Steam Engine Planning
Nick Raaum was the project manager. Our present concept is to use a single acting cylinder made from steam piping, using an electronically-controlled valve, and a position sensor that tells when the valve should open and close.
- Use stock pipe section for replicability
- Welded ends
- Flywheel and pulley is used
- About 150 rpm
- Use stock piston seals
- Machining boils down to lathing piston seal grooves
- Connecting rod threaded into piston, uses two nuts
- Use flywheel and linkage
- Use a condenser - flat plate heat exchanger
On 12.6.08, Nick and Marcin had a strategy session in which we decided:
- Pursue a simple, single-acting, steam engine with electronically controlled valve
- Pursue stock pipe sections to eliminate casting requirements?
- First plan of action:
- Design drawings
- Materials and corrosion issues
- Asco valve - 8 hz, 150 PSIg operating pressure solenoid steam valve - $100 new; one required
- Programmable Logic Controller - Arduino board?
- Position sensor - an optical sensor, photoelectric eye?
- A56 Schedule 80 half inch piping, carbon steel
