英文要約Title: Grasp and Modeling Examination Concerning Actual Heat Utilization of Steam etc. in Manufacturing Processes/Analysis of Heat Loss by Measuring the Amount of Steam from Boilers when Not under Load (FY2018-FY2019) FY2018 Annual Report

Limiting the use of fossil fuels in factories is essential in achieving decarbonization in the long-term. Due to its ability to accommodate a wide temperature range from low to high temperatures, steam, which has long been used as a heat transfer medium, is being used in a wide variety of factory manufacturing processes. With excellent its 'usability' as a heat transfer medium, steam (i.e. fossil fuel) is still relied on to meet much of the thermal demand at factories. However, actual use of the heat from steam in factory manufacturing processes is not totally clear.
The purpose of this study is to analyze and fully understand the actual situation concerning steam-generated heat by measuring the amount of steam from boilers when not under load, and then considering a heat utilization model for manufacturing processes which can help save energy and reduce carbon emissions.
In fiscal 2018's study, we mainly organized and analyzed past measurement results taken from several factories;
(1) Definition of heat loss and the process for calculating heat balance in a steam system
Heat loss of a steam system was classified into boiler loss, pipe loss, and drain loss. We then standardized the definition of each type of loss, as well as the calculation procedures.
(2) Organizing past measurement data
We carefully checked the actual data measured at several factories based on (1) above, and organized the results as data to be used in the analysis of this survey.
(3) Analysis of multiple sets of measurement data
Using the data organized in (2) above, we analyzed the correlation between piping loss and the factors that influence it. The analysis found that there is essentially a first-order correlation between input heat quantity versus annual pipe loss, as well as pipe length and pipe surface area versus unit time.
(4) Selection of new factories at which to take measurements
For the correlation analysis in (3) above, there was insufficient data on piping―specifically piping length and diameter. This caused results to be highly uneven. Therefore, we will hold fact-finding interviews on piping data details at factories targeted for new measurements, and use this to verify the accuracy of (3).
