Abstract

Brown coals are valuable natural resource. Brown coals of the Kara-Keche deposit are most of all ready for industrial development in the Kyrgyz Republic. To solve the problems of effective development of brown coal of this deposit, it is necessary to study the issues of direct combustion of water-coal fuel (WCF) without thermal stabilization of the flame with additional sources of heat release. Experimental studies of WCF combustion have been conducted at the experimental industrial technological stand of Siberian State Industrial University, Novokuznetsk city. Structural-rheological and thermal characteristics of a pilot batch of brown coal of the Kara-Keche deposit, as well as data on the organization of efficient combustion of WCF, have been obtained. Brown coal of the Kara-Keche deposit meets the requirements of pipeline transportation and direct combustion in the furnaces of boilers of thermal power plants and boiler houses. The resulted water-coal fuel of brown coal is effectively burned in a vortex adiabatic furnace and the combustion process is like the combustion of WCF of hard coals of “G” type.
