, debris from emergency clean-up operations, and ordnance. It is noted that these technologies are not allowed for municipal waste management. These incinerator types are summarized in Table 5 and described in greater detail below. Table 5.
