[Gasification] Torrified woodchips as a gasifier fuel

This is the website of the "preserved" engine in Australia: http://members.fortunecity.com/freeenergy2000/humphreypump.htm This is only a baby compared to the pumps at chingford which were made of sectionalized Cast iron bolted together, Im not sure if they still exist, they were not in use when I visited them. the 12Ft diameter pump used to lift 100 tons of water,  58 feet in one minute .

Hi GF,
hank sounds like an interesting engine, can you provide any more details? 
re they still in operation?  Got any photos or diagrams?

 I have had the privilege of standing on the 12 ft diameter cylinder head 
 of one of these engines in the pump house.
 These were long stroke engines. the piston was water, the shape of which 
 changed to make the most of the Rankin and carnot cycle. The exhaust gas 
 was less than 95 F.
 The fuel, Anthracite, converted to, producer gas, was practically all used 
 in each power stroke. The equation for the efficiency of this engine did 
 not include the mining or transportation of the anthracite, merely pounds 
 of raw fuel for work performed, there for the inefficiencies of the 
 gasification plant was included.

 Max,
 don´t know tto which reports on pollution created by wvo or svo you refer.
 here was a kind of campaign in german media  some time ago, but the tests
 hey made were in totally unprepared vehicles and much contested.
 o you have any trustworthy analisis/data ?
 would apreciate them.
 anks
 olf

 "Straight veggie oil is much, much more polluting than fossil diesel
 fuel, but biodiesel is a good bit less polluting than fossil diesel."

 If one only looks at comparing the 3 fuels themselves, this is true.
 However if one takes into account the imbedded energy/pollution of each in
 addition to that produced by using the end product then the WVO is far
 less costly both in energy costs and in total pollution produced.  For
 example diesel has to have added the extraction costs, the environmental
 impact costs (such as the Vancouver pipeline rupture), the refining energy
 costs etc.  The biodiesel has to include the energy/pollution in the
 process and process chemicals such as methanol and sodium hydroxide as
 well as disposal of the glycerine etc.  Yes, WVO has imbedded costs for
 processing, transport etc but they are lower as the material is far less
 processed and the costs are shared with the food industry as that was the
 primary use of the WVO.  An example of re-use advantage.  This last
 consideration is not true of diesel and partially true of biodiesel
 depending on the ratio of WVO in the
 BD.  The end use only mindset, which the starting quote embodies, needs to
 be replaced with a total cycle cost mindset.  That is not to say those on
 the list aren't aware these "hidden" costs exist however it is to say that
 the language we choose to use influences the thinking processes both of
 ourselves and those we talk to.  Just because some of the pollution to
 produce the more refined BD doesn't come from our tailpipe, originating
 from the methanol plant or the production of NaOH instead, doesn't mean
 that the pollution doesn't exist and isn't harmful.

 Off the soap box.

 The idea of trapping the waste carbon and using the waste heat from a WVO
 powered diesel using biomass destined for gasification sounds excellent to
 me and is a great example of whole cycle thinking that will truely
 overcome todays challenges in the future.
