Which gas turbine is the best for my combined cycle power plant conversion?

combinedcyclesThe goal of this test case is to find the gas turbine necessary to produce 58 MW of total net power for the conversion of a steam turbine to a combined gas-steam cycle while providing the highest level of cycle thermal efficiency.

The exhaust gases from the gas turbine are used to heat up steam through three HRSGs (Heat Recovery Steam Generators) in series. The steam is then used in the studied steam turbine which is comprised of two “cylinders” in series.

SoftInWay April Events and Why You Should Attend

supercriticalco2inaxcycleMarch just really flew by!

We’re kicking off April with our new Heat Balance Calculation with AxCYCLE online classes this month. Here’s three good reasons you should attend:

1. You’ll get to learn, understand and dive into our new conceptual cycle analysis tool that has built-in customizable OEM turbine and ICE libraries (perfect for engineers involved in waste heat recovery) Continue reading “SoftInWay April Events and Why You Should Attend”

Co-generation Power Plants

Co-generation power plants are very popular in Europe compared to the U.S. market. It will be interesting to see if this type of application will take off in North America, but I’d like to share a little background information on co-generation first.

Radial versus Diagonal Diffusion in Multi-Stage Pumps

Radial and Diagonal Diffusion

Although crossover design has only a secondary effect on pump efficiency, it too should use every available trick to achieve the best possible results.

This picture (left and below) shows short and long configurations of the two basic types of crossovers normally used on multi-stage pumps. Both have been tested by the West Coast pump companies and the results of these tests indicate that the radial diffusion type is approximately one point more efficient than the diagonal diffusion type. Here’s why: Continue reading “Radial versus Diagonal Diffusion in Multi-Stage Pumps”

Let’s Talk About Centrifugal Compressors

Centrifugal Compressor Design

We all know by now that no machine is perfect. Turbines have carryover losses, pumps experience cavitation phenomena, and compressors certainly have their fair share of pros and cons. We’re on the hunt for some common design problems – perhaps problems that you have experienced yourself, with centrifugal compressors. We scoured through our technical papers and presentations and searched the web for some. Here’s a list of frequent concerns and questions we ran into: Continue reading “Let’s Talk About Centrifugal Compressors”

3 Blade Design

To decrease losses and increase performance of a turbine, we need to develop special (compound) geometries. Here’s your turbomachinery cheat sheet to advanced 3D blade design!

1. Optimizing plane profiling

There are several positive things that can give proper plane sections profiling: decreasing the profile losses, decreasing secondary losses and satisfying structural limitations. Continue reading “5 Steps to Advanced 3D Blade Design”

Should You Be Implementing the Organic Rankine Cycle?

To have a successful application of an ORC system, the availability of an adequate heat source is crucial. In principal every heat-generating process, such as burning fossil fuel, can be taken as a heat source for ORC.

However, the aim is to improve energy efficiency and sustainability of new or existing applications with the focus on waste heat and renewable energy sources.

Three sectors have been identified as potential sources for the application of ORC power generation: Continue reading “Should You Be Implementing the Organic Rankine Cycle?”
