Please help me how to select and calculate this flue gas heat exchanger.
Thread Content
For example, I have a customer who is given a parameter of flue gas heat exchange and hot water into steam. Let me briefly explain the flue gas parameters as shown in the figure. The customer needs to convert 95°C hot water into 95°C steam, and the steam-producing side is under negative pressure. The steam production requirement is 2.7 tons/hour. I don’t know how to select and design this heat exchanger. I would be very grateful if someone could help me with the design and selection.
It is used in multi-effect power plants. This heat exchanger costs around 3 million. It is best to use 316L or QN1906
Is it similar to a low-temperature boiler?
It has nothing to do with the boiler, it just produces low-temperature heat source for the multi-effect evaporator, because the desulfurization liquid evaporation system of the power plant consumes too much energy.
Hello, have you done similar projects? Can you add WeChat 13921272663?
You are equivalent to a waste heat vacuum phase change boiler! It’s quite difficult!
Who says it’s not? Mainly because there are only a few units making this kind of equipment across the country and I don’t know how to design it, so I asked the big brother on the forum for help.
Is 118 degrees before the heat exchanger or after the heat exchanger?
Are the flue gas conditions like this? If you need further communication, you can contact us by phone.
95℃ steam? Saturated steam? If the negative pressure is saturated, what about the -0.015MPa heat exchanger.
