Optimal Heating

The generated products of heating of coal in airless condition are hard residue, condensed liquid and gas. The condensed liquid product or tar is one of the most important product of pyrolysis. Therefore detailed investigation on pyrolysis of brown coal and it is tar studies provide basic theoretical knowledge for further thermal processing and application of coal. Have been determined main technical characteristics and elemental composition of the analytical sample of Aduunchuluun coal. The pyrolysis experiments have been performed at different heating temperatures (550-600oC) and determined the yields of pyrolysis products. The optimal heating temperature of pyrolysis of Aduunchuluun coal was chosen 500oC in which the yield of tar was higher (32%). The purified tar was subjected for FTIR analysis. Also the tar organic bases and organic acids are separated from the tar and the residual neutral fractions of pyrolysis tar were divided in to several fractions including aliphatic, aromatic and polar. And these fractions analyzed by GC/MS analysis and the determined most important organic substances are derivatives of benzene, naphtha-lene, phenols and alcohols.

The paper examines the integral characteristics (minimum temperature, ignition delay times) of stable combustion initiation of organic coal-water fuel droplets (initial radius is 0.3-1.5 mm) in the oxidizer flow (the temperature and velocity varied in ranges 500-900 K, 0.5-3 m/s). The main components of organic coal-water fuel were: brown coal particles, filter-cakes obtained in coal processing, waste engine, and turbine oils. The different modes of soaring and ignition of organic coal-water fuel have been established. The conditions have been set under which it is possible to implement the sustainable soaring and ignition of organic coal-water fuel droplets. We have compared the ignition characteristics with those defined in the traditional approach (based on placing the droplets on a low-inertia thermocouple junction into the combustion chamber). The paper shows the scale of the influence of heat sink over the thermocouple junction on ignition inertia. An original technique for releasing organic coal-water fuel droplets to the combustion chamber was proposed and tested. The limitations of this technique and the prospects of experimental results for the optimization of energy equipment operation were also formulated.
