It can be designed in either plate or tube format; those who need it can leave a message in the post. Go to Haichuan every 2 days. We can help with the design and selection for anything that can be designed. Format: Company: Unit: Hot side: Cold side: Requirement description:
Various air preheaters, flue gas heat exchangers
I’d like to ask an expert: the coil has a pitch of 2, with a spiral diameter of around 400. Inside the container is hot water, while inside the coil is wastewater; see the picture for more details
The sewage fouling factor is 0.00035; that hot water is just regular hot water
Can the dirt coefficient be expressed as 0.00035 inside the pipe and 0.0002 outside the pipe?
Could the expert explain how to calculate the heat transfer coefficient outside the pipe?
