中文摘要：

生物质柴灶的使用已具有千百年历史,而传统生物质柴灶热效率低,多余热量未充分利用。本文在对传统生物质柴灶与普通多功能生物质柴灶的性能对比的基础上,设计改造了新式多功能生物质柴灶,并提出了适用于内部均设有水集热器的多功能生物质柴灶的相关性能指标。分别对普通多功能生物质柴灶、新式多功能生物质柴灶与传统生物质柴灶的热工性能进行了对比分析。综合生物质柴灶的性能指标可得,新式多功能生物质柴灶在保证火炕供热能力的基础上,比传统生物质柴灶的热效率提高了30.79%,且其具有比传统生物质柴灶及普通多功能生物质柴灶更好的热工性能,减少了能源消耗,适合广大农户的使用。

英文摘要：

The biomass stoves have been applied thousand years, while the thermal efficiency of the traditional biomass stove is low and redundant heat is utilized inadequately. In this paper, the new multifunctional biomass stove was designed and transformed based on the traditional biomass stove and the ordinary multifunctional biomass stoves. Furthermore, the related performance indicators were proposed, which are applicable for the biomass stoves possessing the heat collector inside. In addition, the ordinary multifunctional biomass stove and the new muhifunctional biomass stove were compared with the traditional biomass stove in the thermal performance. The results which were obtained by synthesizing the performance indicators showed that the thermal efficiency of the new multifunctional biomass stove was 30.79% higher than the traditional biomass stove based on the heating capacity and the new muhifunctional biomass stove had a preferable thermal performance than the traditional biomass stove and the ordinary muhifunctional biomass stove. Thus, the new muhifunctional biomass stove can reduce the energy consumption and is applicable for rural households.
