Software Package for Forced Draft Units Calculations for KMZ JSC — Stage 2

We continued working on the development of the calculation system for KMZ. At this stage, we developed a calculator of the initial parameters that are in use in the system for plotting the aerodynamic characteristics of the forced draft units and the gas-dynamic characteristics of the superchargers.

For calculation of the initial parameters of the forced draft units’ handled medium, a separate module (calculator) is implemented where 4 calculation models are integrated at the moment. The main purpose of the calculator is the calculation of the unit’s input density and adiabatic index as a function of the composition of the handled medium and parameters of its condition based on one of the models selected.

Technology Stack Used

The main technology stack remained the same, namely:

  • C# programming language
  • MongoDB non-relational database

System Architecture

Since at the beginning of development we used the modular architecture, we had little difficulty adding a new module in the system previously developed and carry out a slight integration. Now, the architecture of the application is as follows.

Result of work performed

The characteristics of gases used in the calculations of the initial parameters are included in the program as a set of separate constants, arrays of data and coefficients of the interpolation formulae and can be changed in course of the calculation. There is a feature enabling to import the data on the gaseous component in use in JSON format.

The calculator is meant to be used in the calculation of the initial parameters of the following gases:

Atmospheric and aspiration air.

Flue gases of thermal power stations.

Process and exhaust gases of the metallurgical and chemical production facilities.

Gas of unknown composition with specified characteristics.

Should any parameters change, the parameters will be automatically recalculated in the system interface. Also, error reporting is implemented (if there are incorrect values in the input data or if they are beyond the tolerance range).

KMZ JSC offers a wide range of products in the field of industrial gas purification, energy-efficient smoke exhausters and superchargers to its customers. The experience accumulated and highly qualified technical specialists enable us to solve the tasks as accurately as possible, using state-of-the-art technologies in the field of moving gas-air mixtures, upgrading outdated equipment, increasing of service life and reducing maintenance costs.

Customer’s review

KMZ JSC develops and manufactures large forced draft units and fans. At some point in its development, KMZ JSC needed to introduce automatic preparation of technical and commercial offers for the Customers to reduce the time of documents preparation and to systemize data. The task included several stages, such as fan picking accompanied with aerodynamic characteristics plotting, calculation of acoustic characteristics, drive picking, determination of future unit’s physical properties, determination of the complete set based on the Customer’s needs, fan sketch forming, assessment of cost and, consequently, technical description of the offer prepared.

To complete the project of KMZ JSC, MST Company was picked, because its staff included specialists capable of solving the tasks set.

During the completion of the project, we had to implement mathematical algorithms and graphical solutions, and also to implement the automatic preparation of technical and commercial offer based on the modular approach. The development of the software interface was just as important. The project was implemented in stages. Each module implemented was provided to us at once for testing. During the implementation of the project, the matters were solved within short timeframes. Some terms of the technical assignment changed during the testing, and MST Company showed understanding of this. Consequently, our software was successfully completed.

I am thankful to MST Company for their professional competence and flexible approach to the solution of non-routine tasks!
