Syngas Stove, the next generation in gas stoves

 

Introduction

 The Little Wolf eStove is a two-phase Syngas and charcoal producing biomass portable smokeless stove.

 

Versatility and practicality in providing cooking at any remote setting is now here, from base-camp to beach, and everywhere in between. This is your environmentally responsible solution in portable stoves. It is the ideal survivalist and emergency preparedness stove.

 

Step-by-Step

 

1)     Place the stove on level ground, shelter from wind and away from combustible material. On the beach, make sure you never place it directly on the sand as this will suck sand into the fan. Put it on a flat metal disk, rock or wood.

 

2)     Place fuel in burner, start with half load of pellets or 1 to 2 inch dry sticks. Do not exceed one-half inch below the row of secondary air holes. There has to be room for gas and air to mix. Fire is started from the top.

 







Fuel

 

You can burn just about any dry solid fuel as long as it has sufficient heat content. This would include pellets, chips and sticks, as shown below, which will first produce a Syngas for cooking and charcoal for barbecue as a product of the gas conversion process.

 

 

You can try any other fuel you wish, but to create smokeless fire it must be dry, as wet fuel consumes too much heat, and syngas production consumes some heat, but produces lots of heat. Placing longer sticks vertically will work if they are dry, but you risk uneven burning and sometimes smoke.

 

History

 

The concept of producing cooking gas from biomass was pioneered for the common folk in Asia and Africa, to reduce the tragedy of deforestation and ambient smoke in living quarters. Instead of armloads of wood, a hand-full or two will do. The technology is now available for the Western world where we can benefit by recycling Pine Beetle killed trees in pellet form, waste wood, dried chips that are destined for pulp mills and almost any solid fuel that has enough heat energy to produce the Syngas. Dung is used widely in many African and Asian countries. By experimentation, you will find what works for you. Make it your project and contribution to the environment.



FAQ

 

Does the Little Wolf stove produce smoke?

 

Ans: If the fuel is wet or not placed evenly, at the end of the burn, some fuel has gone into the charcoal phase, while a few that have been left behind are still producing gases. In these cases smoke may be seen for a minute or two. Wet wood may smoke until it has dried enough to produce gas. It may have to be relit several times, avoid.

 

May I use other power sources?

 

Ans: Yes, as long as the voltage is between

9 and 12 Volts. You may plug it into your car, portable jump-start power and other 12 Volt sources as long as the polarity is correct. Do not overcharge, remove from

charge after several hours. Voltage should be just under 13 volts.

 

How do I maintain the battery?

 

Ans: Lead-Acid batteries must be kept fully charged. Use the charger provided, or you can purchase a Solar charger/maintainer to trickle charge the battery, but avoid leaving it charging in strong sunlight for more than a few days.

Switches to Barbecue, uses self-generated charcoal

 

 

3)     You can use paper starter, but it tends to be too light and fly away. Better are wood chips or shavings, which are available in any pet store. Birch bark is good and starter fluid can be used.

4)     Once the top of the fuel is lit, you may plug in the battery to start the fan. This supplies the correct ratio of primary and secondary air to create and burn your gas.

5)     You may add fuel at any time, but do it gradually as the fire may go out and you will have to relight it with a wad of paper. Do not relight with liquid starter. Once the stove is lit, the flame will be hot. If you prefer a lower heat, wait until the flames begin to subside and control the heat by adding the desired amount of fuel just like you would in a regular charcoal barbecue. If your stove came with a voltage control, it can be used to lower the heat,

 

6)     Remember: there are two phases

to the burn: 1) cooking with gas, and 2) barbecuing with charcoal you have produced. Use the high X grate for cooking and the grill grate for barbecuing. Enjoy!






Warning

 

Take extra care to prevent burns. Any part of the stove could potentially be hot enough to burn the skin, so be careful. Keep children away and do not permit playing around this stove. Never touch any grate with your bare hands. Use tongs or pliers to change grates.

 

Note: For outdoors use only. One of the fuel gases in this Syngas is carbon monoxide, which burns to form carbon dioxide. Therefore, to be safe, do not use indoors as there is always some CO which could be dangerous. To avoid flame-outs, use the barbecue grill grate only after flames have gone out.

 

Maintenance

 

Use flat black stove paint to keep your stove looking new. Empty the ash regularly by removing and inverting the inner burner unit. Removing the 2 safety bolts allows you to change the fire grate. The burner unit is serviceable too; keep it clean.

 

Normal Charging

Solar Charging

 

You may also maintain or recharge the battery with a ColemanTM battery charger. This will be great for camping and you can recharge your electronics with it. Recharging time depends on sunlight. If the battery has been left to discharge, you may have to trickle charge it with this method.

Simple Guidelines for Lead-Acid batteries

  • Always store lead-acid in a charged condition. Never allow the open cell voltage to drop much below 2.10V. Apply a topping charge every six months or when recommended.
  • Avoid repeated deep discharges. Charge more often. Use a larger battery to reduce the depth of discharge.
  • Prevent sulfation and grid corrosion by choosing the correct charge and float voltages. If possible, allow a fully saturated charge of 14 hours.
  • To reverse sulfation, raise the charge voltage above 2.40V/cell for a few hours.
  • Avoid operating lead-acid at elevated ambient temperatures.
