G'day Guy's, About 5 years ago I was researching into using steam so for a bit of fun I made a flash boiler. Well work got in the way and it sat in the corner out of mind ever since. Now as I am back in the creative mode I decided to give it it's first run and see if it actually works. Well after a few minutes water started spewing out so I backed off the water flow, then yea we got steam spewing out and it didn't take long for the condensation to show on the shed. Now the pic isnt the greatest and I will take another pic once I got it plumbed up.  The unit sits in an angle iron frame and I used some ali form an old solar hot water panel to encase it. Today I managed to ram 4 off insulation panels in so when operating the unit will be to the touch and not burn the unsuspecting. Basically a 4" copper pipe is used as the housing and I crudely bent some 3/8" pipe for 63 turns using my pipe bender. This was way before I learnt to work with copper and as it's all internal no-one will see it anyway. The next step is work out the input water so it runs at the intentional level and I do need more gas before this project can go any further. The idea is a few years ago I converted an old 5hp B&S motor to stroke by welding an extra cam lobe on the cam shatf and got the enigne running off compressed air so if it runs on air it should run on steam. With my leatherwork steam do come in handy so it will have other uses and it will be interesting to see how long it takes to boil say 40 litres of water. Anyway fun projects on the farm are my go and this yet another one. Cheers Bryan |

There was a steam car that used a flash boiler long ago.. Perhaps you can run your tractor with steam? Steam tractors were all the rage 150 years ago  .Klaus |

Traction engines YUM YUM check out "steam chest" on google. THEN see what a flash boiler can do. Some years ago ( early 70's) I worked at Yubulu. ( now Clive Palmer queensland nickle) I worked in the power station doing instrumentation ( 15 PSI compressed air ). There were four flash boilers that were big enough to hold about twenty boiler makers and their TA's. I have forgotten how much power they produced, but there were four turbines driving four generators at 420 revs. They could supply the plant AND townsville !!!. They were replaced sometime later, but the chimney stack was the largest in the southern hemisphere. The boilers used Diesel. That may be why. The plant only emergency power was a Blackstone heavy oil engine, that started life in some British navy ship. 2 straight eight engines counter rotating driving a common output shaft!!! Sorry lads, just thinking about boilers. OHH and the boilers and associated steam pipes were all welded with low hydrogen LH70 rods. They need be baked in an oven to 130 degrees C before you can use them. THat useless bit of info for Grogster. Joe |

G'day Guy's, Spent this weekend getting the flash boiler finished and I gave it a run today. flash boiler Once I got the water rate set it was working nicely so put the hose in 10 litres of water. The temp was 18C when I put the hose in and about 1/2 an hour later the temp was 63C. Cheers Bryan |
