What are limiting factors to high temperatures ? Challenge # 1 Cool stove body Cool earth the body of the stove or of the earth robs heat from the fire which lowers combustion temperatures… which decreases efficiency…and increases smoke Solution? Insulate the stove with low mass, heat resistant materials in order to keep the fire as hot as possible Remember mass is the opposite of insulation Effective stove insulators are pumice , vermiculite, and wood ash Dense things such as earth,sand, cement, water and cast iron are poor insulators
Maximizing combustion efficiency Challenge #2 Cool wood which lowers combustion temperatures…which decreases efficiency…And increases smoke Solution? Meter the fuel! Use small sticks whenever possible Maximize the surface area of the wood exposed to coals Heat only the fuel that is burning • Burn the tips of sticks only as they enter the combustion chamber

Maximizing combustion efficiency<br />
Challenge #2<br />
Cool wood<br />
which lowers combustion<br />
temperatures…which<br />
decreases efficiency…<strong>And</strong><br />
increases smoke<br />
Solution?<br />
Meter the fuel!<br />
Use small sticks whenever<br />
possible<br />
Maximize the surface area of the<br />
wood exposed to coals<br />
Heat only the fuel that is burning<br />
• Burn the tips of sticks only as<br />
they enter the combustion<br />
chamber
