一铺好炕灶应该是:好烧、暖和、热得均匀和省柴。但要全面达到这些要求并非易事。去年末,黑龙江省对各地区推选的12铺炕灶,以及辽、吉两省的优秀灶各一铺进行了测试,测试结果表明:能较全面达到要求的炕灶一铺也没有(测试结果见附表)。由此可见,在北方地区推广省柴炕灶绝非是简单地按人为的想象去改变某些结构就可以达到的。必须按照科学程序,制订炕灶技术要求和测试方法,进行测试数据分析,根据要求和试验结果分析确定结构型式进行试验和验证后才能获得合理结构,从而研制出优秀的炕灶。本文从测试结果的数据来分析炕灶结构的主要问题。一、空气过量系数和化学不完全燃烧损失测验结果表明,从热损失来看,机械不完全损失一般仅在0.8～1.5％之间。所以此项损失是极小的,
A good kangzao shop should be: good burning, warm, heat evenly and save money. However, to fully meet these requirements is not easy. At the end of last year, Heilongjiang Province conducted tests on the 12-storey kang stoves selected by various regions, as well as the best stoves in Liao and Kyrgyz provinces. The test results show that the kama stoves that can fully meet the requirements do not have a shop See Schedule). Thus it can be seen that the promotion of provincial kang ki-kang in the north is by no means simply accomplished by changing some of the structures according to human imagination. Must follow the scientific procedures, the development of kama stove technical requirements and test methods, test data analysis, analysis and requirements of the test results to determine the structure of the structure to be tested and verified in order to obtain a reasonable structure, thus developed a good kang stove. This paper analyzes the main problems of the structure of kangzao from the data of the test results. First, the air excess coefficient and incomplete chemical combustion test results show that, from the heat loss point of view, the mechanical loss is generally only incomplete between 0.8 to 1.5%. So the loss is very small,
