为了实现环保,所以还是多发些太阳能灶制作方面的资料吧,这样可以更好的实现低碳生活。

Funnel solar cooker
Tilt
to achieve self -
Directed at Lycee Fresnel Paris by Professor Michel Francois optical c**truction with his students BTS GEnie Optique Option Instrumentale.

A Study for Development Association of the village Melga (WMD) in Mali ..

This site is intended for all those who want to develop solar energy to help reduce the greenhouse effect, deforestation and timber transportation by women in Africa or simply for the beauty of transforming energy with maximum efficiency so minimal effort.

Makes one meal per day minimum.

Profitability of the oven in 2 years.

See the 2-dimensional furnace (capacity of the pot: 5 liters or 16.5 liters) in the assembly. The photos correspond to the largest oven.

Four upright with door

open to access the pot.



Shooting angle to 20 ° with flash to see the return of light.

Avoid pleats on the mylar is the light that does not happen on the pot. Some are clearly visible here.

Principle

Transform light energy into heat energy.

Collect: Have a sufficient opening 1.8 square meters to capture solar energy and have the power.

Accumulate: By a black pot, this is absorbing energy so that it spreads inside the container.

Create a greenhouse effect: Water vapor is one of the best greenhouse gas emissi**. So you need a lid to the pot. The glass can follow cooking.

Produce the pressure: The temperature depends on pressure. In the case of a pot with a lid, the pressure increases very low system performance.

No problem of sealing such as in the various systems primarily using the greenhouse effect. A pressure cooker may further increase performance.

Performance, size and cost

- 1400 Watts: Opening area perpendicular to light rays (orientation all 3 / 4 h is sufficient).

- Independent of outside temperature therefore be used in any latitude, but depend on a blue sky.

- Air temperature in the oven: 200 ° 0:30

- Water temperature (For 1.5 liter) in the oven: 95 ° 1:15

- The walls of the oven remain at room temperature

- Oven Capacity (Pot) 16.5 liters. Blackened stainless steel pot over a wood fire: diameter 280 mm, height: 380 mm.

- Funnel : 1.5 m high, diagonal of the octagon 1.7 m. Base opening: 500 x 300mm

- Little glare for the cook, among other things (unlike the dishes): the opening angle was calculated so that the light rays converge in a "focal volume" where the pot. The panel on the floor of the light returns to the pot and a little outside.

- Easy assembly

- Price: 400

Axle lift with these 2 battens + Presentation of the pot.

- The crossover of two laths (wood if you like)

causes a thickening makes the pot unstable.

We must therefore add porti** of the lower slats

to remove this problem.



- The axis elevates the pot to recover

as the light energy from below.

- The two strips have been machined to remove here

the gap height of 2 lattes.

- The previous solution is less expensive.



- The brackets to the 3 ends of the slats

the pot to avoid falling.

- The 4th n'exite not for easy removal of the dish.

The upper part of the pot is oven.



That - it has holes to allow

move water vapor between the two récipiants.



The upper part can serve couscous

or bread oven.



Positioning of the funnel: Failover and orientation so that the axis of the funnel is directed toward the sun.

And you keep the same power throughout the cooking.

- Mounted in the bracket

panel opposite the door.

Enter the desired nail into the hole of the bracket.



The spike topped headless nails every 100 mm

will help tip the funnel according to the

height of the sun in the sky. The shadow of the stake

must remain in the middle of the panel to guide the funnel.

Funnel oriented and tilted for maximum power.

Guidance can also be done by the shadow cast on the ground.

The edges of the shadows remain parallel to the panel on the floor.

Do not take white melamine panels as in the photo,

outside the furnace eventually be dazzling.



The shadow on the white disk shows

bad Bascuas of the funnel.

The shadow on the white disk shows

Bascuas good of the funnel.



Almost vertical position

the funnel, with the nylon

sardine tries tipping rule

in the other direction.

The blocking rule the raised position

of the funnel.



Using a Mylar skirt to increase the reflection on the pot

+ Nylon reinforcement to stabilize and stiffen the assembly.

Place a removable mylar skirt around

the opening, facing the door and held

by strips of double sided tape
 楼主| 发表于 2010-11-3 09:56:22 | 显示全部楼层


Nylon line on each side of

funnel to avoid him

falling due to wind or

when switching from the funnel.



Auban to stiffen the funnel.

Doing very useful to access the dish without changing

orientation and the tilt of the funnel.

Mounted and positioned with the black pot.
Use oven mitts to remove the dish from the oven.

Mounting
- Cut out triangular porti** staggered so as not to have a loss.
- Place the double sided tape on the rear panel. Back panel. Soft mylar reasonably so as not to fold the flap and the adhesive on the back.
- Size of panels:
For a cauldron of 16.5 liters, take the following dimensi**:
Triangular parts: 4 panels 0.8 m wide at the top, 5 cm wide at the bottom (do not keep the tip of the triangle) and 1.5 m high
Rectangular parts: 1 x 0.3 mx 1.5 m, 1 x 0.3 mx 0.3 m, 1 x 0.3 mx 1.20 m, 2 x 0.5 mx 1.5 m, 2 x 0 , 5 mx 0.7 m (the 2nd to be double thickness for the Mylar does not tear during the rotation of the furnace on the base plate).
For a 5-liter cooking pot and 25cm diameter (take a couscousier black), take the following dimensi** (the door disappears):
Triangular parts: 4 panels of 0.53 m wide at the top, 5 cm wide at the bottom (do not keep the tip of the triangle) and 1 m in height
Rectangular parts: 1 x 0.3 mx 1 m, 1 x 0.3 mx 1 m, 2 x 0.5 mx 1 m, 2 x 0.5 mx 0.7 m (the 2nd to be double thickness for the Mylar does not tear during the rotation of the furnace on the base plate).
Fixing wooden panels through open squares at 135 °
