2. SLM技术的说明

2.1 技术简介

技术定义:

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

2.2 技术的详细说明

说明:

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.
