Abstract

The invention discloses an automatic control method for blast furnace top pressure in blast furnace coal gas residue pressure electricity generator, it uses automatic control software to realized the fluctuating real-time automatic control of pressure, thus ensures the TRT appliance can meet the demands of blast furnace refining process extremely. The method includes: (1) establishes mathematics and physics equation; (2) Xi parameter calculating and switching algorithm; (3) establishes automatic control system; (4) works out control software according to mathematics and physics equation and specialist algorithm. The invention can enhance the scientific content of TRT appliance product, enhances the competitive power of it. It solves difficulty in variable flow calculation and control technology, changes the analog control into digital control, and realizes the on-line supervising of pressure in TRT appliance.

Description

technical field [0001] The invention belongs to the field of energy and power engineering, and relates to an automatic control method for blast furnace top pressure stability of a blast furnace gas residual pressure power generation device (Blast Furnace Top Gas Recovery Turbine Unit) (hereinafter referred to as TRT). Background technique [0002] The stability of the top pressure of the blast furnace in the TRT device refers to the characteristics of the fluctuation range of the top pressure, the recovery time of the top pressure fluctuation and the fluctuation trend of the top pressure in the blast furnace smelting process. The so-called computer control of the blast furnace top pressure stability of the TRT device refers to the real-time automatic control of the fluctuation of the blast furnace top pressure in the blast furnace smelting process through the application of automatic control software. [0003] the term [0004] TRT: The blast furnace top pressure power reco...
