Starship drives fan power expansion

Rapid economic expansion in China's industry has created huge demands on electrical power; this has resulted in a massive rise in the construction of new fossil fuel power stations across the country. These Power station boiler applications require highly efficient and reliable air preheaters to ensure optimum boiler performance.


As the preheater slowly rotates, at around 1-2rpm, the elements collect heat in the hot gas stream and then transfer it to the cold air stream. Preheating the air leads to a more efficient boiler performance. Renold Gears manufactures and supplies, from its factory in Rochdale, two solutions as the drive for the preheater. Both units have multiple inputs which give a resemblance to a starship.


The first is a shaft mounted gear unit, based upon the TW series, which is fitted to the central main shaft of the preheater fan and fixed into position using huge shrink disc couplings. The second option uses a design based upon the HC series. It is a two stage helical unit with a bevel gear first reduction, mounted with three first reduction bevel gears, giving three separate input drive shafts. These input shafts are separately coupled to primary drive, in-line helical, foot mounted, double reduction geared motor units from the RP range.
