Fire extinguishing powder is used as powder coolant and multilayer liquid is used as liquid coolant containing water or aqueous solution of mineral salt and organic liquid. Mixture is initially directed through water or aqueous solution of mineral salt with following directing through organic liquid. Apparatus has reservoir with liquid or powder coolant and chamber filled with solid fuel composition charges. Chamber is made in the form of inverted sleeve submerged into coolant. Layer of coolant cools mixture to form hydraulic seal providing pressure relieve in chamber during burning of charges. EFFECT: increased efficiency and simplified method. 4 cl, 4 dwg
