Design of a shell and tube heat exchanger

TL;DR

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?
