The invention discloses an energy-saving environment-friendly straw furnace, and relates to the technical field of straw furnaces. The energy-saving environment-friendly straw furnace comprises a shell, one side of the shell communicates with a water inlet pipe, the end, positioned inside the shell, of the water inlet pipe communicates with a water jacket layer, moreover, the bottom of one side ofthe water jacket layer communicates with a water outlet pipe, the end, far away from the water jacket layer, of the water outlet pipe penetrates through the shell and extends to the outside of the shell, an inner container is fixedly connected inside the water jacket layer, and a transverse net is fixedly connected between the bottoms of the two sides of the inner wall of the inner container. According to the energy-saving environment-friendly straw furnace, a fan is installed on one side of the shell, an air outlet of the fan communicates with the inner container, and air is blown into the inner container by the fan, so that the burning effect of straw is improved; and the water jacket layer is installed inside the shell, the water inlet pipe is installed on the top of the water jacket layer, the water outlet pipe is installed at the bottom of the water jacket layer, the inner container is installed inside the water jacket layer, water in the water jacket layer is heated through theheat of the inner wall, so that the waste of heat is avoided, and resources are saved.
