  1. Vcella is a well known manufacturer of assay ovens.

     

    Do the math;

     

    The largest Kiln/oven made by Vcella is the Model 200. It is a 25.68 Kilowatt oven.

     

    Conversion of BTU's  to Kilowatt-hours;

     

    1 Million BTU = 293 Kilowatt-hours.

     

    That's equivalent to running MORE THAN TEN of the largest ovens available for one hour.

     

    Engineering requires an understanding of mathematics.

     

    Smelting is obviously an option for the small miner.

  2. Chris, FYI,

     

    68 pounds of Red Brass weighs the same as 68 pounds of gold. If it will hold 68 pounds of Red Brass - then it will hold 68 pounds of gold.

     

    That's approximately 991.7 troy ounces of gold. Note: it's also approximately 991.7 troy ounces of Red Brass.

  3. Waste oil;

     

    A byproduct of mining is waste oil, contaminated fuel oil and unleaded fuel.

     

    Every time I prepare for a fuel delivery... I dump empty 55 gallon barrels into a 5 gallon bucket and funnel the "P" into a waste barrel. This separates sediments, insects, and other forms of fuel contamination from clean incoming fuel.

     

    The "P" barrel provides a perpetual source of heating oil for a simple 1/4 cut-off 55 gallon barrel.

     

    The stove is simple, cheap, portable, easy to clean. Oil and grease rags are usually discarded and burned with trash. I separate burnable trash and burn it in the Hobo burner.

     

    Using ote's suggestion of "mass heat storage" is an excellent idea. Most old mines have cast iron relics of all sorts and descriptions that can be heated by the heater and will store heat and provide slow release for many hours.

  4. Hobo Heater;

     

    Multi-fuel - oil burners are the heater of choice. Issues that can be problems are soot build up and level of burn needed to prevent soot build up.

     

    A low level burn will not produce sufficient heat to force soot up a chimney.

     

    Fuel is readily available, easy to transport and easy to store in remote locations.

     

    At my remote campsite 2 miles from the cabin at Ophir, I use a simple "Hobo heater". :)

     

    A Hobo heater can be anything from a #2 coffee can to a 55 gallon barrel with the end cut off. Works on the same principle as a candle. You have discarded grease rags immersed in a small amount of oil. The rags work like a wick. If wood is added, the charcoal will provide similar wick action. The purpose of the wick is to produce a slow burn and not heat the oil to combustion - the wick burns slow and almost indefinitely. 

     

    This option requires adequate ventilation. Having lived in Fairbanks, I know mid-winter temperatures actually suck the heat out the door when you open it. For fall temperatures to late fall, with ventillation, the Hobo heater works great!
