The proposed convection heating equipment with forcible circulation and a process of heating glass sheets by employing this heating equipment comprises a jacket (20O) with an internal zone, a conveyor belt for transferring the glass sheets through said internal zone, a gas burner (204) being operably coupled with the jacket (200) for producing hot combustion products and consequently assurance of heat input into the system. Said gas burner (204) inlet is operably coupled a controller (210) for controlling intensity of the heat input and through the mediation thereof holding temperature on a predetermined selected value. In addition thereto the system is provided with at least one speed controller for controlling velocity of impingement of working liquid onto upper and/or lower surface area of a glass sheet within the jacket internal zone. Said velocity of the working liquid impingement and through the mediation thereof the intensity of heat transmission by convection between the working liquid and the glass sheet, too is controlled independently on heat input introduced into the system.
