FIELD: heating systems, drying. ^ SUBSTANCE: invention refers to metallurgy, and namely to devices used for drying metal parts. Device consists of independent inclined heat-insulated boxes with inlet and outlet windows, which are installed on support columns angle-wise to each other with minimum clearance at the inlet section. Besides, device is equipped with heat-insulated heating gas chamber which is located under boxes and connected with last stacks; at that, gas chamber consists of gas burner devices and ignition devices, and stacks - of secondary air nozzles. As natural gas combustion products used as heat carrier in the device and prior to their supply to boxes there preliminarily added is secondary air; at that, heat carrier is divided in the box into two flows in mutually opposite directions. ^ EFFECT: improving economy of the device owing to reduction of costs required for energy consumption, and improving metalware drying quality. ^ 3 dwg |
