''Hydrate Addition at Low Temperature'' or HALT is a dry calcium-based hydrate injection process for the removal of SO/sub 2/ from flue gases off a sulfur bearing fuel. In this process the hydrate is pneumatically conveyed and injected into the flue gas stream as a dry particulate. The flue gas is cooled downstream of the hydrate injection by spraying the gas with a stream of finely atomized water droplets. The water is atomized into a fine spray by using air under pressure as the atomizing fluid. The spray nozzles are specially designed. Results are presented on nozzle array field tests conducted using the Dravo HALT unit at Ohio Edison's Toronto station. A method for humidifier scale-up from single-nozzle pilot test data was demonstrated. The method uses arrays of nozzles, with each individual nozzle operated at fixed conditions determined as optimum in the single-nozzle tests. By applying this method, the Consol 8.3-inch pilot humidifier operation with a single Spraying Systems 1/8JJ-J12 nozzle was successfully scaled up to operation of the Dravo 31 x 31-inch humidifier with arrays of up to 46 J12 nozzles. The tests provided data on nozzle deposition and solids dropout that may be useful for large-scale humidifier design. 4 refs., 16 figs., 10 tabs.
