The relationship between increased heat transfer capacity of the heat exchanger and production load
Thread Content
Experts, is there any formula for determining the impact of an increased heat transfer capacity of a heat exchanger on the load of the production facility? For example, if the heat transfer capacity increases by 3%, does the load of the facility increase by 3% as well? Are there any calculations for this?
1. I’m just a casual fan, not an expert. 2. Basically, to increase the heat exchange capacity, more heat sources need to be used for feeding, but the increase is limited (due to inherent constraints and design of the equipment). To achieve a significant improvement, the heat exchanger itself must be modified (such as by increasing the number or length of the tubes). 3. If it’s just a slight change in the operating parameters (such as adjustments to production and sales levels), then the change won’t be excessive. Heat exchangers are designed with a margin of safety to handle such variations. ---------------------------------------------------------------------- If you really want to understand the relevant details, the simplest way is to use proportions... there will be some errors, but they won’t be very noticeable. The above is for your reference
During use, heat exchangers suffer from scaling and biological sludge, which leads to a decrease in heat transfer efficiency and thus affects production.
It depends on what kind of device it is; if it’s a distillation tower or something similar that involves phase changes and gas-liquid reflux ratios, then an impact of 3% is likely not significant. It’s likely difficult to come up with an accurate calculation formula for this, as the heat of vaporization or condensation varies among different substances. Additionally, regarding the scaling in the pipelines you mentioned, as well as the sludge, it is recommended to treat the water system with chemicals. The above opinions are for reference only; discussions are welcome
An increase in heat exchange definitely has benefits, but there is no specific quantification for them
