Wood - and coal fired vertical boiler

<< < (4/4)

Paddlemex:

Thanks for the explanation Thomas. I looked up Steeple Engine in Google and found plenty of help to understand the mechanism.

Nice idea to use a generator for the "warm summer evenings". Somewhere I saw an article where a guy modified a standard DC motor to look like an old generator. If I can find it again I'll let you know.

Today I hat the first steam up of boiler with engine. I don`t fire with anthracite coal but with kindling and wood pellets. As long as there is no pressure, one must give attention, that the fire don`t goes out. As soon there was a pressure of 1,5 bar, I started the engine. With the draught of the exhaust steam it was no problem to reach 3 bar in short time, engine was runnig well. There is still no feed pump, but the engine could run 45 minutes, until I stopped to avoide scarcity of water. Minimum pressure for running engine this time was 0,5 bar.
With wood pellets it`s very easy to control the fire, after a while of burning the pellets became a glowing pile on the grate. Hotwell was leaking, but this became repaired in the meantime. May be tomorrow I will make an attempt with anthracite coal.

The steam plant with water barrel and feed pump now is finished and working well. I`m looking now for a generator for electric light. Steam pressure raised with draught of exhaust steam up to 4 bar. It`s best to fire with kinding wood in the beginnig and then with wood pellets. I also made a trial with anthazithe coal, but this must have very high temparature to lit. The engine was running 50 minutes, without any use of the feed pump.

There would be also a possibility to use the steam plant for a rather big Úpen model boat a la`"African Queen"
