Title:
METHOD OF COMBUSTION OF FINELY DIVIDED COAL
Document Type and Number:
WIPO Patent Application WO/1987/003066
Kind Code:
A1
Abstract:
A combustion method, which comprises burning finely divided coal at a certain temperature (t) using a combustion support gas having a certain oxygen concentration (C) to obtain a stable flame of 2000oC or above. The combustion support gas is pre-heated, or both the combustion support gas and the finely divided coal are separately pre-heated and mixed upon combustion. In the pre-heating step, pre-heating is conducted so that the temperature (T) of the combustion support gas satisfies the following conditions: T>=exp{14.14 - 1.84$(1,3)$nC-exp(0.01127t - 3.444)}.
