Energy-saving steam engine plant with high-temperature protection function

The invention relates to the technical field of energy-saving steam engines, and discloses an energy-saving steam engine plant with a high-temperature protection function. The energy-saving steam engine plant comprises an adjusting mechanism and a linkage valve mechanism, wherein the linkage valve mechanism simultaneously controls the opening degrees of a water pipe valve and a gas pipe valve, controls the amount of ingoing water and the amount of ingoing gas, and extrudes the adjusting mechanism through inlet water, then the number of heated heat exchange tubes is controlled by transmitting a signal, and meanwhile, the heat exchange tubes corresponding to water are burned by the amount of the ingoing gas. According to the energy-saving steam engine plant, the adjusting mechanism is arranged in a steam box, a controller is used for controlling burner nozzles corresponding to the high-temperature hot water in position to burn, the heat exchange tubes are fully utilized, meanwhile, the heat exchange tube segmen
