Steam Turbine and Generator Retrofitting

Steam Turbine and Generator Units Retrofitting

1. For all kinds of large, medium and small steam turbines that have been used for a certain period of time, the current advanced technology is adopted to transform their circulation parts, so that the efficiency of the old units is increased by 5%~7%, the output power is increased by about 10%, and the service life is prolonged.

2. Transforming the steam turbine that only generates electricity into a steam turbine that combines heat and power, not only has the traditional condensing unit changed to low vacuum operation to supply heat; The condensing units are drilled and transformed into non-adjustable or adjustable (adjusting the extraction pressure and flow rate) extraction condensing units. There are also our unique technologies, which transform the extraction condensing units into back-pressure units, which have the advantage of no need to transform the civil engineering foundation. In addition, there are various transformation technologies suitable for various units, such as changing large, multi-cylinder, 200MW and above condensing units into heating units.

3. Reforming the cogeneration unit

Through thermodynamic calculation, the unit is reformed to increase or decrease the inlet steam parameters, exhaust parameters, increase the flow rate and improve the power, which not only meets the needs of users for heating, but also improves the efficiency of the unit.

About 30% of the nearly 200 units sold by our company have undergone technical transformation in one or two ways above.

4. The user's original units shall be retrofitted with high-pressure front-end machines or low-pressure rear-end machines.

5. Replace the user's original condensing or extraction condensing steam turbine with back pressure unit locally.

6. For users to engage in various waste heat power generation, biomass fuel power generation, with a variety of different forms, capacity of steam turbine generator sets.
