由河北省沧州地区泊头市新能源办公室承担的铸铁太阳灶项目,近日在铸造之乡泊头市文河镇试产成功了。该产品以灰口铸铁为原料,采用超薄型铸造工艺精制而成,其重量比国内同类产品降低约7%,灶面光洁度高,不用处理即可直接贴镀铝薄膜。该灶聚光性能好,采用偏轴聚光设计,焦距为750mm,焦斑直径为130mm,面积为2.2m~2。由于功率大,热效率高,在冬季环境温度为-5℃的雪地里,用35分钟就能把4.5kg水从3℃加热至100℃(不加任何保温措施)。由于采用螺杆手动跟踪装置,该灶
The project of cast iron solar stoves undertaken by Botou New Energy Office in Cangzhou, Hebei Province, recently succeeded in pilot production in Wenhe Town, Botou City. The product is made of gray cast iron as raw material and is made of ultra-thin casting process. Its weight is reduced by about 7% compared with similar domestic products. High surface finish of the cooktop can be directly attached to the aluminum film without treatment. The stove condenser performance is good, the use of off-axis condenser design, the focal length of 750mm, focal spot diameter of 130mm, an area of 2.2m ~ 2. Due to its large power and high thermal efficiency, 4.5 kg of water can be heated from 3 to 100 ° C in 35 minutes (without any insulation) in the snow with a winter temperature of -5 ° C. As a result of the screw manual tracking device, the stove
