Hi Group, I thought I'd put a group of trivia questions, in one email.
Gas Flare - In terms of a small digester, can anyone describe or point to plans for self-assembling a gas flare? I assume it would be a type of pressure valve with an activation for a battery operated igniter, so that if the gas collection bag became too full it would relieve pressure by burning off excess? And any comments or advice on flares in general, or how it might apply to a bladder tank style containment would be great.
Check Valves - I assume a gas check valve would go between the gas containment and the generator engine, also between a utility like the above mentioned flare, .... where else in a small digester system should a check valve be located. I know with the solar water heating for tanks, we just completed ... in terms of a water valve, a "swing check valve" was required because our solar water heating is a closed loop with next to nothing in pressure to open a spring loaded valve. What are the various kinds of check valves for gas, and what is best for a small system?
Insulation Blankets - I know quite a few list members are from outside the U.S. so they may not be able to help, but I'm looking for a UV resistant insulation blanket, black on top and reflective on bottom to cover bladder tanks in winter. These tanks actually have a low profile "greenhouse" shell over them, so the ambient greenhouse temps can be as high as 65C. The blanket would need to be 5 x 9 meters.
Any suggestions for sources to buy? Thanks! Steven -- Steven Bolgiano Executive Director Planet Foundation Ltd.
