Understanding Ethanol Heater Design (10th May 2010)

  
10th May 2010
Mr Desmond Lim's office, Innovillage

Attendee:

• Mr Desmond Lim
• Tan Kian How
• Marcus Tan
• Brenda Chen

Tasks Done:

 

     1. Discussion on ethanol heater

          · Maximum Temperature from Ethanol would be 78°C

               · Too high as optimum would be 50°C to 60°C

          · Copper tubes would be half filled with ethanol to allow expansion

Ethanol Heater (Coil):

     2. Ethanol in tubes would expand due to solar energy

     3. Travel upwards into Digestor to transfer heat energy to the waste inside

     4. It would then condense and the cycle is repeated

Tasks To Do:

     1. Find ideal solution which would give off heat at ideal temperature range

     2. Test out to check whether this idea will work 

     3. Research on other self sustainable heaters

Self Sustainable Heater (5th May 2010)

 
5th May 2010
Mr Andrew Kon's Office

Attendee:

• Mr Andrew Kon
• Mr Desmond Lim
• Tan Kian How
• Marcus Tan
• Brenda Chen

Tasks Done:

• Discussion on self sustainable heater which does not requires electricity

• Decided on Ethanol Heater

• Using solar energy to heat up ethanol, allowing it to enter the vapourised form and then channeling that heat energy to the waste inside. 

• Ethanol would then be vapourised and contain heat energy

• Heat energy would then be pass onto the waste inside

• Ethanol would condense back to liquid form and the cycle repeats.

• As ethanol would only vapourise at 78° C, temperature inside would be kept constant.

Tasks To Do:

• Research on more self sustainable heaters that do not require electricity
