1 kw steam turbine generator

Types of 1 KW Steam Turbine Generators

A 1 KW steam turbine generator transforms the energy in steam into electrical energy. These machines come in several designs.

• Axial Flow Turbines

  The axial flow turbine is the most popular turbine generator design for large power plants. In this design, the working fluid flows in an axial direction, parallel to the main shaft of the turbine. An axial flow turbine has several stages. Each stage has nozzles and buckets. Steam flows through the nozzles, and by the impulse mechanism, it acquires velocity first and then strikes the buckets. The velocity change in the steam causes the shaft to rotate. The nozzles in the stage determine how effective the stage works. The more stages the turbine has, the more efficient it is at converting steam energy into rotational energy.

• Radial Flow Turbines

  In radial flow turbines, the working fluid moves perpendicular to the central shaft of the turbine. Steam expands from inward to outward in a circular disc or wheel. Radial flow turbines are simpler than axial flow turbines. Also, they have fewer parts. Because of this, radial flow turbines are suitable for small-scale power generation. Some applications are geothermal, biomass, and concentrated solar power plants.

• Impulse Turbine Generators

  Impulse turbines change the momentum of steam to do work. The steam nozzles accelerate the steam, and the moving steam strikes the turbine blades. The impulse turbine generator has a rotor, and it works with one or more cups fixed at a distance along the rotor. The steam jet moves the cups, and they rotate the rotor. The cups can have different shapes, such as a straight cup with a curvature or a cup with a 'U' shape. Straight cups are simple to make and model in CFD software. Although they have lower efficiencies, their performance is good in higher impulse pressure ratios. Cups with a curvature and 'U' shape have better performance in lower pressure ratios.

• Reaction Turbine Generators

  Reaction turbines are similar to impulse turbines. However, impulse turbines have nozzles that act as jets for the steam to hit the blades. On the other hand, reaction turbines have blades with chambers that reduce the pressure of the steam inside them. The reaction turbine works directly with the pressure drop and the reaction inside the chambers. These turbines are more complex than their brothers. They also have more parts. According to many experts, reaction turbines are better to produce energy in high flow rates.

Specifications & maintenance of 1 KW steam turbine generators

The specifications of the 1 kW steam turbine generator are varied according to different brands, models, and types. Paying attention to the parameters listed below is helpful for understanding its performance and capabilities, which will also affect maintenance requirements.

• Design and structure: These small turbines are generally made of iron, carbon steel, stainless steel, brass, or aluminum alloys, etc. Their blades can be fixed or moveable. The fixed blades are machined and evenly installed on the casing. Some turbines will have upper and lower casings of a certain shape to accommodate the fixed blades. The rotating ones are slightly more complicated. Firstly, there are several round discs with a certain perimeter that are processed to have grooves on the peripheries. Secondly, the shafts are inserted into the discs, and the shafts ends are also machined with grooves. Finally, the shafts and discs are interlocked. The interlocked strategy could ensure that the discs rotate with the shaft. Finally, the moving blades are assembled on the shafts that have grooves, which is the more common method. Moving blades look similar to fixed ones, but they have a more complex structure. The materials and designs of blades may vary based on the specific type and working principle of the steam turbine generator. Buyers can consult manufacturers for more details.
• Type: According to the connection method, an 1kw steam turbine generator connects to the steam source through a condenser or directly to the outlet of the steam turbine. That means it is either a back-pressure steam turbine generator or an extraction steam turbine generator. Back-pressure turbines discharge steam at high pressure through the condenser, while extraction turbines extract steam at intermediate pressure for external processes. They are also axial or radial turbines. In axial turbines, steam flows parallel to the turbine shaft, while in radial turbines, it flows perpendicularly to the shaft. A turbine with an axial layout is larger than a turbine with a radial layout under the same power. In appearance, working principles, internal structures, and other features, small steam turbines are always comparable to big ones. They usually have a more cost-effective, efficient, and simpler mechanism.
• Output power: The output power of small steam turbines are from 1KW to 20KW.

Generally, small-scale turbines are easier to maintain than large-scale ones. But frequent checkups and cleaning are still required to keep them in good condition. The first thing is to read the instruction manual to ensure the proper use and maintenance. The adjustments and repair procedures are only for trained professionals. Developing an inspection and maintenance program and checking all the components regularly is a good idea. Cleaning the components of the turbine generator, including the blades, etc., can also improve the efficiency and prolong service life. Another essential thing is to monitor the performance and output regularly to detect and deal with potential issues in time to avoid damage.
