SilverFire Hunter Chimney Cookstove
The SilverFire® Hunter, is a lightweight, portable natural draft chimney stove designed for both indoor & outdoor use! The Hunter is a top lit updraft gasifier (TLUD), powered by twigs, yard scrub, or any flammable biomass (why buy fuel?). TLUD stoves utilize a batch-fed combustion chamber that's simple to operate. Just top light it like a candle, no continuous feeding required. Vent the chimney outdoors to eliminate all household emissions. Insert vertical positioned fuel into the combustion chamber; next, place a little tinder on top and light! To fine tune your flame adjust the ventilation door at the bottom of the stove. That’s all there is to it! The portable SilverFire® Hunter model opens up a new frontier in biomass clean cookstoves. You now have the capacity to eliminate all household emissions!
SilverFire® Hunter purchase includes four chimney sections and elbow (as shown in picture). Chimney sections collapse on themselves and fit inside combustion chamber for storage.
The Hunter is easy to light, easily adjusted, lightweight, and cooks very rapidly. Thin tight packed fuel produces a very rapid boil. It has the ability to boil 2 gallons of water faster than the largest burner on your gas or electric cooktop. In the event you want to slow the cooking process down (e.g. slow cooking with cast iron) add thicker, dense fuel into the combustion chamber. Dense material takes longer to burn, ideal for slow cooking. Combustion in the Hunter produces very little smoke or soot, if using dry fuel. The beauty of the Hunter is that the first 20 minutes to half hour of cooking is high fire power (boiling operations, browning meat, etc...), then for the next two hours a wonderful diminishing, simmering heat is present (low fire power cooking). The stove is dialed in for maximum cooking performance. At any time, you can also just add more fuel and primary air to stoke the stove back up to high fire power cooking too! Just add fuel and open the ventilation door a couple of fingers to add primary air is all that is required. This stove is very intuitive and straight forward to operate. At the end of cooking, invert the stove to dump out the small amount of fine ash residue from the bottom of the chamber. The Chimney is divided into 4 small sections to accommodate handling this lightweight, easy to mange stove (14 lbs). It is approximately half the weight of most rocket stoves on the market, due to the quality lightweight insulation, stainless steel construction, compared to other manufacturers using mild steel and cheap clay for insulation.
TLUD technology has been around for over 100 years. Primary air passes through your fuel as it combusts in the combustion chamber and becomes carbon monoxide gas. The carbon monoxide gas is then burned and mixed with the preheated secondary air, above the fire. The secondary air combustion appearance is like a gas stove and is know as a Chinese burner. The end result of your biomass fuel is to produce minimal amounts of ash, soot, and bio-char, which is required to be removed from the stove after cooking for maximum stove performance.
Best of all, unlike a rocket stove, the Hunter does not require hands-on side feeding the stove, or monitoring while cooking. This means you ares free to prepare other dishes or culinary tasks. The Hunter may also be used indoors if venting all emissions outdoors through the chimney. The 3” chimney consists of an elbow piece that inserts into the back of the stove, and four individual stacking sections. Each chimney section is numbered. Most hardware stores carry standard off the shelf 3” chimney pipe & elbows to configure your specific installation requirements. Double walled, insulated chimney pipe not required. Refer to chimney installation recommendations for specific tent stove application. Keep hot chimney away from nylon or other low melting point fabrics.
Special Note: All wood & biomass stoves create soot on the bottom of cookware. It is important to clean the bottom of your pots or, after time, the buildup of soot can impede heat transfer into the pot. There are many industrial cleaners such as Krud Kutter that are effective removing soot from the bottom of cookware with a paper towel, prior to washing. Tough soot buildup may also require a scouring pad and cleaner before washing cookware. Porcelain over steel and stainless cookware is easier to clean than cast iron, regular steel and aluminum cookware. Cast iron cookware dissipates heat effectively, though and the absorption of iron into the food is a benefit to those with low iron blood levels
