Energy is usually the fourth biggest operational cost for an industrial enameling plant after respectively amortization of equipment, enamel consumption & labor cost.**
For this reason it is important to pay attention to the energy consumption of various enameling machines when purchasing new equipment and to consider investments in energy saving measures and/or heat recovery equipment for existing equipment.
Last-but-not-least it is important to keep your enameling equipment in a good condition by regular preventive maintenance and operation with the appropriate settings.
Below a short presentation about energy savings at industrial enameling plants
** In countries with relative low labor cost, energy might even be the third biggest enameling cost.
A clean furnace atmosphere is important for obtaining good enameling results.
Elevated concentrations of CO2 and/or H2O may slow down the emission of gases from the metal substrate thru the enamel layer during the fusion stage and under certain unfavorable circumstances result in enameling defects such as pinholes & fish-scales.
CO2 & H2O may accumulate inside the furnace, if the combustion system is leaking and/or the forced abstraction of combustion gases is not sufficient.
