ElectroTechnik Jet Draught refers to the Draught created by using a jet of steam. The steam generated by the boiler can be used for this purpose. The jet of steam is used to create an airflow which will cause the flue gases to exit through the chimney.
Transformers Supplier Philippines - Meiji Electric· According to the Business Dictionary, a transformer is a device that converts an alternating (A/C) current of a certain voltage to an alternating current of different voltage, without change of frequency, by electromagnetic induction. A 'step up' transformer receives a low voltage and converts into a higher voltage, and a 'step down' transformer does just the reverse.
