Abstract

The method involves generating a gas stream to be directed towards tubes (2) of a furnace (1), and producing solid particles (6) from a composition constituted of ninety five percent of urea. The solid particles are integrated with the gas stream and the particles are projected at a speed such that they disintegrate when they contact the tubes. The gas stream and the particles are moved along the tubes.
