Title:
低減された排出量での微粉炭の燃焼方法
Document Type and Number:
Japanese Patent JP2007531797
Kind Code:
A
Abstract:
Fuel compositions containing (a) pulverized coal; and (b) an oxygenate selected from glycerol, glycerol derivatives, propylene glycol, propylene glycol derivatives, ethylene glycol, ethylene glycol derivatives, fatty acid alkyl esters, fatty alcohols, and mixtures thereof. Methods of reducing the NOx emissions generated from the burning of pulverized coal in a heat-producing unit, wherein the method comprises the steps of: (a) introducing pulverized coal into a combustion chamber of the heat-producing unit; and (b) co-firing the pulverized coal with an oxygenate source selected from glycerol, glycerol derivatives, propylene glycol, propylene glycol derivatives, ethylene glycol, ethylene glycol derivatives, fatty acid alkyl esters, fatty alcohols, and mixtures thereof, where the combustion of the oxygenate source generates at least 2.5 %, on a heat input basis, of the total heat generated by the co-firing.
