Turbo Burn Barrel Generator

[Anonymous No.2701364]

A turbo burn barrel is a primitive wood-powered engine that runs on wood directly. It could be more economical than a gasifier -> piston engine system.

However, it doesn't seem anyone has made an actual generator. People start them with shopvacs. One should be able to use the compressor wheel to suck air in the reverse direction to generate electricity. How would I prevent dust getting into the shopvac blower and ruining it?

You're not using a shopvac blower assembly to do this. The exhaust gas coming out of the turbo would destroy it very quickly. You need a turbine designed to run off exhaust gas. But keep in mind that the power you extract from the exhaust gas comes at the expense of reducing the efficiency of the input turbo. There will be a lot of work involved balancing the input/output sides to get it running well. Probably be easier to instead use this as a firebox for le boiling water, and use the steam output to drive a turbine & generator.

You could make a water jacket for it too then before getting into thw boiler tubes, nothing is going to hold up to red hot Temps like that.

You use the suction from the compressor wheel.

Or filter the exhaust through a water bath, removing the ash and would achieve a higher thermal efficiency than steam alone.

Could just throw some anthracite into a steel pipe

hello backpressure

Yes, a higher pressure with forward flow will result in a more efficient burn.

Only with sufficient exhaust removal. High pressure in an internal combustion engine is more efficient because fuel injectors closely regulate fuel/air ratio and there's practically zero 'dead' volume. The whole volume of air is exchanged between a series of discrete combustion events. Ergo, higher pressure inside that volume is good because it allows more oxygen, therefore more fuel at a fixed fuel/air ratio, therefore more power per rev.
In a wood burning furnace, totally different story. Single continuous combustion event of a set quantity of solid fuel is governed by completely different rules than repeated discrete events with variable quantity of liquid/aerosol fuel.
Closing the damper on a wood stove's chimney increases pressure inside the stove, and also obviously decreases combustion efficiency (more smoke=more incomplete combustion byproducts)

It's just a turbocharger diy jet engine but running on wood gas. It will run on pretty much anything but isn't useful for much besides shits and giggles.

You'd need to:
>disassemble the turbocharger completely
>replace the shaft with a longer one
>modify the housing to fit longer shaft and power out on one end, usually done on exhaust end
>find a efficient way to gear down the output, probably 50:1 gear ratio
>put everything together

O2 partial pressure and temperature are higher, so it actually results in a faster, thus more complete burn.

>Closing the damper on a wood stove's chimney
Nothing to do with the pressure, and everything to do with the fact that the A/F ratio is out of wack.

>>2701621
It's not technically a jet engine, and doesn't run solely on wood gas, but the wood itself.

>You'd need to
No, because the journal bearings are not designed to handle external loading on the shaft.

these things are basically useless
the only point of them is to make cool noises and fire effects

good thing the thumbnail points out that the tank is red hot, otherwise i wouldnt have noticed and just figured the tank was just painted with some red reflective paint or something.

Enlongate the turboshaft to a high speed generator or use a power turbine that is connected to a generator after the first turbine.
>pressure
Most build failed to seal their firebox door.
>more economical than piston
It won't because very low pressure rise from single stage of compressor and constant pressure combustion are not efficient.

Maybe for a final product, not practical for prototyping.
>Most build failed to seal their firebox door
Could be fixed with a nozzle and proper placement of the "door".
>constant pressure combustion are not efficient.
Not efficient for gas. Still more efficient for solids or oil than gasification.

Could use one of these to dispose of a body right quick and thoroughly.
