在1980年10月于北京召开的全国农村能源学术讨论会上,中国农业工程学会邀请江西省代表向大家作了一次节柴灶的现场表演。在17℃的气温和初水温条件下,他们只用了8分钟、半斤木柴就烧开了10斤水,与会代表一致称赞这种节柴灶。在这次会议上表演的节柴灶(见附图),烟囱加高了一倍,为6.4米,并在烟囱里加了矿渣棉作为保温材料。八次实地测试证明这种灶省柴效果明显,平均热效率为40.7%(见附表)。做饭时,一般堵上地风道,采用投料口进二次风,烟火不会外冒。据江西省代表介绍,这种灶用砖250块(用坯也可);炉芯、炉篦、进科管和风阀等由县里统一安排生产,供应用户。由于这种
At the National Rural Energy Symposium held in Beijing in October 1980, China Society of Agricultural Engineers invited Jiangxi Provincial Representatives to give a live performance of firewood stove. At a temperature of 17 ℃ and the initial water temperature, they only spent 8 minutes, half a catty firewood boiled 10 pounds of water, delegates unanimously praised this stove. The firewood stove (pictured here) performed at this meeting doubled the height of the chimney to 6.4 meters and added slag wool to the chimney as a thermal insulation material. Eight field tests proved that this stove saves firewood and has an obvious effect with an average thermal efficiency of 40.7% (see attached table). Cooking, the general blockage to the air duct, the feed inlet into the secondary wind, fireworks will not take outside. According to the introduction of the representative of Jiangxi Province, this stove with bricks 250 (with the blank can be); furnace core, grate, into the Kemen and wind valve unified arrangements by the county production, supply users. Because of this
