The electric candles with their hands: 10% of the capacity of electric heater of 500 W! Bashny.Net

Simple natural materials in one form or another continue his "life and work" as components of modern trains. Thus, the ordinary clay has gone from a free and open source raw material for the construction of the first houses to nano-component composition insulation coating (liquid ceramic insulation). Raw it daubed the walls for insulation, then began to be formed and fired — turned kitchenware and bricks.

With the development of steelmaking clay learned to distend so — called concrete block, and an entire section of science — "the Use of expanded ceramic materials". In the end, it was formed into balls with a diameter of 0.02 mm with a technical vacuum inside. And everywhere clay was in demand due to its main properties: in the annealed form (ceramics), it effectively stores heat. It proves once again that all that man needs for life, already invented by nature.

Is it possible to distribute the heat from the fire ofAnother property of ceramics derived from the heat capacity — the ability to distribute heat evenly throughout the volume (except for the point heating). In other words, if we take something ceramic (e.g. brick) and put it on something hot (e.g. gas burner), then the following will happen:

• the bricks will absorb (recycle) the heat of the burner flame;
• the temperature is evenly distributed throughout the volume of the brick and come to his faces;
• on the surfaces of the brick will be the heat exchange with the ambient air;
• in the end, the heat transfer area increases with the square of the flame to the area of all surfaces of the brick;
• the temperature will decrease inversely proportional to the surface area (the larger the area, the lower the temperature).

Ingenious reader, of course, understood that the above described principle of operation of the Russian stove. Our task is to create the same effective device, but on the base of the candle.

How does the "eternal" heaterDespite its small size, the flame of a candle has the usual combustion 100 °C. the room Temperature should be approximately +24 °C. the Difference is 76 °C. Where does it go?

When burning ordinary candles, the following occurs:

• preheated combustion air rises to the ceiling;
• under the ceiling it mixes with the top layer.

Because of the large difference in temperature (76 degrees) of the surrounding air does not have time to mix with the exhaust gases of combustion, and they both rise to the ceiling. Formed like a column of hot air which dissipated above. This heat we dispose with the "trap" of ceramic domes.

 





Of the heating deviceso that to build a "miracle micro-oven" we will need:

• flame
• fired clay (ceramics)
• metal

Applications of ceramics are limited only by the imagination of the engineer. In this case we are only interested in public cheap materials, particularly, utensils. No wonder in the old days was used in a furnace that is clay pots — they hold heat for a long time. The range of ceramic products for household purposes in our day is huge, but we will focus on the ordinary flower pots. Unattractive in appearance, they will help us to solve the auxiliary heating.

The second component of the heater is the heat source. The first thing that comes to mind for indoor use, this is a common candle. Of course, there are a variety of types of gas and kerosene burners, but the cheapness and availability to us in the first place. In addition, the candle has no expiration date and can be stored in the cold.

The third component is the record for thermal conductivity and lowest heat capacity metal. His ability to quickly heat up and give off heat (low heat capacity) will be an advantage when creating a heat lamp.

Collect heat lamp with your handsThat you will need:

Ceramic pots (flower) trapezoidal with an outer diameter of the bottom of 50, 100 and 150 mm-1 PCs. With a smaller pot must be below large about 25 mm Stud with a diameter of 6-12 mm. It must pass through the holes of each pot. If necessary, holes are drilled to the desired diameter drill bit on tile. Washers under the pin with an outer diameter equal to the inner diameter of the bottom of the smallest pot — 20 Nut in 7-8 pieces. Frame, suspension, or the stand of arbitrary shape, described below meet the technical requirements (conditions). On request — fireplace sealant or non-flammable (paronitovye) strip.

 

Operation procedure1. Install the pin in the hole of the largest pot and screwed the nut on the outside.

2. Put on the pin inside the pot a few goals, if necessary, fix the nuts.

3. Set a medium pot on the stud.

 

 

Attention! Outer face of the smaller pots should be placed inside the large dome at a depth of 20-25 mm.

4. Fix washers and nuts medium pot.

5. Place and fix the small pot.

 

 

6. The faces of all three domes have to go inside the steps of 20-25 mm. Adjust the planting depth by adding washers and nuts.

7. If the distance from one bottom to another significantly large, fill it with washers vrazbezhku — this will give greater thermal conductivity of the rod.

8. Set design over the candle so that the terminal pins located directly above the flame at a height of 30-50 mm.

 





9. Further adjustment is made empirically based on observations.

The use of gaskets and sealant. Praising ceramics, we tactfully bypassed the inconvenient drawback — the fragility of (the preakness). Even brick crumbles, falling on concrete, so to speak, and flower pots. Assembling the lamp, you should be very careful to tighten the nuts — it's worth a little win and the wall will burst. There is also the risk of accidentally split during operation or when carrying. Solid metal studs crumbles ceramics and can split. To soften their contact, use non-combustible sealant or gaskets.

What will be the use of "pot" heaterAt first glance, the design is extremely intuitive, but trust is not. Note — do not rush to cut radiators of steam heating — our lamp will be "apprentice", but not "master". The use of such devices in each room will reduce the overall flow temperature of the boiler by a few degrees absolutely free — and this is the result!

Spend a primitive thermal calculation based on publicly available data and logic:

Wax candle weighing 120 grams (diameter 30 mm) contains about 3 MJ of energy. The approximate date of burning such a candle — 20 hours. During this time, she produces about 140 kJ of energy, accounting for about 42.5 watts. Paraffin candles give greater effect to the allocation of thermal energy.

Choosing the most effective candle, we can achieve 50-55 watts of heat energy output, and this is 10% of the capacity of the electric heater 500 watts.

Attention! A fire hazard. Heating element — open flame. The lamp can not be left unattended.

The scope of theBasic design on the basis of "cheap" materials will be a long time with careful handling. The heater does not require any storage conditions, period of operation, preventive maintenance or replacement parts. Simple, like all brilliant, it would become a mainstay in the forest the night or during a power failure, and in extreme conditions.

In places where there is no electricity, tents, dugouts, shelters, car caught in a Blizzard. In places where there is electricity: small but nice savings on costs for heating. If you collect thoughtful frame, then over the candle, you can hang a small container (pot, Cup) and warm water. Here's a simple and reliable assistant turned. It will not only warm spot in your interior, but also an interesting decoration. published
