On November 8, Zhang Weigang, a farmer from Zhangzhuang Village, Quzhou County, demolished a 6-year-old electric circulating pump on a heating stove and replaced it with a device called the super-powerful non-powered circulation pump. It is reported that this circulating pump is invented by Xu Yong-chi, a farmer from Shitou Village under the county, has been installed and used by hundreds of local families. At present, the domestic heating stoves on the market are installed according to the principle of thermal cycling. If they are not suitable, problems such as slow thermal cycling, poor heating effect, and serious energy waste will occur. In response to these problems, good study of farmers Xu Yong-chi, combined with reality, their own design, experiment, after hundreds of improvements and improvements, developed a water heater can only rely on the chimney can accelerate the water circulation speed circulating pump, named " Super non-powered heating circulating pump. " This circulation pump without electricity, long life, low cost and other advantages in one, not only improve the heating furnace heat transfer rate, reducing the high-temperature flue gas emissions, while increasing the cooling area, to solve the radiator on the heat Cold ills. Xu Yongzhi 44 years old this year, had invented the "on the heat switching multifunctional heating furnace" by the national patent, developed "Yongchun" heating furnace selling Handan, Xingtai and other places.
