Dear Tom,
I have always been interested in generating cold by using producer gas. I
think it has been an issue which has unfortunately deserved little
attention, when compared to power and heat production.
In order to answer your question, I am sending my preliminary estimates on
the practical refrigeration capacity you are asking for.
1. Assuming 2.5 tpd of biomass to be gasified, it should deliver
roughly 240 m3/h of producer gas.
2. Considering a COP value of 0.6 for the chiller.
3. LHV of the gas of 5000 kJ/m3.
My modest estimates of the refrigeration capacity should be around 200 kW.
I hope those figures could be of help to you.
Kindest regards.
Oscar.

Fruit
In the tropics there are needs for making char and cooling fruit. Has anyone
coupled a small pyrolyzer or gasifier up with a boiler and an absorption
chiller? What sizes and capacities make sense? We're looking at a fuel input
of 2-3 tpd. How much char can I make and what practical refrigeration
capacity can I generate? I am assuming that the chiller can get down to
about 36 F (2 C). The cooler the better.
Thanks
Tom
