APPLICATION OBJECTIVES FOR 'CARBON NEGATIVE' COOKING AND WASH

 
- multi-fuel
    - biomass pellets eg. Wood, bamboo, rice husk
    - briquettes eg. Newspaper, biochar
    - environmental biomass eg. Sticks, manure
- multi-quench
    - water
    - soil
- group trekking stove (too heavy for solo trekking)
- car camping, caravans, tiny houses etc.
- expeditions eg. 4WD, trekking base camps

TECH SPECS

- 5"/127mm 304 chimney flue
    - height (210mm)

    - single row primary air slots (10mm from bottom)
    - single row secondary air slots(130mm from bottom)
    - stove weight: 369g + 235g (pot stand)
- large pot stand (cross piece), 2.5mm 304, which is 10mm above the top of a standard 10 piece heat shield so larger/wider cookware can be used 
- 1kg biomass pellets capacity 
- suitable for sticks, vertically stacked 
- bottom pot quench system eg. Scanpan 18cm thick bottomed pot
- can be soil quenched
- suitable for Tatonka 2.5L, Billy 3L, frypan

- 2 litre stainless water bottle for water storage (and cooling) after water pasteurization
- could use by itself (hotter flame) or in combination with the 4" Navigator 'Backup' (cooler flame) for a second stovetop
- can use a 8 or 10 piece heat and wind shield placed around pot

OPERATION

-position the stove in the centre of a thick bottomed pot on a flat surface (if using a water quench) (or flat piece of ground if using a soil quench)

-fill the stove with fuel eg.wood pellets, rice husk pellets, bamboo, sticks etc. up to desired level to a maximum height of 10mm below the secondary air slots

-add a circle of firelighter gel 2cm in from the tube edge (or 3 cotton wool buds soaked in kerosene)

-position the pot stand (cross piece) guided by the 4 notches

-light the stove from the top with a wooden skewer lit at one end (or a BBQ lighter)

-position the cooking accessory eg. 2.5L Tatonka, 3L Zebra billy, stainless fry pan, on top of the cross piece after 2 minutes

-ready to run without adding any additional fuel during the burn

At the end of the burn:

-flame goes out and usually smoke follows

-put on some leather gardening gloves (and keep them on until the water quench or soil quench has been performed)

-remove the cooking accessory

1-Water quench (if enough water is available). Add water from above the top of the stove eg.water bottle or jug, for initial quench of biochar pellets until quench pot water level is above the primary air slots (mind the steam)

-lift the stove vertically eg. 20cm above the quench pot, with billy lifters/pliers/C clamp, and the biochar will fall out the bottom (may need to use a stick to push out the biochar)

-using a stick, stir the biochar into the water and there will then be a complete quench

-empty the quench pot into a bucket eg. a 20L stainless one with mesh top,  then it will be ready for the next burn

OR

2-Soil 'quench'. Next to the stove, dig some soil and make a pile before the burn.

-remove the pot stand (cross piece) with billy lifters/pliers/C clamp

-fill up the air space between the heat and wind shield and stove plus the air space inside the stove, above the biochar, with soil

-Leave for 10 minutes

-lift the stove vertically with billy lifters/pliers/C clamp until all the biochar and soil has fallen out the bottom (may need to use a stick to push out the biochar and soil)

-mix the biochar in with the soil inside the shield space

-remove the heat and wind shield

-add the biochar and soil mix back into the soil hole, next to the stove 

-the climate and microbes will love it!)
