The invention relates to an ultra-supercritical thermal generator set coordinated control system, and belongs to the technical field of generator set coordinated control. An intermediate point temperature control system, a main steam temperature control system, a reheated steam temperature control system, an AGC control system and an ammonia spraying control system are all connected with a DCS module through a corresponding optimized system model controller. A separator outlet mean temperature value module, a separator outlet temperature setting module, a unit load module, and a separator temperature-to-coal-water ratio value correcting module are all connected with the DCS module through the optimized system model controller. The ultra-supercritical thermal generator set coordinated control system is simple in structure, reasonable in design and convenient to use, the purpose of coordinating unit loads is achieved by controlling output force of a boiler and a steam turbine, and the purposes of improving the unit load response speed and precision are achieved through a series of advanced algorithms.

The invention provides an off-the-road tyre low-external-temperature vulcanization method. According to the off-the-road tyre low-external-temperature vulcanization method, the tyre internal temperature vulcanization process remains unchanged, and the external temperature vulcanization process is adjusted, that is, low-pressure saturated steam at the pressure of 0.20 MPa-0.40 MPa and the temperature of 100 DEG C-110 DEG C is introduced into a vulcanization outer steam chamber; the vulcanized position of a tyre is transferred from the weakest vulcanized position to the center of the tyre through external temperature reduction, the pressure and temperature stability of internal and external mediums of the tyre are maintained until completion of vulcanization; and the tyre is taken out, and vulcanization is completed. The off-the-road tyre low-external-temperature vulcanization method has the advantages that the external pressure steam temperature is reduced in the tyre vulcanization process, steam is saved a lot, and energy consumption in the tyre vulcanization process is greatly reduced; the over-vulcanization degree of the tyre is reduced, the total vulcanization degree can be reduced by 20% or more, the overall vulcanization uniformity of the tyre is improved, the tyre quality is obviously improved, and the service life of the tyre is prolonged by 6%-12% compared with a tyre produced through a traditional isothermal and equipressure vulcanization process.

The invention relates to an energy-saving water treatment system and method for gasified concentrated water, and the system comprises an evaporative crystallization unit located at the downstream of a membrane concentration unit, and the evaporative crystallization unit is configured as follows: first-stage concentrated water sequentially enters a falling film module and a forcing module in a downstream manner; the first-stage concentrated water exchanges heat with second-effect and/or third-effect mixed distilled water and live steam condensate, then enters a first-effect falling film circulation evaporator and is evaporated in the first-effect falling film circulation evaporator according to a first saturated steam temperature based on corresponding pressure of gas-phase secondary steam; secondary steam generated by the first-effect falling film circulation evaporator serves as a second-effect heat source to heat the second-effect falling film circulation evaporator. According to the invention, material components are estimated based on the gas phase evaporation temperature of each effect and liquid phase concentration analysis in the evaporation process, and the internal pressure of each evaporator is changed by setting the first saturated steam temperature, the second saturated steam temperature and the third saturated steam temperature, so that the steam heating efficiency is improved, the investment and operation energy consumption of the system are reduced, and the energy consumption is reduced. The system blockage is prevented.
