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.

TL;DR Summary
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?

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
