AI Thread Summary
Designing a shell and tube heat exchanger for a 100kW rice husk gasifier requires cooling syngas from 300°C to 60°C, utilizing syngas on the tube side and cooling water on the shell side. The discussion revolves around determining the number of heat exchangers needed, with questions about whether one, two, or three units would suffice. Participants are encouraged to share their experiences and methodologies for setting the temperature range for each exchanger. The design must consider efficiency and thermal performance to achieve the desired cooling. Effective design will ensure optimal heat transfer and system reliability.

shell and tube heat exchanger for gasifier cooling system
I need some help with designing a shell and tube heat exchanger for a 100kW rice husk gasifier. The goal is to cool the syngas from 300°C to 60°C, with the syngas on the tube side and cooling water on the shell side. How many shell and tube heat exchangers would be required for this task? Would one be enough, or would I need two or three? Additionally, how should I set the temperature range for each exchanger?

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...
Thread 'What type of toilet do I have?'
I was enrolled in an online plumbing course at Stratford University. My plumbing textbook lists four types of residential toilets: 1# upflush toilets 2# pressure assisted toilets 3# gravity-fed, rim jet toilets and 4# gravity-fed, siphon-jet toilets. I know my toilet is not an upflush toilet because my toilet is not below the sewage line, and my toilet does not have a grinder and a pump next to it to propel waste upwards. I am about 99% sure that my toilet is not a pressure assisted...
After over 25 years of engineering, designing and analyzing bolted joints, I just learned this little fact. According to ASME B1.2, Gages and Gaging for Unified Inch Screw Threads: "The no-go gage should not pass over more than three complete turns when inserted into the internal thread of the product. " 3 turns seems like way to much. I have some really critical nuts that are of standard geometry (5/8"-11 UNC 3B) and have about 4.5 threads when you account for the chamfers on either...
