Paal Wendelobo, January 2010

Attached you will find a prospect of the new TLUD called MUS (multi use stove).

MUS The multi-use stove.

Production: Simple to produce

  • By hand by local tinsmith or craftsmen
  • By mechanical workshops.
  • By mass-production

Practical use

  • As a two blaze household cooking stove
  • Easy to move the pan for simmering
  • As a energy unit for huge pan cooking at institutional kitchen.( more units together)
  • As a room and water-heater
  • For grilling and camping
  • Rescue stove and refugee camps

Fuel (Simple adjustment to type of fuel, less dense fuel need a bigger volume)

  • Pellets. 10cm x 14 x 15-50 cm hwl
  • Chopped wood. (size depend of type)
  • Woodchips. (size depend of type)
  • Briquettes (size depend of type)
  • Wood-sticks (size depend of type)

Advantages

  • Fuel conserving, fuel-consumption easy to adjust to need of energy
  • Possible to refill.
  • The two blazes cooking, makes it easy to make a meal on one filling
  • Same unit for household and institutional cooking
  • Smokeless and clean burning. No soot (depend a bit on type of fuel)
  • The pot will come closer to the glowing charcoal for longer simmering
  • Easy to empty the ashes and leftover char

The multi-stove is not jet official tested for emission, soot and tar, but looks promising.
The stove needs more testing and some design is needed before the final product is ready for production.

It was tested informal by Aprovecho, but we made a mistake by filling both chambers at the same time so too much of the flame went outside the pan and all figures was wrong. The emission test without pan was quite low, almost the same as Peko Pe. The MUS is definitely best with pellets.
