Spent a goodly part of today out at the farm playing Energy Hero where we ran our second generation gasifier for about 3 hours. We have the design of the system to a point now that we felt ready to start tracking some temperatures and taking data on the fuel consumed per hour and such.
The goal of our second generation gasifier is primarily to produce reliably high grade Syn-Gas, and then to facilitate the removal of heat for storage as hot water for later use as space heating, in aquaculture, or even for BioDiesel or Ethanol production. Today we tracked surface temps at a variety of points on the unit for over an hour while measuring fuel consumption. The details are in the linked file below, but here is the skinny: we maintained gas temps under 80 F despite stressing the cooling tower with 100F water. Also we now know that the gasifier uses about 10.5#’s of pellets per hour with our current fan. Not bad! This all took place during the January meeting of my Community Supported Energy Club – we even ate hot dogs and chili cooked on syn gas burners! My first carbon negative lunch!
Link to my pretty chart of temp readings with a descriptive blurb:
Unfortunately I do not have any pics of this gasifier on this computer-as soon as I get them transfered I will post them. We also took good video last week, but it is being edited.
