The system consists of two parts: heat pipe steam generator, steam and water separation device (drum). The heat pipe steam generator is a new type of steam generator, it has good thermal performance of heat pipe as heat transfer components. Heat pipe is heated by high frequency welding fin to heat transfer enhancement, thus the whole device of high heat transfer efficiency, compact structure, thermal fluid flow resistance is small, and because of the heat pipe heating and vaporization of the water were completed in a flue, and a steam-water separation is completed in the drum.
