The invention provides an apparatus for keeping non-stop operation of steam turbines in
waste heat power plants of an iron and steel
plant; the apparatus comprises a
data acquisition device, a
decision support system, a
control system, a cooling and pressure-reducing device, a steam output adjusting valve block, a steam
discharge valve / water drain valve, a steam synchronization adjusting valve block, an emergency steam pipeline, emergency steam and
data acquisition line, which are connected with each other; a method for keeping non-stop operation of the steam turbines in the
waste heat power plants of the iron and steel
plant comprises the steps: the power plants are contacted with associated production
branch plants by using computer networks; the
waste heat power generation is equipped with the cooling and pressure-reducing device and used as the emergency standby steam source of the next level; the
data acquisition module acquires data of present values and accident values; according to the overhauling or accident conditions of the production plan, the
decision support system controls the steam flowing process of whole heating pipes by an acquisition module and the data of a
database itself, so that the stable continuous connection of the steam is achieved and the non-stop of the steam turbines can be guaranteed. According to the apparatus and the method for keeping non-stop operation of the steam turbines in the waste
heat power plants of the iron and steel
plant, the consumed time of frequent shutdown of the steam turbines is avoided, so that the steam turbines have long service life and are energy-saving and environmental-friendly.
