In the 100-meter underground of the Lingdong Mine of Huaneng Coal Company, the largest underground mine in Northeast China, the shearer rotates rapidly, and high-quality coal is stripped off the coal wall; In the screening workshop, the workers efficiently hand-select gangue and remove impurities such as sediment; At the loading station, from the beginning of the year to February 2, the special coal train loaded with 26,098 cars of coal lined up in a long line and drove to various places for ......
Continuous cold waves, heavy snowfall, icy roads, and escalating challenges in keeping warm and supply. In the critical period of the peak winter, the units of China Huaneng units are in full swing, and they should be used to increase production capacity and transportation, just for the units to be able to withstand and stabilize. On the front line of guaranteeing supply, Huaneng people are the guardians in the wind and snow, ensuring that the people are safe and warm in winter.
Inner Mongolia: Do everything possible to ensure the "rations" of the unit
On the white coal road in the early morning, Cao Xingming, the fuel director of Huaneng Dalat Power Plant, and more than 20 commandos who de-iced and melted snow and ensured supply were constantly throwing snow melting agents, and thick hoarfrost formed on their eyebrows and eyelashes.
Recently, heavy snow hit Ordos again, Huaneng Dalat Power Plant 8 units use a large amount of coal, the coal mine loading points are scattered, the road from the power plant is far away and mostly rugged mountain roads, ice and snow road closure, coal transportation is urgent. After two days of intense work by the commandos, 16 coal roads leading to the power plant were snowmelted and de-iced, and more than 100 kilometers were dredged. At the same time, the power plant carries out 24-hour coal intake, safe unloading and unloading of coal yards, and coal quality supervision implements "white + black" rotation on duty. The cantilever belt of the No. 2 bucket turbine of the first and second phases of coal conveying suddenly withdrew from operation, and Qu Feng, a member of the commando, lifted the aluminum ingot, moved the heating plate, and lowered the rubber material in the extremely cold weather of minus 29, so that the turbine resumed normal operation 2 days ahead of schedule.
In Bayannur City, when the temperature was at a new low since the beginning of winter, Huaneng Linhe Thermal Power Plant received a notice that due to the sudden failure of the heating unit of another enterprise in the area, Huaneng Linhe Thermal Power Plant needed to immediately expand the heating connection area.
In the face of the sudden doubling of the heating area, the employees of the fuel department of the power plant immediately took action, and everyone rushed to the distribution center, the train departure station, the surrounding coal yards and other places to successfully finalize a car coal contract, more than 20,000 tons of coal by car and more than 17,000 tons of coal by train within 3 days, and the coal inventory continued to increase.
Ilatu, an employee in charge of the management of the power plant's coal yard, simply "lived" in the coal yard these days. "Why isn't it cold? My feet are numb, but the crew is waiting for the 'rations' to heat everyone, which cannot be delayed. On a winter day of more than minus 20 degrees Celsius, he shuttled between various coal trucks, holding a law enforcement recorder to take pictures and archive them. He can judge the quality of the coal at a glance, and the blending of coal is more accurate and efficient.
From January 1 to 23, the 50 units of Huaneng North Company operated for a total of 183 hours under all working conditions, and the cumulative power generation capacity exceeded 7.3 billion kWh, an increase of 14 percent year-on-year7%, with a total heat supply of more than 12.36 million GJ.

Hunan: ".Full fire"Guard10,000 homesLights
Recently, the northern Hunan region ushered in the first snowfall this winter, as the largest thermal power plant in Hunan, Huaneng Yueyang Power Plant 6 units "full firepower".
Luo Xingwang, who was in charge of the inspection of the power plant, found that the balance baffle of the No. 2 furnace was frozen and stuck, and the unit was in a state of deep adjustment at the moment, which led to a large deviation in the reheating temperature. On the 50-meter-high boiler platform, the cold wind was biting, Luo Xingwang's hands were red from the cold, and he held back enough strength to clean the baffle, and after half an hour, the position of the baffle was restored to normal, and the reheating temperature of the unit gradually improved.
On the wharf of the Yangtze River, strong winds above level 6 blow frequently, and the coal unloading equipment has problems such as belt slippage, deviation, and coal blockage, which makes the coal unloading "worse". Through the linkage of multiple departments and the efforts of all employees, the power plant has been fighting on the front line of thermal coal supply, and has successfully completed the "military order" of coal inventory in the peak winter. From January 1 to 24, Huaneng Yueyang Power Plant has completed a cumulative power generation of more than 5500 million kWh, heat supply 7560,000 tons, with a total of 36 coal unloaded40,000 tons.
Shandong: IcebreakerLack of securityGuaranteed supply
Huaneng Qingdao Thermal Power Plant is the main heat source in the western urban area of Qingdao West Coast New Area, and the two newly put into operation of 350,000 (unit?) Combined heat and power units are under pressure to generate electricity. Outside the power plant, after a rain and snow, the water remaining on the No. 0 belt turned into ice overnight, making the belt unable to start, which will seriously affect the fuel unloading work. The fuel department quickly started the "icebreaking operation", and everyone was "cold" by the sea breeze in a few minutes at the seashore of minus 11, but everyone still gritted their teeth, picked up a sledgehammer to smash the ice, and picked up a shovel to clean up the broken ice. After four teams took turns to fight, the 545-meter-long ice was all cleared, and the first step of the unloading work was started.
In the power plant, Chen Hongguo and Zhou Bing of the operation department led the squad leaders to inspect the electric heating of the 10-furnace ash conveying system, and found a wire that was falsely connected due to aging from the bundle of cables like a cocoon, and timely overhauled and solved a "roadblock" that affected the safe operation of the equipment. From January 1 to 23, the power generation of Huaneng Qingdao Thermal Power Plant increased by 49% year-on-year; The new heating area was 7 million square meters, and the heat supply increased by 241% year-on-year.

XinjiangWind and snow trek to protect the operation of the wind farm
In the Altay region of Xinjiang, the maintenance road of the Huaneng Burjin Wind Farm has been covered with snow, with a maximum snow depth of 35 centimeters. At this time, the weather is minus 25, and the wind farm operator Wu Liken is de-icing the anemometer outside the 100-meter-high nacelle against the cold wind, and the icy cold wind keeps blowing on his face.
The Chinese New Year is coming soon, and we must ensure the safety and stability of the equipment of the wind farm at this critical juncture. Wu Lican said.
Due to the serious snow on the road, the maintenance vehicles were deeply immersed in the snow, Zhao Changxing, the person in charge of the Burjin Wind Farm, organized personnel and mechanical vehicles to carry out ice breaking and snow removal operations, and the operation and maintenance personnel dug the snow with their bare hands.
