How to prepare material balance sheets and energy balance sheets
Thread Content
Experts hired by the Emergency Management Bureau came to the company for an inspection and pointed out that the operation procedures for various positions in the coking plant did not include material balance sheets or energy balance sheets. Could someone please advise on how to prepare these two types of balance sheets? Thank you!
Use Excel and have the chief engineer do it!
Regarding the energy balance sheet, it covers various types of energy purchased, their storage, conversion, and transmission, as well as their use at various end points; waste heat recovery is also taken into account, with statistics on energy consumption, efficiency, and losses after converting these values to standard coal. . . . GBT28751 and 28749 can be used as references. Also, I don’t think the operating procedures have anything to do with this; it should be the energy engineers who are responsible for the statistical analysis.
This balance sheet is usually provided by design institutes during the design process; it would be extremely complicated to calculate it internally within one’s own company.
There are design documents available that include information on material and energy balances; if not, calculate it yourself by defining the scope of the calculation and determining the materials that enter and exit
Does the chief engineer have to handle all this work? The engineer in charge of energy in the production department should have this capability; if not, the head of the production department will do. The chief engineer should be responsible for pushing forward this work or reviewing the final product reports. . .
The original design sheets from the design institute can be used as a template, and the information can be filled in based on actual consumption levels. Moreover, such sheets are extremely useful, as coal chemical industries are high-energy-consuming sectors; everyone is currently seeking to reduce costs by cutting down on consumption. Without actual data on material and energy balances, any talk of saving energy and reducing consumption remains just that – talk alone. Furthermore, such a table isn’t complicated at all; here’s a general idea you can use as a reference: for instance, there should be some way to measure the total input and the total output, right? Is there metering for the total power consumption at the plant level? Is there metering for the actual energy consumption in each workshop? There must be a difference between the two, right? The difference is the energy input loss. . When all these various elements are combined, it constitutes material balance; and when the materials are converted into energy according to standards (standard coal or standard oil), it results in energy balance. If there are better ideas or methods, we can write them down together for everyone to discuss and exchange views on. .
