With the aid of microthermocouples and video recording stable combustion process of liquid nitrate esters is studied: for nitroglycerin at sub-atmospheric pressure, for nitroglycol at pressure range 0,38-1,3 MPa and for diethyleneglycol dinitrate at pressure range 0,62-4 MPa. It is established that combustion of these nitrate esters takes place according to gas-phase model, whereas combustion surface temperature is equal to their boiling temperature. It is shown that limiting reaction takes place in the first flame, in which mainly the reduction reaction of NO 2 to NO occurs.
