FIELD: carburizing. SUBSTANCE: apparatus has furnace with branch pipes for supplying hydrocarbon gas and endogenic gas, endogenic heat generator, and system for closed circulation. The reverse branch pipe of the system has branch pipe for carbon dioxide. Minimum area of cross-section and area of cross-section of the branch pipe for supplying hydrocarbon gas relate as 1: 0.8. The system is in communication with the furnace and endogenic generator. EFFECT: decreased toxicity. 1 dwg
