Albanese, V

A method is described of improving the conductivity of particles entrained in a stream of particle-laden gas formed by the burning of coal. The particles are collected by an electrostatic precipitator which comprises treating said gas containing particles prior to contact with the electrostatic precipitator at a temperature not greater than about 800/sup 0/F with a resistivitydecreasing amount of hexamethylene tetramine or its water-soluble salts and thereafter passing the gas to the electrostatic precipitator.
