Increase efficiency in steam networks through continuous improvement!
From this structured analysis of the installed steam network, the MIYAWAKI engineering team derives possible optimization measures. Typical results include the following topics:
• Replacement or repair of steam traps • Re-structuring of pressure reductions
• Replacement of incorrectly designed fittings and components
• Use of residual heat through steam expansion or transfer to low- temperature processes
• Coupling of heating and cooling systems
• Conversion from steam to other heat transfer fluids
The system analysis is carried out in 4 stages
Steam is the main heat transfer medium in industrial processes worldwide. Due to its excellent properties, steam is likely to retain its dominant position as a heat transfer medium in the future.
Steam networks are typically large-scale installations in companies that have grown over years. Especially in case of older installations, processes have changed over the course of their operation. Changes in the process technologies used affect the necessary parameters of temperature and steam – as well as throughput. As a result, the original design conditions may have changed and the installed steam network may no longer be suitable for the requirements. Essential components are installed in the steam network, which have a strong influence on the efficiency of the steam network. At the same time, the training of skilled personnel is inadequate. Steam systems and the correct design and proper operation play only a subordinate role in both academic and craft training. In this way, existing problems
cannot be identified, and necessary adjustments are not implemented.
For the smooth and energy efficient operation of steam networks, this means that potentials for energy savings are often not recognized and operating costs are unnecessarily high due to losses or incorrect design.
As a manufacturer of steam valves with more than 90 years’ experience, MIYAWAKI offers support on this matter. Starting with our steam system audits, we analyze your steam network and show paths for improvement.
The Steam System Audit is a systematic analysis approach, based on a measurement and evaluation of the steam traps and extended by various aspects to optimize the installation. Based on the installed valves, the constructive implementation, the execution and timeliness of the technical/ technological project planning and the project planning in comparison to the current process parameters are examined.
In the first stage, a discussion of the customer’s priorities takes place. In a joint inspection of the facilities and a subsequent discussion, the further procedure, the budget and the focal points of the subsequent audit are discussed.
The audit is carried out by MIYAWAKI personnel. The accompanying report lists the identified deficiencies and provides detailed recommendations for action. The report will be presented at a joint meeting and further focal points will be discussed.
Identified potentials are detailed during the optimization phase by the MIYAWAKI Engineering Team. Project outlines are developed by MIYAWAKI and, if required, also elaborated up to the detailed project planning.
MIYAWAKI offers various forms of support during the implementation. Depending on the customer’s wishes, we are available to advise or take over the entire project management.
