Oxygen enhanced incineration

A similar technology called Oxygen-Enhanced Sludge Incineration was involved in a 5-month study conducted by Praxair and the New York State Energy Research and Development Authority (NYSERDA). This study was carried out at Monroe County s Erank E. Van Fare Sewage Treatment Plant in Rochester, New York. One of the facility s two 11-hearth furnaces was converted for use with oxygen for the test. The total cost of this study was 400,000 (D229170, p. 1). 

The second case to be considered is designing a new incineration process to include oxygen enhancement. The savings in capital equipment may be very substantial. The incinerator itself can be smaller, for a fixed processing rate, compared with an air/fuel system. The associated downstream equipment may be smaller as well.

The high temperature gas resulting from the oxygen-enhanced combustion of trash is more useful for the generation of electricity than is the relatively cooler gas generated from incineration of trash with... 

In the summer of 1987, the Oxygen Combnstion System (OCS) was used to enhance the performance of the U.S. EPA s Mobile Incineration System. The OCS, along with other system modifications, helped double the feed rate of the MIS. According to the ERA, material processing costs were reduced from 2800 per ton before OCS installation to 1100 per ton after installation...
