HEATING DEVICE WITH FORCED CONVECTION AND METHOD OF HEATING IN IT OF SHEET GLASS Russian patent published in 2000 - IPC

FIELD: construction, particularly, devices and methods for heating of sheet glass with forced convection. SUBSTANCE: heating device with forced convection has body with internal space, conveyer for transportation of glass sheet through body internal space, gas burner connected with body for controlled production of hot gaseous combustion products to ensure heat supply to device. Regulator is connected with gas burner to regulate supply of gas fuel and maintain temperature of working medium at preliminarily selected level. Provision is made for, at least, one regulator for regulation of reflection rate of working medium from upper and/or lower surface of glass sheets. Reflection rate and, thereby, rate of convection heat exchange between working medium and glass sheet is regulated independently from heat supply to device. EFFECT: provided separate regulation of refraction rate of working medium from glass sheet surface subject to heating irrespective of regulation of heat supplied to system. 23 cl, 7 dwg
