<P>PROBLEM TO BE SOLVED: To provide an effective utilization method of waste heat in incineration of waste material by which thermal energy contained in combustion waste gas formed in incineration equipment of waste such as sludge can be reused at a high efficiency. <P>SOLUTION: After carrying out heat recovery of combustion waste gas 53 formed in a waste incinerator 41 by heat exchange in an air preheater 42, air is heated by using the combustion waste gas 53 in a white smoke prevention unit 43. A part of the heated air with the obtained temperature of 200 to 300°C is mixed for white smoke prevention, and residue of the heated air is used as combustion air of unused fuel formed on an anode 61 of a fuel cell power generation facility and/or air for heat exchange of a cathode 62. Thus, the effective utilization method of waste heat is configured in incineration of waste material. By this method, a good energy efficiency is achieved and energy cost in the incineration equipment is reduced, since a surplus of the heated air for white smoke prevention that has not been used conventionally is used as the air for the combustion and heat exchange in the fuel cell. <P>COPYRIGHT: (C)2008,JPO&INPIT |
