Hot Water Radiator for Waste Heat Recovery in a plant

AI Thread Summary
The discussion focuses on a waste heat recovery project involving two ovens in a plant, where heat from one oven at 270°C is intended to be transferred to another oven requiring 200°C. The proposed method involves using water as a heat transfer medium, functioning similarly to a radiator. A key challenge is that water boils at 100°C, which could lead to steam formation and issues with condensates, potentially hindering heat recovery efficiency. The user seeks suggestions on how to effectively manage this heat transfer without encountering boiling issues. The conversation highlights the complexities of designing effective waste heat recovery systems in industrial settings.

Hello, I'm new to this forum and I have a very important question about engineering design.

I am currently working on my final project in my undergraduate study. The project that I am doing is about waste heat recovery design. My case study is a plant with a couple of ovens. The plan is to use the waste heat from one oven to be used in the other oven.
My professor suggested to take the heat from inside the oven and transfer it to the other oven. The heat will be transferred via water and it is supposes to work like radiator.
The temperature of the oven where the heat will be recovered is 270 C and the other oven needs to be at 200 C.

The problem is, the plant needs to recover as much heat as possible, but water boils at 100 C. If the water turns into steam, there will be problem with condensates.

Any suggestion regarding to this?

Thanks!

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
