In this paper, the two kinds of hot wind igniting and combustion-supporting technique were summarized.

The paper established while achieving tinpot fuel combustion-supporting, desulfurization and denitrification by MgH2 particles in the furance temperature conditions.

The combustion-supporting technology is one of the effective methods to improve efficiency of coal combustion.

The results show that,with plasma assisted combustion,ions compound would make temperature hoist and density decline,and make good and bad effects on engine combustor assisted combustion,which should take these factors into account totally, Finally,the combustor will achieve the best effec.

The influence of plasma assisted combustion on hydrogen-air mixture is investigated and the variation laws of parameter in combustion process are studied by numerical simulation,under different initial conditions.

In order to study the effect of plasma assisted combustion,the combustion products of methane-air mixture and trend of turbulence at exit of combustor were investigated by numerical simulation and analyses.

This paper detailed the research into small sized high speed diesel engines in which pure methanol was used a substitute for their normal fuels and the glow plug as a combustion supporting device, the new type engine proving to be feasible and promising.
