<p>A liquid spraying system (10) having a spray header (12) and a recirculating liquid supply system for directing pressurized supply liquid to the spray header (12) with a portion of the liquid being directed from the spray header (12) as a discharging spray (15) and a portion of the supply liquid exiting the spray header (12) as a return liquid (71b). The liquid supply system includes two separate selectively pressurizable liquid containable tanks (70a, 70b) each having a respective fluid conduit coupled to the spray header (12). The liquid supply system has a first cycle of operation in which the first tank (70a) is pressurized and the second tank (70b) is depressurized so that pressurized liquid is supplied from the first tank (70a) to the spray header (12) and return liquid (71b) is directed to the second tank (70b), and a second cycle of operation in which the second tank (70b) is pressurized and the first tank (70a) depressurized so that liquid is supplied to the spray header (12) from the second tank (70b) and return liquid is directed to the first tank (70a).</p> |
