Abstract
The utility model relates to an industrial steam turbine system for driving a draught fan in a thermal power station, which comprises an industrial steam turbine house, industrial steam turbines and a matching device. The industrial steam turbines for driving two draught fans of a single machine unit and the matched device are concentratedly placed in one industrial steam turbine house which is arranged under a dedusting rear flue, and an industrial steam turbine civil construction structure is combined with the dedusting rear flue support of a power plant into a whole. The turbine steam turbines adopt upper steam discharging mode, two industrial steam turbines share the same condenser which is arranged above 0 meter, and a bridge crane is arranged in the industrial steam turbine house. The industrial steam turbine system for driving the draught fan in the thermal insulation power station is unique, requires no more floor space compared with a draught fan utilizing a motor driving system, and is more reasonable in large member overhaul lifting space and operation routing inspection space.
