Abstract

Experimental studies have been made of the laws of ignition of a group of typical liquid fuels (kerosene, diesel fuel, mazut) by single particles of metals and porous particles of metal oxides heated to high temperatures. We have established the dependences of numerical values of ignition delay times of liquid fuels on the temperature of porous particles formed by welding and of monolithic steel particles in the form of disks. The experimental results show that the delay times of ignition of the typical distillate fuels — kerosene and diesel fuel — by "hot" particles formed by welding metals are shorter than for the ignition of the same fuels by monolithic steel particles of adequate sizes. The ignition delay times of the highly viscous fuel — mazut — are independent of the particle porosity.
