省柴灶是利用热学原理，最大限度地多利用燃料燃烧后释放出的热量，从而提高处的热效率，达到节约燃料的目的。如何提高省柴灶的热效率呢？根据我多年的探索和实践认为，关键是三个条件：一是必须要使燃料充分燃烧，才能释放出最多热量，这是首要条件；二是要尽量增大锅的受热 Provincial firewood is the use of thermal principles, to maximize the use of fuel combustion after the release of heat, thereby improving the thermal efficiency, to achieve the purpose of fuel savings. How to improve the thermal efficiency of firewood stove? According to my years of exploration and practice, the key is three conditions: First, we must make the fuel fully burned to release the most heat, which is the first condition; the second is to try to increase the pot heat
