COMBUSTION METHOD FOR REDUCNG NOX AND SMOKE E~SSION
NOX SUFPRESSANT STATIONARY GAS TURBINE COMBUSTOR
K Morimoto, T Suzuki, Kobe, Japan assigned to Kobe Steel Ltd
A combustion method which can reduce the emission of NOx and smoke. In sharp contrast to the conventional combustion method, the method of the invention can remarkably reduce the emission of both of NOx and the smoke simultaneously, by adopting a specific flow pattern of fuel and combustion air in the combustion chamber, the pattern has been obtained as a result of studies and experiments concerning the influence of the intensity of mixing of the fuel and the combustion air on the emission of NOx.
B W, C&hold, C Wilkes, assigned to General Electric Company
The NOx emissions of a stationary gas turbine are reduced by concentrating a NOx suppressant in the reaction zone of the gas turbine combustor by dividing the flow of air to the reaction zone and the dilution zone of the combustor by means of an air flow splitter and by taking advantage of the radially stratified compressor flow. The air flow to the two zones is preferably separated by a common flow shield.

J S Perz, assigned to Martin Marietta Corporation A composition and process for improving the curing of concrete, the composition co~sing a Singapore dammar resin dissolved in an organic solvent. In a preferred embodiment of this invention, the resinsolvent solution is dispersed in a water-based emulsion by the use of an appropriate emulsifying agent. A preferred organic solvent is mineral spirits, and preferably the organic solvent contains a low enough level of phot~he~c~ly reactive liquids to meet air pollution requirements such as Los Angeles Rule 66.
