<p>The method involves measuring a pH-value of liquid baths (2) by a pH-value-sensor (5). A water level of the liquid baths is monitored and corrected by a water level sensor (7), where the water level is corrected by a valve (8) and/or a compensation pump. Control and/or monitoring of a circulation pump (4), pH-value-sensor, adding device (6), water level sensor, valve and the compensation pump is performed by a control device (9). A closed circuit is formed by a quench (1) and the liquid baths. An independent claim is also included for a device for purification of exhaust gas of a heating system.</p> |
