Apparatus, system, and method for blending batch and cullet at a predetermined cullet ratio for feeding to a furnace. It includes a first hopper for holding cullet; a second hopper for holding batch; feeder associated with the second hopper; a chamber positioned to receive cullet from the first hopper, an inlet spout configured to receive cullet from the first hopper so that cullet flood feeds into the chamber to keep it constantly filled with cullet up to its angle of repose, and an outlet spout; a chute positioned to receive batch from the feeder and extending into the chamber and having a chute outlet having a diameter equal to or larger than the outlet spout; a charger for receiving mixed batch and cullet from the chamber; and a controller operatively connected to the feeder and to the charger.

A system for preheating batch materials includes a preheater, a charger, a first temperature sensor, a second temperature sensor, a valve, and a charger temperature controller. A first recirculation duct provides exhaust fluids from the charger to a second recirculation duct coupled to an inlet of the preheater. The first temperature sensor is configured to generate a first temperature signal indicative of a first temperature of fluids within the second recirculation duct and the second temperature sensor is configured to generate a second temperature signal indicative of a second temperature of the fluids within the second recirculation duct upstream of where the first temperature is obtained. The valve is configured to control an amount of fluid in the second recirculation duct that is diverted to the charger and the charger temperature controller is configured to control the valve responsive to the first and second temperatures.

A mixed raw material producing method for producing a mixed raw material includes preparing a glass raw material and an aqueous solution of sodium hydroxide; causing the aqueous solution to absorb carbon dioxide gas, to deposit sodium hydrogen carbonate in the aqueous solution; and mixing the sodium hydrogen carbonate with the glass raw material, to obtain a mixed raw material to be charged into a melting furnace.

An apparatus for the production of a mineral melt burns combustible material in the presence of inorganic material to form a melt. The apparatus includes a circulating combustion chamber which receives a fuel, pre-heated mineral material and a combustion gas so as to melt the mineral material and generate exhaust gases which are separated from the melt. The gases pass through an exhaust pipe to a conduit of a heat exchange system. The apparatus includes a quenching hood for quenching the exhaust gases by drafting a cooling fluid, such as ambient air, into the flow of exhaust gases around the exhaust pipe, and wherein the exhaust gases exit the exhaust pipe inside the hood.

A device and to a process for the preparation and charging of starting materials for a glass furnace includes a system for carrying out a mixing of starting material powder and of liquid water producing a moistened mass of starting material powder, to a system for carrying out a mixing of cullet with the moistened mass of starting material powder producing a mixture of starting material and of cullet, known as SM/C mixture, a starting material preheater in which the SM/C mixture circulates and is heated and dried in order to produce a mass to be charged, then a system for charging the glass furnace with the mass to be charged.
