Session 21. Design and construction of the second stove part one: stove base

Total time:

1 hour

Objectives:

* To design and construct a second, improved cookstove
* To lay out and build the base for the second, improved cookstove

Resources:

* Aprovecho Institute, Helping People in Poor Countries, pp. 111-144
* Evans and Boutette, Lorena Stoves

Materials:

Clay, sand, rubble, water, earthen blocks, bricks, soil cement blocks, rocks, mortar, sifters, shovels, hoes, machetes, trowels

Trainer Notes

The format for building stoves a second time may vary, according to the training program. Depending upon the needs of the participants and the time available in the program, the following options can be exercised:

* The second stove may be completely built anew, beginning with the base construction, including new clay and sand for mixing.

* After removing the clay/sand mass, the second stove may be built from the original base or floor, using the same mix or mixing anew, emphasizing speed, finish and care.

* A second stove may be designed but not built.

At least one of the original stoves should be left for use during the Health and Nutrition sessions.

Procedures:

Step 1. (5 minutes)
Explain the session objectives and review the activities

Step 2. (5 minutes)
Discuss and clarify the second stove construction options.

Trainer Notes

Explain that constructing a second, improved cookstove is an opportunity for independent work and the application of stove principles learned to date.

Explain that the participants may select a stove design appropriate to the country in which they will be serving.

Suggest the following improved charcoal stove designs for those participants who will be going to urban areas or countries in which charcoal use is common:

* The Voltena stove
* The Singer stove
* Sand/clay (Lorena) charcoal stove
* Portable metal charcoal stoves (the improved Tiki, for example)

Participants may also choose to work on improving the designs of existing charcoal stoves. Additional designs (and details on the stoves listed above) can be found in Helping People in Poor Countries.

Mention that since sheetmetal stove pipes may be expensive or unavailable, stove pipes should be built from alternative materials such as Lorena blocks, ferromud, bamboo, clay tiles, etc. (Refer the participants to Lorena Stoves for more information.)

Explain that the work groups building cookstoves with chimneys will be asked to give a presentation on chimneys during the stove tours (see Phase II: Session 22) and should pay special attention to the previously-cited reference.

Step 3. (50 minutes)
Have the participants form their work groups, design their stoves and lay out their stove bases.

Trainer Notes

The procedure here is the same as described in Phase II: Session 10, Part 1.

DESIGN AND CONSTRUCTION OF THE SECOND STOVE PART TWO: STOVE MASS

Total time:

3 hours

Objectives:

* To design and construct a second, improved cookstove
* To build the mass for the second cookstove
* To use stove construction skills

Resources:

* Aprovecho Institute, Helping People in Poor Countries, pp. 111-144
* Evans and Boutette, Lorena Stoves, pp. 50-57 and 66-68

Materials:

Clay, sand, water, sifter, machete, trowels, shovels, hoes

Procedures:

Step 1. (5 minutes)
Review the session objectives and outline the activities.

Step 2. (2 hours, 55 minutes)
Have the participants form construction groups and construct the stove masses.

Trainer Notes

* Details on the construction of the stove mass can be found in Phase II: Session 10, Part 2.
* Encourage the participants to experiment with alternative chimneys. (Refer them to Lorena Stoves)

DESIGN AND CONSTRUCTION OF THE SECOND STOVE PART THREE: EXCAVATION AND FlNISHING

Total time:

2 hours

Objectives:

* To design and construct a second, improved cookstove
* To excavate and finish the cookstove
* To construct an alternative chimney for the cookstove

Resources:

* Aprovecho Institute, Helping People in Poor Countries, pp. 111-144
* Evans and Boutette, Lorena Stoves, pp. 58-69

Materials:

Clay, sand, water, machete, trowels, spoons, shovels, hoes, bamboo, sheetmetal, wood (for dampers, baffles), nails, hammers

Procedures:

Step 1. (5 minutes)
Present the session objectives and outline the activities.

Step 2. (1 hour, 55 minutes)
Have the construction groups excavate and finish their second, improved cookstove.

Trainer Notes

The procedure for the excavation of the stove mass can be found in Phase II: Session 10, Part 3 and in Lorena Stoves.

Assist the groups in:

* Excavating pot holes, tunnels and chimney holes
* Cutting dampers
* Finishing the stoves

Encourage the groups to apply a protective coating to the stoves (refer to Lorena Stoves for details).

Stress the importance of using alternative materials for construction of chimneys (See Part One).
