2.1 Breve descripción de la Tecnología

Definición de la Tecnología:

A brick stove that is built into the existing internal wall, that will heat the two rooms and can be used for cooking.

2.2 Descripción detallada de la Tecnología

Descripción:

The 2-room stove is a brick based structure that filters hot air into a second room, hence maximising the heating potential of the fuel. The basic stove is built of fire bricks, house bricks, cement and coated with a natural mix of straw and mud. It is a traditional concept based upon former soviet stoves, that was modernised and adapted to improve the energy efficiency, and make use of the materials that are available to the people. It is able to burn coal, wood, and tapac, and is designed to reduce the amount of natural resources used to meet the household energy needs.

Purpose of the Technology: The purpose of the 2-room stove is to replace the traditional cast iron pig style of stove, with a more modern and energy efficient stove that can be used effectively for cooking and the heating of two rooms. The 2-room stove is designed to filter the hot air between the rooms and the use the bricks as a thermal sink for heat retention. As most of the houses are made of mud bricks, the heat from the stove will conduct through the walls, which will act as radiators to emit warmth into the room. The 2-room stove also means that cooking activities can be conducted inside the house in a smoke free environment.

Establishment / maintenance activities and inputs: The stove requires basic training in construction by a skilled technician, however after a three day training course the local trades people are able to build their own stoves with limited supervision. The stove is constructed from 45 fire bricks and 400 household bricks, the hot plate and stove doors are bought second hand from the markets, and metal bars are used to reinforce the structure. There are two smoke vents in the wall between the two rooms to allow the smoke to filter its way along the snake like chimney until it vents through the roof. The final structure is coated in straw and mud which acts as an insulation layer.

Natural / human environment: There is a high reliance on natural resources in Shahtuti Bolo. The average family burns several tons of tapac (straw dung mix) and wood each year. The surrounding mountain area is sparsely vegetated and does not even provide enough fuel for the village during the harsh winter months. This is supplemented by buying wood from the neighbouring villages. One tapac weighs one kilo, this is organic matter that can no longer be used for soil enhancement, but for fuel purposes. It is estimated that the 2-room stove will reduce the amount of fuel burnt by 20-40% depending upon the household.

3.5 Grupo MST al que pertenece la Tecnología

• tecnologías de eficiencia energética

3.6 Medidas MST que componen la Tecnología

Comentarios:

Main measures: structural measures

3.7 Principales tipos de degradación del suelo encarados con la Tecnología

Comentarios:

Main type of degradation addressed: Wt: loss of topsoil / surface erosion, Wg: gully erosion / gullying, Wm: mass movements / landslides, Et: loss of topsoil, Cn: fertility decline and reduced organic matter content, Bc: reduction of vegetation cover, Bh: loss of habitats

Secondary types of degradation addressed: Bq: quantity / biomass decline

Main causes of degradation: soil management (Failure to use organic fertilisers), deforestation / removal of natural vegetation (incl. forest fires) (Removal of natural resources to meet local energy needs.), over-exploitation of vegetation for domestic use (as above), overgrazing (Areas became over grazed as productivity declined), disturbance of water cycle (infiltration / runoff) (removal of vegetation leads to increased run off from the mountain slopes.), poverty / wealth (There is a lack of money for investment), labour availability (Two thirds of the households in the village have people working abroad.), war and conflicts (There has been substantial political unrest in the area.)

Secondary causes of degradation: Heavy / extreme rainfall (intensity/amounts) (There is a perception that there are more extreme rainfall events.), population pressure (Popualtion in the area is increasing), education, access to knowledge and support services (Lack of knowledge on good land management.)

6.7 Fuerzas/ ventajas/ oportunidades de la Tecnología

Fuerzas/ ventajas/ oportunidades desde la perspectiva del usuario de la tierra
It keep the house warm and for longer. How can they be sustained / enhanced? Thermal insulation techniques and energy efficiency training may support reduced fuel use.
I do not have to cook outside in the winter months.
It is easy to clean.

Fuerzas/ ventajas/ oportunidades desde la perspectiva del compilador o de otra persona de referencia clave
It improved the household heating system dramatically, as the previous cast iron stove does not retain the heat after the fire dies. How can they be sustained / enhanced? The room could be insulated using traditional techniques or modern materials that are starting to appear on the market.
The brick design will retain the heat for several hours and will heat two rooms. How can they be sustained / enhanced? Doors and windows in the rooms could be sealed to prevent drafts.
The stove will last for 25yrs with minimal maintenance. How can they be sustained / enhanced? If the stove became popular a small brick making factory could be established.

6.8 Debilidades/ desventajas/ riesgos de la Tecnología y formas de sobreponerse a ellos

Debilidades/ desventajas/ riesgos desde la perspectiva del usuario de la tierra	¿Cómo sobreponerse a ellas?
It is expensive, and I need an expert to help me.	Remittances could be used to fund the initial set up costs.

Debilidades/ desventajas/ riesgos desde la perspectiva del compilador o de otra persona de referencia clave	¿Cómo sobreponerse a ellas?
There is a high initial investment that has required project funding.	Collective building of the stoves will reduce the cost. Micro-finance loans could be made available to help cover the initial costs.
The stove requires technical training in its construction.	A booklet could be produced to support self building of the stoves.
