[Gasification] Gasification or Pyrolysis + Absorption Chiller for Fruit

[Oscar Jimenez Cabeza]

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.

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
