DG 4-Pole Turbogenerators Equipment supplied to over 130 countries. Over 120 years of electrical experience.

21MW gas turbine driven generator with a multi-stage air inlet filter system. Packaged generator with closed circuit cooling through a top-mounted air-to-air heat exchanger. BRUSH DG salient pole rotor, air cooled generators are extensively used in public utility, cogeneration, CHP, industrial and offshore applications. These generators are designed to be driven by both steam turbines and gas turbines, with extensive operational experience of both applications. BRUSH has more experience of the use of gas turbines than any other generator manufacturer in the world and has also supplied machines...

Rotor The rotor of a BRUSH DG turbogenerator is manufactured from a one-piece forging of high quality alloy steel, which is de-gassed, vacuum poured and stress relieved to obtain a uniform material which has excellent tensile properties. unsuitably contaminated environments may necessitate the use of a closed air circuit machine, where the hot exhaust air is cooled by a secondary coolant before being returned to the inlet. The secondary coolant is usually air or water. Excitation System The four individual coils of the rotor winding are built up from copper strips, brazed to each other by means...

The BRUSH DG range of turbogenerators has the following features: Simple foundation design for economic and speedy civil work. Minimum number of individual power station components, offering substantial savings on expensive site time. All units are fully factory tested, reducing commissioning to proving interconnections and combined turbine/generator testing. Heavy duty design, with modular construction giving a fine balance flexibility and standardisation of components for fast economic Fully developed system readily adapted to any turbine design. High efficiencies, resulting in low life cycle...
