This invention relates to a single- or multilayer, oriented film formed from polyester and at least one inorganic black pigment. The ignition circuit has an ignition coil that has relatively low inductance about less than 10 henries, and a driving circuit for a multi-spark ignition sequence. Turbines are provided on the steam pipe and driven by the dry air. These financial statistics can be used to drive alarms and alerts within the process network and be used as inputs to process plant optimizers, etc.
