Solar phase change heat storage type steam boiler system

The invention relates to a solar phase change heat storage type steam boiler system. A steam boiler is provided with an outer shell and an inner container, a heat preservation layer is arranged between the outer shell and the inner container, the inner container is filled with a phase change heat storage material, and a heat exchange pipe and an electric heating pipe are embedded in the phase change heat storage material. A solar power generation grid-connected unit drives the phase change heat storage type steam boiler to generate heat, water serves as a heating medium and is adjusted throughthe phase change heat storage material in the phase change heat storage type steam boiler, then the steam is generated, and the steam is continuously and stably provided for a steam user. Solar energy, the boiler technology and the phase change energy storage technology are combined, the effective utilization rate of energy is increased, the service life of the steam boiler is prolonged, good energy-saving benefits are a
