Steam Turbines

This condensing multi-stage turbine is a high-efficiency, high-output type capable of converting the heat energy of steam to mechanical energy without waste, converting turbine exhaust pressure as a vacuum.

This series is known as a multi-stage type, featuring at least two turbine blades attached to the shaft. The number of turbine stages and the average pitch diameter of these turbine blades are determined optimally in each case, depending on factors such as output, number of revolutions, intake steam pressure, temperature, exhaust pressure, and so on.

According to the number of stages selected, the nozzles, wings, turbine blades, shafts, housing, etc. are all subject to change, but all other essential parts are completely standardized and designed for easy attachment to any model. In addition, we maintain an abundant inventory of these standard parts and manage these to ensure they can be supplied quickly and reliably.

To improve turbine efficiency, we increase the annular area of the wing and reduce exhaust losses by lengthening blade length for the row of blades in the last stage. Speeding up the turbine and reducing the number of turbine stages are also effective for reducing the initial amount of investment.
For our high performance steam turbine with interacted shroud-type blade, we increased the annular area of the final stage’s row of blades to 1.6 times that of the conventional machine, and achieved a high-speed rotation of 125% with the same performance as the conventional model. As a result, given this emphasis on efficiency, this machine is more efficient than conventional machines at a lower price while providing the same performance as conventional machines, prioritizing selection for initial investment value.

In recent years, environmental problems caused by global warming have resulted in calls for energy conservation, and fields of renewable energy such as biomass, cogeneration, and solar power are now being promoted. This model is often used for power recovery in such fields.

There are countless applications in other fields as well. As well as power generation for IPP (independent power production) and combined cycle plants, these turbines are suitable for private power generation across a variety of industries, including petrochemical production, petroleum refining plants, driving high-speed gas compressors in ammonia and ethylene plants, as a water supply pump for high-temperature high-pressure boilers as well as boiler induction fans, forced draft fans, as a compressed air source for plants and factories to drive compressors, and in sugar factories, paper mills, plywood factories, and others.
Also suitable for use with API standards 611, 612.

The axial exhaust type is an improved system with easier layout for developing condensing steam turbines. Although conventional condensing steam turbines orient the exhaust flow downward or upward in a direction perpendicular to the axis for return to the condenser, exhaust loss can be reduced by directing the exhaust along the direction of axial flow, which greatly improves energy efficiency.

Also, in terms of layout, the conventional design requires more space in the downward or upward direction. Our axial exhaust turbine is designed to discharge the exhaust axially and connect to the condenser directly, making layout easier. This can drastically reduce installation costs, and can greatly contribute to reduction of time and costs for maintenance and inspection.

If steam is extracted from the intermediate stages of the turbine and sent to the factory, it is possible to achieve steady pressure from low turbine loads up to the specification by controlling internal extraction pressure.
Internal extraction pressure control is a method that uses a pressure control valve installed inside the casing of the turbine to perform pressure control on the “upstream” side of the valve, keeping extraction pressure constant.

Since up to 2 internal control valves can be installed, it is possible to extract two steam supply lines (medium-pressure steam, low-pressure steam) for the factory from a single turbine.

Back pressure turbines utilize the pressure differential between the intake steam and the expelled steam to efficiently convert part of the thermal energy of the steam into mechanical energy. The exhaust pressure is designed to be higher than atmospheric pressure, and the heat energy of the exhaust steam is reused for the factory’s processes.

Both the H series and the high-output, high-speed compatible HO series are single-stage, horizontally-installed compact general-purpose turbines. Our product range also includes the high-speed rotation-compatible CC series (also single-stage and horizontally-installed) for use with compressors, etc. The vertical-type V series is also available.

Mainly used for pumps, fans, compressors, mills, and shredders in various factories such as petroleum plants, chemical plants, sugar mills, and power plants.
The H, HO, V series are suitable for use with the API 611 standard, while the CC series is suitable for use with the API 612 standard.
