Abstract: Present Invention discloses new combustible mixture and fuel, which during burning releases energy 15 times greater than that of lignite and 4-5 times than that of coke. The combustible mixture consists of the liquid and solid phases, where the solid phase comprises: aluminium powder; at least one M1X2, where M1 can be any metal in oxidation state +2, and X can be any halogen; M2CO3, where M2 can be any two-valent metal; zinc ammonia chloride, SiO2 in the form of quartz sand; and quick lime; whereas the liquid matter comprises: at least one C1 to C6 carboxylic acid, or at least one anhydride of the mentioned carboxylic acids, or at least one its ester or amide; methylcellulose; and formaldehyde, or its commercially accessible solution—formalin; and water. Fuel is made when the combustible mixture is hermetically closed in a container.
