| Summary: | Title screen The paper examines the integral characteristics (minimum temperature, ignition delay times) of stable combustion initiation of organic coal-water fuel (OCWF) 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 OCWF were: brown coal particles; filter-cakes obtained in coal processing; waste engine and turbine oils. The different modes of soaring and ignition of OCWF have been established. The conditions have been set under which it is possible to implement the sustainable soaring and ignition of OCWF 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. We have proposed and tested an original technique for releasing OCWF droplets to the combustion chamber. We have also formulated the limitations of this technique and the prospects of experimental results for the optimization of energy equipment operation. |
