What Does a System Operator Do?

The operator of the waste heat and residual pressure utilization system refers to the person who operates the potential heat recovery and utilization equipment such as waste heat and residual pressure, and monitors and controls its operation. At present, the energy consumption of metallurgical industry production accounts for more than 10% of the total energy consumption of the national economy. At the same time, a large amount of exhaust gas is also generated. These exhaust gases contain high potentials such as thermal energy and pressure energy. In order to ensure the requirements of metallurgical production processes, the traditional method is to reduce the pressure and temperature of water and gas by means of release, decompression or spray cooling, so that a large amount of potential is not fully utilized, not only wasting a lot of pressure enthalpy and enthalpy, It also caused environmental pollution and noise pollution.

(1) Operate the dust removal equipment to remove the dust in the flue gas; (2) Regulate the residual (waste) heat boiler, vaporized water system and other equipment and auxiliary equipment to recover the thermal energy in the flue gas; (3) monitor the top of the blast furnace Working conditions, regulating the operating parameters of turbines, generators and auxiliary equipment, and using the residual gas pressure on the top of the blast furnace to generate electricity; (4) regulating compressors, gas turbines, generators and their auxiliary equipment, monitoring the temperature and pressure, Pressurized and warmed air and gas are sent to the gas turbine to mix, burn, and expand to drive the generator to generate electricity; (5) Monitor the temperature of the exhaust gas of the gas turbine, regulate the waste heat boiler, steam turbine, generator and its auxiliary equipment, and use the high temperature exhaust gas of the gas turbine Produce steam, and promote steam turbines and drive generators to generate electricity; (6) maintenance of equipment; (7) inspection of equipment to deal with hidden dangers and failures of equipment; (8) fill in duty logs and operating technical records.

At present, not only does the energy consumption level of Chinese steel enterprises differ from that of international advanced steel enterprises, but also the energy consumption level of Chinese steel enterprises also has a large gap. If China's steel industry is to achieve sustainable development and achieve national energy conservation and emission reduction goals, it is necessary to grasp and improve the utilization of waste heat and excess pressure.

With the advancement of science and technology and the increase of awareness of energy conservation and environmental protection, since the 1990s, various iron and steel joint enterprises across the country have invested a lot of capital and manpower, from metallurgical production processes such as coking, sintering, ironmaking, steelmaking, and rolling. In the link, where a large amount of waste gas, waste heat and residual pressure is generated, coke quenching waste heat power generation (CDQ), blast furnace top gas residual pressure power generation (TRT), gas-steam combined cycle power generation (CCPP), converter Exhaust heat waste pressure utilization system such as hood-type waste heat boiler and heating furnace to vaporize water to produce steam. The completion of these systems can meet 50% of the power needs of enterprises, and reduce greenhouse gas and dust emissions. According to statistics from the China Iron and Steel Industry Association, the utilization rate of waste heat and residual pressure potential in China's metallurgical industry has reached 70%, and the annual use of waste heat to produce steam can reach 40 million tons, which is equivalent to saving nearly 400,000 tons of standard coal. The annual energy recovery can reach more than 10 billion kWh. Practice has proved that the construction of the waste heat and residual pressure utilization system has shown the advantages of low cost, low energy consumption, and low pollution. It is to improve the comprehensive utilization of resources and energy conversion, promote the adjustment of energy structure, promote the upgrade of the metallurgical industry, and improve the competitiveness of enterprises. An important measure is an emerging and sunny industry in the metallurgical industry.

The waste heat and residual pressure development and utilization industry has spawned a new profession of "waste heat and residual pressure utilization system operator". At present, there are more than 20,000 employees, and it is on the rise. Therefore, the establishment of this new occupation and the establishment of corresponding national vocational skills standards are of great significance for regulating vocational training, accelerating the cultivation of such skilled personnel, promoting safe production, and achieving the goals of energy conservation and emission reduction.
