<p>An exhaust gas purification device comprising a rotary type heat accumulator (4) rotated by a turbine (1). An NOx absorbent is carried on this heat accumulator (4). The exhaust gas discharged from the turbine circulates in the heat accumulator via an exhaust duct (10), and at this time, the heat accumulator is heated and, at the same time, NOx is absorbed into the NOx absorbent. Air discharged from the compressor (2) is heated when circulating in the heat accumulator (4) and is subsequently fed into the combustion vessel (5). When the fuel is supplied to the air to be fed into the heat accumulator and becomes a rich gaseous mixture, NOx is released from the NOx absorbent. <IMAGE></p> |
