Аннотация

An experimental study has been made of the process of ignition of single drops of water–coal and organic water–coal suspensions and coal particles heated by the oxidizer flow. The low-temperature (400–600°C) regime of the initiation of combustion of commensurate (from 1 to 3 mm) drops of water–coal and organic water–coal suspensions and coal particles has been considered. With the use of a high-speed (up to 105 frames/s) video camera and Tema Automative software, the influence of the oxidizer temperature, the gas flow velocity, the size of suspension fuel drops, and the coal particle size on the conditions and integral characteristics of the induction period has been determined. The ignition delay times and the duration of the combustion process of the investigated fuel samples have been established. The features of the stages of stable low-temperature initiation of combustion have been determined.
