摘要：A heating system for a building comprises a boiler 100, radiators 96, 110 and asecondary heat exchanger 104. Return water from the radiators 96 is circulated through afirst core 102 to cool flue gas from the boiler 100, returned to the boiler 100 or part of itdirected to a further radiator 110 and to a further heat exchanger 114 to heat ambientair for the boiler 100 and then back to a second core 116 at a temperature well belowthe dew point of the water vapour in the flue gas. Second core 116 is submerged in areservoir 120 for water 122 at a temperature well below the dew point of the watervapour in the flue gas, the water 122 level being governed by a weir 124. Water is drawnout via pump 124 to a manifold 126 having orifices and mixed with the flue gases forsubsequent cooling whilst passing down a tortuous path through a plurality of horizontalspaced apart baffles 128. The cooled gas leaves through flue 130. Water 122 collects inreservoir 120. The water may become acidic since sulphur dioxide in the flue gas may beremoved. The acidity of the water 122 may be removed by a neutralising cartridge 132which may be rechargeable. The pipework 134, pump 124, manifold 126, baffles 128, core116 and the interior of the secondary heat exchanger may be coated with a material not

affected by sulphurous acid.
