2. Description of the SLM Technology

2.1 Short description of the Technology

Definition of the Technology:

The technoloigy is engineered in such a way that there will be less consumption of wood and less emission of smoke.

2.2 Detailed description of the Technology

Description:

The technology document is entitled"improved Stove In Rural Areas".This technology brings more effective way of cooking compared to the old one.Here,unlike the rural areas wood consumption is lesser and wood consumption is lesser and there is also proper outlet of smoke produced.In the old stove more wood and fuelwood were consumed and smoke were accumul;ated in the cooking site which is the kitchen.Thus it reduces health hazards.
Here we have a single input area to enter the fuelwood for a pair os stoves. This is done because the heat pressure is not allowed to escape and the same heat produced shifts in the other stove and helps in heating.

Purpose of the Technology: The purpose cof the technology was to reduce the health hazards due to accumulation of smoke in the kitchen to reduce the fuelwood consumption, to save time in cooking and hence to maintain a smoke free zone.

Establishment / maintenance activities and inputs: The plant was first initiated by VDC in magh(2068B.S) by the assistance of Remerick Chyamrangbesi VDC and other co operatives.The first step was that labourers and technicians were given training an how to set up the stoves.Then they were assigned to construct it in homes.The labour charge and wages were covered by the organisation.The skills were not hightech so the skill was passed to the individuals of house and the maintenance was done.
Also, the organization send a person per year to if the stove is in proper working condition or not.

Natural / human environment: The technology mainly focuses on the health of the people exposed due to the indoor pollution.Since there was proper outlet no smoke was trapped inside which massively reduced air pollution.Besides less firewood was consumed,hence reducing the rate of deforestation and smoke emission.Also the ashes obtained from the burning firewood was a good fertilizer.

Technical specifications (related to technical drawing):

Two stoves are attached and firewood you require for first stove with input only.Heat is transferred to another stove aswell.It works on the principle of heat entrapment.

Location: Chyamrangbesi. Kavre
Date: 3/12/2012

Technical knowledge required for field staff / advisors: low (field staffs taught the technique to local people)

Main technical functions: increase in nutrient availability (supply, recycling,…)
Secondary technical functions: increase in organic matter, promotion of vegetation species and varieties (quality, eg palatable fodder), reduction of dry material (fuel for wildfires)

Structural measure: Soil shape
Vertical interval between structures (m): S,C,E

Structural measure: Iron,Chimney
Vertical interval between structures (m): O

Construction material (earth): soil excavated

2. Construction magh 2068
3. Final Jestha 24,2069
4. Materials cost

4.4 Costs and inputs needed for establishment

Specify input Unit Quantity Costs per Unit Total costs per input % of costs borne by land users
Labour Labour unit 1.0 400.0 400.0
Total costs for establishment of the Technology 400.0
Total costs for establishment of the Technology in USD 400.0

4.5 Maintenance/ recurrent activities

Activity Timing/ frequency
1. Monitoring

4.6 Costs and inputs needed for maintenance/ recurrent activities (per year)

Comments:

Machinery/ tools: Hand hoe
Labours as raw materials and ingrediaments were locally available, and hence free.Thus expenses was mainly on labour charge.Mininmum quantity of iron were used but so it was negligible.

4.7 Most important factors affecting the costs

Describe the most determinate factors affecting the costs:

Labour Skills: Initially the skilled people were hired to construct the stove and then the skills were acquired by the villagers so thet they can themselve make it onwards.The raw materials required were locally available which reduced the cost.
