Thermolflow Suite v24.0

Thermolflow Suite v24.0
This line includes Thermoflow’s most popular programs, GT PRO & GT MASTER for gas turbine-based cycles, STEAM PRO & STEAM MASTER for pure steam power plants, and RE-MASTER for repowering existing steam plants by adding gas turbines. It also includes the Plant Design Expert (PDE) program for executive-level use of GT PRO.

GT PRO and STEAM PRO are design programs, which create cycle heat balance as well as the physical design of equipment needed to implement it. GT MASTER and STEAM MASTER are simulation programs that predict performance of the plant as a function of its fixed equipment, control set-points, loads, and ambient conditions. RE-MASTER designs the new equipment needed to convert a given pure steam power plant to combined cycle, then proceeds to simulate performance of the repowered plant at off-design.

Thermoflow’s application-specific programs provide an astonishing wealth of modeling detail, yet are deceptively simple to use. Many new users, without training or time spent reading instructions manuals, can produce professional plant designs within a few hours of installing a program. Experienced users normally design a new plant in a matter of minutes.

This seemingly contradictory combination of incredible power and detail with fast, friendly ease of use is the result of thoughtful software design and tireless improvements — the fruit of over 230,000 man-hours of talent. All input variables have reasonable defaults, or may be generated by automatic procedures within the program to suit the user’s application. Non-critical inputs are tucked away into secondary tabs, readily accessible to those who want them, but virtually unnoticed by the casual user. Experienced users who choose to delve into details never cease to be amazed by their depth.

Highly flexible tools, dedicated to each application

Thermoflow\’s application-specific programs are not \”of fixed configuration\”, a misleading label promulgated by competitors. GT PRO & GT MASTER are highly flexible and can produce endless permutations and combinations of arrangements, that cover virtually any practical combined cycle configuration. Likewise, STEAM PRO and STEAM MASTER cover most practical conventional steam plant designs, and RE-MASTER covers any viable repowering arrangement. However, by their design, GT PRO and GT MASTER cannot model a conventional steam power plant, and STEAM PRO & STEAM MASTER cannot model a combined cycle.

Each of Thermoflow\’s four main Application-Specific programs has several thousand inputs, providing extensive flexibility and covering myriad details. This does not make them hard to use, since the structure and automated logic guides the user through the process in an orderly and organized fashion. A typical GT PRO run may involve changing only 30 of the inputs from their defaults or their automatically-generated values. Thus the flexibility and detail are there when needed, but do not intrude upon the user who just wants a quick heat balance design. A typical plant design can thus be created in under half an hour, but may take days with some fully flexible programs.

Engineering details, automatically and conveniently generated for each heat balance design

Users of Thermoflow\’s application-specific programs who have licensed the PEACE (Plant Engineering And Construction Estimator) module get instant equipment designs and cost and labor estimates along with each heat balance they produce. The assumptions used to create the physical design and dimensions of components, such as boilers and condensers, may be defined by the user, or left to the program’s own automated logic. This provides the flexibility for knowledgeable users to mimic actual designs created by specific vendors, while providing the convenience of automated equipment design logic for the casual user. PEACE also includes detailed pipe sizing procedures for all main steam and water pipes, as well as convenient pump sizing and specification routines.

The cost estimates generated by PEACE are “bottom-up”, adding the costs of hundreds, or even thousands, of components. The cost and field-labor hours of each component are derived from rational models that take into account the component’s features, materials, rating, size and weight. These models have been extensively calibrated by actual equipment data. This approach is in contrast to “top-down” cost estimating procedures, which start with the cost of the system and break-it down according to rules of thumb. Whereas both methods may yield the same final result for “typical” plants, the “top-down” method, by its nature, cannot be sensitive to detail design changes, so cannot be used for optimizing the tradeoffs between cost and performance. The “bottom-up” method used in PEACE can account for changes in design details, even of the secondary components, such as pipes. By finding both the cost and performance impact of each design change, the user may quickly optimize design details, such as pipe sizes, pump selections or HRSG specifications.
