Summary on Grant Application Form
Clean, efficient combustion in coal-fired burners requires close control of the air/fuel ratio. It is proposed to develop an acoustic mass concentration meter, suitable for monitoring Pulverised Fuel flows. A novel aspect of the proposal is its use of a wide-band of frequencies including audio-frequencies. The resulting system should be less susceptible to effects of 'roping' flow and more capable of detecting and compensating for changes in particle size distribution than single-frequency of narrow band and ultrasonic methods. The development will include investigations of non-intrusive transmission loss and orifice impedance measurements on laboratory rigs at the OU and at the University of Greenwich. Laboratory measurements will include systematic investigations of the influences of particle size and shape and comparison with predictions. The methods will be tested against controlled particulate flows in the laboratory and on known flows in an industrial setting (at International Combustion Ltd Derby). The proposal includes provision for a steering committee including representatives of relevant power industries and instrument manufacturers.
