INSTALLATION FOR AERODYNAMIC HEATING OF LONG-SIZED ARTICLES Russian patent published in 2001 - IPC

FIELD: heat engineering. SUBSTANCE: installation has a heat-insulated chamber, in which the partition is installed in its longitudinal axis with separation of it into the working passage for placement of the article and the pressure passage - for injection of the heat-transfer agent to the working passage, it is made for varying the heat-transfer agent circulation circuit and for flowing through it of the heat-transfer agent from one passage to the other, and an opening is made in the bottom of the heat-insulated chamber in its central part joined to which with formation of a single heat-transfer agent circulation circuit an additional heat-insulated chamber accommodating a rotor heater communicating through its suction part with the working passage, and through the injection part - with the injection passage. EFFECT: improved control of the degree of heating in article length with a high uniformity and intensity. 9 cl, 6 dwg
