Abstract

The article discusses the coal-water fuel obtained from coal of Shubarkul. Assembled experimental setup for sustained combustion of the liquid fuel. The use of vortex technology allows to simplify the system of preparation of fuel, increase its productivity, to ensure explosion safety, reduce the cost of preparation of fuel for combustion; to stabilize the ignition and combustion and to refrain from lighting the torch gas or fuel oil even when burning low-grade fuels. The technology is designed to create effective technology of sludge processing Shubarkul coal deposits located in the Karaganda region. For efficient combustion of coal-water fuel the original design of a burner containing predtopochnyh chamber for igniting the hydrocarbon fuel received by electrohydropulse processing from slimes of the Shubarkul coals. Vortex pretopos allows you to burn both HLA and other types of liquid fuels: diesel, fuel oil. The boiler is equipped with vortex preopcom, implies the possibility of using a backup fuel in addition to coal-water fuel. Vortex chamber or pretopos to burn has a width of 100 cm and a height of 110 cm, it is made walls out of direct fireclay brick with a wall thickness of 10 cm the Regulation of the distribution of blast is carried out a viewing window with a slide valve and is controlled by the pressure of the secondary air fan. The principle of operation of vortex precopy based on what is generated inside the combustion chamber the vortex keeps large particles of fuel within the chamber to complete the burning of combustible substances. The feature of the vortex furnace is the configuration of the combustion chamber, which is close to the radial, and the tangentially supplied combustion air jets, creating additional impetus for the formation of vortex motion of the burning fuel particles and gases. Using a measuring device for determining the intensity of combustion defined temperature combustion of coal-water fuel. The highest temperature of combustion achieved in 1400 ºС.
