Phase change heating furnace

A phase transition heating furnace comprising a steam generator, a heat exchanger, a burner, and a controller, the boiler shell type steam generator and the pipe shell type heat exchanger are arranged as upper and lower split body, in which a plate pipe is arranged inside the pipe shell type heat exchanger, the inlet of the plate pipe is provided with a flux controller, and the flux controller is connected with an electric valve and a working medium inlet joint pipe. The boiler shell type steam generator is located in the lower part of the pipe shell type heat exchanger, and is softly connected with the heat exchanger. The furnace is of split structure, utilizes phase transition principle, can obtain very high outer tube heat transfer coefficient, has no oxidation corrosion, and the working life is long.
