China's first set of flue gas ultra-low emission systems has officially begun operation at Unit 8 of the Zheneng Jiaxing Power Plant. Following a major technical upgrade on a million-kilowatt coal-fired unit, its emissions now match those of natural gas turbines, reaching an internationally advanced level. This marks a significant milestone in the clean energy transition for coal-fired power plants and opens up new possibilities for sustainable development in economically vibrant eastern regions. The project holds great strategic importance for ensuring China’s energy security.
Initial tests after the system went live have confirmed that the emission levels meet the design specifications, proving the effectiveness of the technology. In line with its commitment to environmental protection and public health, Zhejiang Energy Group has continuously pushed beyond current national standards, becoming a pioneer in implementing "ultra-low emission" practices across the country. The company is accelerating its shift toward clean production, promoting the application of advanced coal power technologies and energy-saving environmental solutions.
After the implementation, the main pollutants from the coal-fired plant will meet the same emission levels as those from natural gas turbines. Specifically, particulate matter will not exceed 5 mg/m³, sulfur dioxide will be under 35 mg/m³, and nitrogen oxides will remain below 50 mg/m³. These levels represent a 75% reduction in particulate matter, a 30% decrease in sulfur dioxide, and a 50% drop in nitrogen oxides compared to the standards outlined in the "Emission Standards for Air Pollutants from Thermal Power Plants" (GB13223-2011) in key areas.
The ultra-low emission renovation project at Jiadian’s million-kilowatt coal-fired unit is the first demonstration initiative in the country to implement such stringent emission controls. With a total investment of 395 million yuan, the project uses advanced "multi-pollutant efficient synergistic removal integrated technology" to ensure that the emissions from coal units meet or even surpass those of gas units. The project was launched on August 13, 2013, and has since served as a model for future clean energy initiatives.
Zhejiang Energy Group has taken the lead in driving ultra-low emission transformations, introducing innovative technologies for clean coal combustion and emissions control. These efforts are opening new opportunities for the entire coal power generation industry and setting a strong example for sustainable development. Additionally, the ultra-low emission project for Unit 7 at Jiadian has entered the commissioning phase and is expected to become fully operational soon, further reinforcing the company’s commitment to environmental responsibility.
There are mainly two types of recovery winches: hydraulic and electric. Hydraulic recovery winches harness the hydraulic pressure from towing and rescue vehicles. Their hydraulic motors convert oil pressure into mechanical circular motion. They are often used in heavy - duty applications, boasting high pulling capacities. These winches can handle substantial loads, making them suitable for industrial settings, large - scale vehicle recovery operations, and situations where extreme power is required.
On the other hand, electric recovery winches are powered by electricity, typically from the vehicle's battery in automotive applications. They are popular among off - road enthusiasts for their ease of use and relatively simple installation. For example, the Rough Country 9,500LB PRO Series Electric Winch, with its 5.5HP motor and IP67 waterproof rating, is designed to perform well in tough off - road conditions like water crossings and muddy trails.
Recovery winches consist of several key components. A motor provides the initial power, which is then transferred through a gearbox that adjusts the speed and torque according to the task. The drum, around which a cable (either steel or synthetic rope) is wound, plays a crucial role in the winching process. The size of the drum impacts the winch's capacity. Additionally, a reliable braking mechanism is installed to keep the load secure during and after winching, ensuring safety for both the operator and the equipment.
In various industries, recovery winches are indispensable. In the automotive sector, they are used by tow truck operators to retrieve vehicles involved in accidents or stuck in inconvenient locations. Off - roaders rely on them to get their vehicles out of precarious off - road situations. In the maritime industry, they assist in ship mooring, anchoring, and salvage operations. In construction and mining, recovery winches help haul heavy equipment and relocate machinery in challenging work environments.
When choosing a recovery winch, factors like pulling capacity, cable material, and mounting options must be considered. The pulling capacity should be at least 1.5 times the weight of the load to be recovered. Steel cables are durable but heavy and may pose safety risks if they break, while synthetic ropes are lighter and safer, though more prone to abrasion. Mounting options can vary from front - bumper mounting for general recovery to receiver - hitch mounting for more versatile use. Regular maintenance, including checks of the cable integrity, motor functionality, and braking system, is also essential to ensure the winch's optimal performance and longevity.
