BDF – natural gas continuous monitoring system

The BDF Gas Chromatography System allows a faster and more precise melting regulation thanks to an energy balance relationship between the energy that is needed to melt the glass and the energy provided by the supply fuel

A large number of processes relating to the use of gas, such as in the glass industry, are very sensitive to varying gas parameters and must be adjusted or regulated accordingly. These needs are meet with a simple and low maintenance solution provided by a BDF Gas Chromatography System.

This small system allows a faster and more precise melting regulation thanks to an energy balance relationship between the energy that is needed to melt the glass and the energy provided by the supply fuel. This innovative mode of operation differs from the usual regulation based on the temperature of the crown.

In the glass industry, the melting process was usually controlled with a regulation based on a fixed temperature set-point of the crown furnace. Every variation of the temperature in the furnace implied a fuel flow regulation time of about one hour and in this transitory phase, the quality of the glass and the fuel consumption was compromised, resulting in wasted fuel and higher costs.

The BDF Gas Chromatography Regulating System considers the variation of the chemical and-physical characteristics continuously. This results in a faster and more accurate regulating system because it is dependent on the relationship, for a given quantity of the glass in the furnace, between the melting energy, and the fuel supply energy. From the flow-rate, density and calorific value, the system calculates the energy of the fuel flow and thanks to an algorithm; this defines how much energy the glass requires for melting.

If a variation of the characteristics happen during the operation, the system will modify the fuel flow-rate to deliver the required fuel supply energy.
