The best way to calculate equipment’s energy consumption is to calculate the power consumption per square meter of a given thickness sheet glass under certain loadage during continuous production.
Most energy is consumed in the glass, especially thick glass heating. However, regardless the heating technologies you may adopt, the energy needed to heat certain amount of glass to its softening point is a constant number (The law of conservation of energy). Therefore, how to reduce energy loss will determine the performance of energy-saving of a glass tempering furnace. Among all the forced convection furnaces, the ones that adopt circulation blower can most effectively lower the energy consumption of the glass tempering machine by improving the heating efficiency. In conclusion, it will be best for you to choose the equipment using high temperature blower convection.
