Heat transfer coefficient of graphite evaporator
Thread Content
There is a set of equipment for the evaporation and concentration of dilute sulfuric acid, and I would like to ask what the heat transfer coefficient of the graphite evaporator can be
Between 200 and 20,000 W/(㎡. ℃) between. :lol
Bro, your range is way too wide. Is there anything like experience points? :)

Otherwise, scientific design involves specific calculations of heat transfer coefficients, rather than so-called “experience”! For your heat exchanger, the value of K adopted by \"the experienced old man\" is usually 600–800, while for scientifically designed and calculated heat exchangers, K can range from 1500 to 2000. That’s several times less! If you are bidding based on your skills rather than connections, a \"veteran with experience\" usually sets a bid amount of 600-800; in that case it’s impossible for you to win the bid, since your heat exchangers are several times better than those of others.
