BIOMASS STOVE: GUIDELINES FOR PROMOTING BIOMASS STOVE MAKING TO REDUCE HOUSEHOLD EXPENDITURE WITH CASE STUDY OF THAI WISDOM LEARNING RESOURCES AT BAN CHAI RAT, VILLAGE NO. 3, BAN LAMNAO SUB-DISTRICT, BANG KHAN DISTRICT, NAKHON SI THAMMARAT PROVINCE

Abstract

The objectives of this research article aimed to study the following: 1) Methods for making biomass stoves to reduce household expenditure, 2) Problems in making biomass stoves to reduce household expenditure, and 3) Guidelines for promoting biomass stove making to reduce household expenditure with a case study of Thai wisdom learning center at Ban Chairat, Village No. 3, Ban Lamnao Sub-district, Bang Khan District, Nakhon Si Thammarat Province. The research used qualitative research methods. The sample consisted of persons with knowledge about biomass stoves and persons who actually used biomass stoves, a total of ten persons. The results of the research found the following details: 1) The method for making a biomass stove to reduce household expenditure was found, and preparing equipment for making the stove would have helped reduce errors within work. Choosing stove materials should have been selecting the material with strong and durable properties and suitable for use. Assembling the stove included putting the steel cylinder of the stove onto the stove chamber that was already assembled, then welding the circular metal mesh to be leveled with the inlet of the refrigerant tank, and it would have been done. Efficiency trials indicated that it could be used for cooking instead of a gas stove; 2) The problem of making a biomass stove to reduce household expenditure was found to be a problem in selecting materials and equipment for building a stove. Some materials and equipment were quite difficult to find in the community. Safety problems in the production process indicated errors in checking tools before use and problems with durability; 3) Guidelines for promoting the making of biomass stoves to reduce household expenditure indicated that the design of building a biomass stove should have used heat-resistant materials that could be found locally to build the stove in order to reduce the costs of manufacturing. Additionally, the guidelines indicated that the stove might have been designed to be miniature and compact, suitable for carrying outside to create an interesting selling point.
