DETERMINATION OF KINETIC CHARACTERISTICS OF SOLID FUEL.

The combustion process begins with the ignition of fuel - bringing it to auto-ignition temperature, which is one important components kinetic characteristics fuel.
 Fuel does not occur immediately but after a certain period, during activation energy accumulated: heat or active centers, depending on mechanism thermal-kinetic chain-kinetic, sufficient overcome potential barrier. At same time, period reaching self-ignition temperature induction this reactive system: for time ignition.
 purpose work substantiate fuel: and methods their experimental determination solid fossil fuels biomass waste.
 According methodology, an installation was created in layer.
 Studies such as anthracite, hard coal, buckwheat husk, millet, oats, flax husks, birch wood, peat, paper showed dependence degree metamorphosis volatiles. With increase metamorphism decrease volatiles fuel, increases. However, depend size its particles, number layer oxidizer.
 above allows us conclude that depends only conditions exchange (accordingly, aerodynamics), absolute value infinite space, absence jet stream, constant value, then, presence (with velocity gradients) , takes another value.
 It found initial process, decreases increasing temperature. This due more intensive transfer particles gradient acceleration development oxidation reaction.
 shown by conducted experiments, particles. can be explained fact rate thermal destruction close heating. burning coal contrary, particles.
 Expressions determining autoignition were obtained based processing results experiments.
 used technologies, main ensures mode when contact oxidizer.
