To improve the overall efficiency of heat recuperation in a burner installation, an additional or auxiliary heat exchanger (25) is positioned adjacent the burner (4) immediately behind a heat exchanger recuperator (12) for combustion air, the additional heat exchanger having a heat carrier medium, such as water, pressurized water, heat transfer oil, or the like, circulated therethrough for recuperation of additional heat from the exhaust gases and utilization, for example for space heating, hot water supply, or the like, in a further heat exchanger (28). The heat transfer efficiency of the burner system can thereby be improved to provide for a burner operating at for example 1000 DEG C., of final exhaust gas temperatures in the order of 200 DEG C. which, without the additional or auxiliary heat exchanger, would be exhausted at about 500 DEG C. |
