The project will investigate the feasibility of adapting a novel water spray nozzle for inclusion in an industrial wet scrubber designed to reduce particulate and flue gas emissions. Initial consideration indicates that the properties of the aerosol spray hold significant advantages over conventional methods which will lead not only to a technically better system, but also to significantly reduced running costs. However the spray characteristics must be quantified fully to overcome present manufacturing difficulties and to maximise the benefits of the design. Specifically, a significant cost reduction along with increased efficiency may be achieved through better water droplet characteristics. This is particularly true if employed as part of a chemical spray system where large savings can be made if the total volume of flow (due to smaller droplet size) can be reduced. The work programme will seek to quantify the spray characteristics from the nozzle and to propose refinements to meet the needs of the new application. Further tests on a laboratory scale chimney will demonstrate the efficiency of the spray in comparison with other systems. It is expected that such a device will meet the demands of the philosophy embodied within BATNEEC: Best Available Technology Not Entailing Excessive Cost, first used in the EC Framework Directive on Combating Air Pollution from Industrial Plant (84/3601EEC). Thus significant markets are envisaged if efficiency gains and cost reductions can be achieved, with consequent benefits to pollution control within the Community.
