FIELD: methods of forming nitrogen-controllable atmospheres used for heat treatment of metals; metallurgy and mechanical engineering.
SUBSTANCE: proposed method includes incomplete combustion of hydrocarbon fuel, adsorption cleaning of combustion products from carbon dioxide at closed system of restoration of absorbent properties and adsorption cleaning from moisture vapor. Then regeneration and cooling of adsorbent are performed by blowing with hot and cold gas-shielded atmospheres, respectively. Mixture of hydrocarbon gas and commercial nitrogen is additionally delivered to combustion chamber. Commercial nitrogen is delivered is the amount of 20-40% of volume of controllable atmosphere. Hydrocarbon gas is delivered in the amount of 4-7% of initial volume of hydrocarbon fuel.
EFFECT: low cost of process; increased productivity; reduced specific consumption of hydrocarbon fuel.
