The 80,000 tons/year pyrite acid production system of the Sichuan Sulfuric Acid Plant was designed by the Seventh Design Institute of the Ministry of Chemical Industry. There are two systems in front of the drying tower, each with a scale of 40,000 tons/year. The sulfuric acid waste heat power generation design is an F-300 medium-pressure forced circulation waste heat boiler, equipped with two Cl-35/5 steam turbines and two steam turbine generators. In March 1976, unit 2 of the sulfuric acid waste heat power generation unit was successfully tested and officially integrated into the power grid for operation. The power generation load could reach 800 or 1,000 kilowatts. By the end of 1977, a total of 2 million kilowatt hours had been generated. In February 1978, unit 2 was shut down for maintenance, and unit 1 was connected to the grid, generating 2.52 million kWh of electricity throughout the year. In 1979, Yueyue began to generate electricity with dual units, with a maximum load of 950 kilowatts and an average load of 1,462 kilowatts. It can not only satisfy the electricity consumption of this sulfuric acid workshop. . To meet the needs of kilowatts, part of the remaining electricity is sent to other workshops, which can ensure the continuous production of sulfuric acid when the power grid is scheduled to be shut down for maintenance. The Sichuan sulfuric acid plant's waste heat power generation has been operating from a single machine connected to the grid to a dual machine connected to the grid. By the end of 1979, it had generated 9 million kWh and supplied 8.76 million kWh of sulfuric acid. Based on the comprehensive electricity price of 0.09 yuan/kWh, the value was 788,400 yuan. Based on the coal consumption of similar generating units of 0.8 kg/kWh, it is * * Saved 7,008 tons of standard coal. In 1979, it generated 5.08 million kilowatt-hours of electricity and supplied 4.72 million kilowatt-hours of electricity to sulfuric acid, which is equivalent to 50% of the annual electricity consumption of sulfuric acid.
