Electricity is the most important carbon-reducing industry, and coal power (thermal power generation) is the largest form of energy in China's current energy structure. Coal produces carbon dioxide, sulfur dioxide, nitrogen oxides, and other toxic and harmful gases during the combustion process, and carbon emissions from the power sector account for more than 1/3 of all carbon emissions. China is committed to reaching "carbon neutrality" by 2060, and carbon reduction is the focus of all efforts. Most foreign cities have adopted the energy structure of "renewable energy + energy storage system", and through biomass power generation, cogeneration and other technological routes, the development of zero fossil energy in a phased manner.
Green thermal power plants need to adopt advanced and efficient dust removal, desulfurization, low-NOx combustion, denitrification, wastewater treatment, comprehensive utilization of ash, on-line monitoring and other new environmental protection technologies, and strictly control the concentration of pollutants discharged and the total amount of emissions. Using the visualization technology of Toufou software for online monitoring, users can access the 3D visualization system anytime and anywhere by opening a browser, which reduces the pressure of purchasing high-performance hardware costs, and secondly, breaks the limitations of the management scenarios that users used to manage in the monitoring room, and also improves the monitoring efficiency.
Green Thermal Power Plants
Thermal power generation is mainly coal-fired, oil-fired, and gas-fired according to the fuel used. The main equipment systems include fuel supply system, water supply system, steam system, cooling system, electrical system and other auxiliary processing equipment. Through the Tupu software, information about the plant as a whole and the operation of key equipment at the site can be displayed in real time on the Web side, allowing plant operation and maintenance personnel to monitor the operation of the fuel and steam systems and other systems in real time through the visualization of the large screen, for comprehensive and efficient management. The role of coal power is changing, gradually transforming from baseload power to peak power, from scale to intensification, and from economy to high-quality development. The essential attributes of coal power will also be from a single electrical energy producer, gradually transitioning to build a new energy power system enabler, assisting the new energy into the growth period, and realizing the smooth upgrading of the power grid.
The traditional coal-fired thermal power plant coal conveyor system main equipment configuration: coal storage yard, coal feeder, belt conveyor No. 1, tilting roller screen, ring hammer rough breakers, belt conveyor No. 2, ring hammer fine breakers, belt conveyor No. 3, iron removal, dust collector, sampler, unloader, boiler coal storage silo.
Raw coal is processed into a form suitable for combustion in modern power boilers (e.g., coal is ground into very fine pulverized coal), and then sent to the boiler for full combustion with the help of hot air, so that the chemical energy stored in the fuel is transformed into heat energy; the water in the boiler absorbs heat and becomes saturated steam under a certain pressure, and the saturated steam continues to be heated to superheated steam in the superheater.
Steam through the turbine and the thermal energy into rotating power to drive the generator output of electricity. By the 1980s, the world's best thermal power plants had an efficiency of 40%, i.e., 40% of the heat energy in the fuel was converted into electricity.
The Plant Information panel on the left side of the big screen shows the main information about the project, including: Plant Information, Operating Information. The operation information can be viewed in real-time cost, revenue and profit dynamic trend graph. The right side shows the number of days of safe production, which records the cumulative time of safe commissioning of the plant. Equipment operating efficiency and production information***The same monitor the real-time operating efficiency and operating parameters of boilers and turbine generator sets. By real-time data-driven regulation of the equipment, low-carbon operation of the equipment can be realized. Nowadays, power companies are constantly exploring new technologies to reduce carbon emissions.
China Resources Power adopts the advanced "tower in one" technology, which combines the chimney and cooling tower of the thermal power plant into one, and utilizes the cooling tower to discharge flue gas. Cooling tower has the original cooling function, but also can replace the chimney discharge desulfurization of clean flue gas, this technology can be done not only to achieve the flue gas emission standards, but also to achieve harmony and unity with the cityscape. According to the introduction of power plant technicians, the project uses efficient electric bag composite dust collector, and at the same time the construction of desulfurization, denitrification facilities; boiler flue gas through the electric bag filter, desulfurization and denitrification facilities, so that the concentration of flue gas emissions are controlled at 20 micrograms per cubic meter for the following, sulfide and nitrogen oxides emission concentration to meet the latest national emission standards, the production of the enterprise on the city's air quality impact to a minimum.
Intelligent personnel control
Low-carbon operation of power plants requires not only starting from the equipment, but also improving the efficiency of the personnel and reducing the incidence of accidents. Based on the UWB positioning base station or other positioning hardware foundation, real-time positioning visualization function of the employees in the plant is realized in the 3D scene, so that the employees can't touch the fish during working hours.
Electronic Fence is a state-of-the-art perimeter protection and alarm system. The electronic fence host adopts the advanced perimeter security concept of "blocking as the main, alarming as a complementary", and sets the "deterrent, blocking, alarming as the main" as the main security system. "Deterrence, blocking, alarm, security" in one. When the staff in the dangerous equipment near the inspection, you can set the alarm distance, to avoid the staff mistakenly enter.
Enterprises are free to set alarm types according to the production situation, such as crosstalk, stranded, overstaffed, understaffed, intruding, and static timeout alarm types.
Combined with Intelligent Surveillance for further confirmation of employee behavior, Tupu software seamlessly combines HTML5 multimedia features, supports integration of various video resources to form a unified video stream, and allows you to mark camera objects on 2D and 3D situational maps and correlate them with their video feeds, and then interact with the scene to retrieve the corresponding surveillance video.
Low-carbon video is the most important part of the system.
The implementation of low carbon technologies is a complex process, and many organizations will terminate due to employee non-cooperation. Fine-tuned personnel control can achieve twice the results with half the effort, and efficient work can complement the implementation of low-carbon technologies to promote the realization of green thermal power plants.
Since China's participation in the Paris Agreement, indicating the determination to reduce carbon emissions, the country's attitude towards the higher carbon emissions of thermal power has also changed very significantly, eliminating backward production capacity, ultra-low emission transformation has become the thermal power industry must follow the guidelines. Flexible business adjustments are made according to different regional electricity prices, coal price levels and local power demand and load conditions, scaling down the amount of thermal power in areas with low electricity prices and low demand for electricity, eliminating backward production capacity of thermal power that is highly polluting and has a low number of hours of utilization, and concentrating the advantages of thermal power in areas with high demand for electricity and peak demand.
