About Efficiency of Wood Burning Fisher and EPA Stoves




Fisher wood stoves released about 50 – 80 grams of smoke for every kilogram of wood that was burned. By closing steel chimney off and limiting release to only a small hole, 6 inches in diameter, the heat would be retained in the room. It’s very important to underline that the new clean burning Fisher stove released less than 6 grams of smoke on every 1 kilogram of wood that was burned. These new clean burning stoves are known as EPA outdoor wood stoves.

The fire could also be controlled more easily. In addition, these new wood stoves could easily be used for cooling. Fisher wood stoves were made from heavy steel plates ¼’ and 5/16′ thick. The doors were made of cast-iron. Bob Fisher gave the original names for the models of stoves. They were “Papa Bear,” “Momma Bear” and “Baby Bear.” Nowadays the stoves designed by Bob Fisher are manufactured no more. However, they are still sold as vintage goods and have become collectors’ items.
In the mid-1980s the old wood stoves were replaced by clean burning stoves.

As for the design, the design of the Fisher stove was based on observing how heat was lost from a wood burning fireplace. The Fisher wood stoves had a plume-pipe that extended from the top of the steel box structure and released the smoke outside. Older models had steel doors. Newer models had heat resistant glass doors to show the fire within.

Bellows for Wood Burning Stoves and Heaters




There are two types of fireplace bellows in those days.These include the single-acting piston bellows joint and the double-acting.The functions bellows by air in and expel the air in two separate and different movements of the handles.The double-acting piston bellows to allow air to be blown in two strokes of the bellows "handles.It is very important to stress that this brat to be stronger.

They provide more air than the traditional single piston bellows.Fireplace bellows consists of an air chamber and a valve (or nozzle.can) The air chamber is like an accordion design, to grow it and get flexible contract.Fireplace bellows two handles, which concluded when, strength, breathe in the Hall ", drawing air inside for storage.If the handles are pushed down, the air chamber forces the air through the nozzle.Air from the nozzle and onto a small fire or smoldering log to stoke the flames.

The handles are raised again and again and pushed the air is sucked in and pushed, so that for the regular features of the air.The wood burning heaters is a stove, the water-coated according to the following scheme works: the water that the oven is heated and pumped through the pipes, cover to heat the building.Heating is not the only function of the wood stove.To obey the wood stove for hot water in sufficient quantity to meet the needs of an entire house.

Mineral Dolomite and Sedimentology




That said, there may be a higher proportion of one cation than the other, are shown in the general chemical composition of the above chart.The higher the temperature, the greater the leniency to this rule.At higher temperatures, the molecules and the structure of dolomite excited and can expand to accept different amounts of cations.Iron (Fe ² +) can also be for both cations to an extent replaced.Generally Dolomites as a magnesium-iron ratio of at least 4:1 is defined. Sedimentology studies all types of dolomites.

Higher amounts of iron in the solution may appoint another intermediate form called ankerite solid solution, a complete solution with fixed forms dolomite.Occurrence USES Dolomite is a relatively common mineral and is a major component of sedimentary dolomite.Nesse (2000) writes, is that known as dolomite dolomite.

It will be generally formed as a limestone as a result of diagenetic alteration of calcite, but other theories of its origin in the last few centuries have been created.Nesse (2000) claims that increasing the replacement of calcite to dolomite pore space in the original limestone, dolomite beds allow serve as a reservoir rock for oil deposits can.Dolomite can also occur in hypothermal, mesothermal and epithermal veins, nuclear medicine, massive and widespread hydrothermal deposits replacement, carbonatite, marble, lime-silicate gneisses, skarn and associated regional contact and metamorphic rocks of limestone, won dolomite and other carbonate -rich sediments (Nesse, 2000; Chesterman, 1978).

Some places where is dolomite occurrence are known, the Dolomites in northern Italy, under the Abu Dhabi sabkhas, United Arab Emirates, in the ephermeral lakes of the South Australian Coorong Lagoon in the Ontario peninsula between Lakes Erie, Ontario, Huron and the Mississippi Valley.
