FIELD: chemistry.
SUBSTANCE: fuel composition contains 50-60% chromium oxide, 20-25% aluminium powder and alumina (aluminium oxide) powder - the rest. The metallothermic fuel burns without atmospheric oxygen and without formation of harmful emissions, i.e. is environmentally safe. The combustion wastes are not toxic. When burning a mixture with such composition, ambient temperature rises to 1200°C in 50 seconds, which is very suitable for hearths.
EFFECT: fuel is 5-7 times cheaper than the hydrocarbon equivalent.
