What do you get when you take an Isabella gasifer, add the Gas Station air cooled cyclone, and the air cooled final filter kit? You get a mini gas station! This unit is appropriate for running engines up to about eight horsepower. This is typical of a 4kW generator. Below is a picture of my test rig:
The performance numbers obtained in the flare test run were pretty impressive. The gas coming out of the gasifier was running about 750F(399C) at a flow rate of about 12cfm(340l/min). The air cooled cyclone dropped the gas temperature 400F(!!) to an exit temperature of 350F(177C). The final filter with the heat exchanger modifications then dropped the flow’s temperature to 130F(57C) at the exit!
The engine test actually produced a lower gasifier exit temperature than the flare test. The gas temperature was only 650F out of the gasifier, 250F out of the cyclone, and about 110F from the final filter. That means there is certainly plenty of capacity left for an 8hp generator’s load.
The Mini Gas Station is available for $1200 plus shipping.
