<br><div>Gentlemen,<br><br> Today I took a six mile drive without the fuel-fill hatch dogged down.<br>There is a vast range of adjustment setting for the fuel /air-inlet luft-control.<br>The more the operator screws down on the inlet-valve, the more woodgas is admitted, while at the same time the secondary combustion-air is trimmed.<br>So it ran well with the hatch ajar. <br><br>There is much convecting pyrolysis gas emitted from wood in the fuel bin, as the load increases. It is sort of a pressure that follows nozzle firing-rate.<br>Gas-demand remains below this evolving pressure with respect to ramping up fires with this Imbert; open-top. No smoke comes out, and you are good.<br>Decending grades especially after cresting hills; much smoke issues the fuel bin until the fires cool.<br><br> Jim had wanted discussion on whether fiber stove rope actually seals.<br>On another list those whom replied, decided it does not, and some sealant-slathering discussion ensued. <br>I described how a neoprene O-ring type joint can be bubble-tight.<br>Uses for this joint are: cyclone tail-bin covers, gas-cooler header-access hand-hole covers (shell and tube exchanger),<br>and of course high-cycle joints for fuel-fill hatches.<br><br> Renewable Fuel Systems can produce weld-on combings to match gasketed covers; either leaf-spring loaded or static over-center latches.<br><br><br>Diameters are 8" and 12". <br><br>Andrew Schofield<br>Glrf30 at yahoo dot com<br><br><br></div> </div></body>
