New Movement of "Green Thermal Power Plant"

After winter, the coal price continued to rise, and the production pattern of “market coal and planned electricity” put the domestic thermal power companies to face the dual pressures of energy conservation, emission reduction and cost reduction. In the face of difficulties, Huating Power Generation Corporation of China Hydropower Group seeks new breakthroughs in adversity and composes a new movement of “green thermal power plant” at the foot of Guan Shan.

Optimize each index to reduce production costs

At the foot of Guan Shan, a garden-style thermal power plant added a beautiful landscape to Hutong in Coal City. Into the Huating Power Plant, the white factory rooms are dotted with green pine trees, and the factory area is clean and tidy. The dust that is common in thermal power plants is lost there. This is a green and environmentally friendly power plant. What it eats is low-quality coal, which produces clean energy. Wastewater reaches zero emissions, and coal ash is reused. It is at the forefront of energy-saving emission reduction and loss reduction in the same industry in the country.

Faced with rising coal prices and shortage of power coal, the cost of power generation for power plants jumped from 58% at the initial stage of production to 80%, and Huating Power Plant could fully use boiler equipment to take advantage of “coarse grains” and further increase technical reform to make coal gangue The proportion of blended burned products rose from 5% at the initial stage of production to 30%. In the past four years, 120,800 tons of vermiculite have been cumulatively burned, saving fuel costs 5,179,100 yuan.

In order to solve the difficult problem of coal supply, material procurement personnel took the initiative to attack coal mines to understand the quality of the coal. “Hongyuan is responsible for fuel procurement,” said Hong Hong. “In 2011, our coal quality reached the highest level in the calendar year. Due to the high quality of coal and adequate combustion, the cost savings reached 7.48 million yuan.” In the coal storage yard, the reporter saw that each After coal trucks were brought into the factory, the coal ash that had landed on the ground was immediately cleared into large coal piles.

“Everywhere there are energy-saving and emission-reduction indicators, everyone shoulders heavy burdens,” which is a true portrayal of Huating Power’s “green power plant”. The 47 indicators such as power generation, coal consumption, fuel consumption, and water consumption are broken down into every link in the department and the production line. The “hard index” becomes a conscious action for employees to save energy and reduce emissions. At present, all the economic indicators of the company's energy-saving and emission reduction have completed a beautiful "pitch jump." The electricity consumption rate has dropped from 10.3% at the initial stage of production to 8.0%; the coal consumption rate has dropped from 441 grams per kilowatt-hour at the initial stage of production to 395 grams per kilowatt-hour, reaching the advanced level of the same type of domestic units, and the optimization cost savings have exceeded 30 million. Yuan, and created excellent performance in the industry with long-cycle safety production over 1,800 days.

Technical renovation and energy saving and emission reduction

Equipment optimization and scientific and technological innovation are the two tycoons that Huating Power has continuously reduced its energy consumption in recent years.

In recent years, Huating Power Generation Co., Ltd. has invested a total of more than 40 million yuan in energy-saving technological reforms. After optimizing the transformation of generator sets, it has saved 3.7 million yuan in electricity costs each year, and is located in the forefront of the same type of units in the country. After frequency conversion technological transformation of boilers and other equipment, the energy-saving rate reached 70%, the fuel-saving cost exceeded 4.168 million yuan, and the national energy-saving reward was ** 10 million yuan. After the operation and technological transformation of the unit's equipment was started, the province's power generation industry created a precedent for energy conservation, saving 600,000 yuan in out-purchased electricity.

The energy-saving and emission-reduction of power plants not only started from the “big place” but also focused on the small ones. They conducted energy-saving transformations on the main plant of the whole plant, the coal transportation system, and the lighting of the plant, saving 50,000 kWh of electricity annually. The company also carried out a series of energy-saving technological reforms in order to solve the problem of excessive silicon in furnace water, formed technical personnel for energy-saving research, conducted special technical research, and implemented more than 70 small-scale energy-saving technologies such as the transformation of rainwater recovery systems and chemical sampling water recycling. Renovation, annual water conservation of 20,000 cubic meters.

Green environmental protection to achieve energy-saving emission reduction and cost-loss reduction of win-win situation

"Green Power Plant" is a beautiful business card of Huating Power Generation Company. In the initial stage of construction, the company’s leading group decided to increase investment by 100 million yuan, introduce German air-cooling technology, replace 24 traditional cooling towers with 24 giant air-cooled fans, and achieve a water-saving rate of 86%. Accumulated water savings have been achieved since it was put into operation. 20 million tons, equivalent to the water consumption of Huating County residents for 6 years. At the same time, industrial waste water has been treated to achieve "zero" emissions, achieving a win-win situation in energy-saving and emission reduction and cost reduction and reduction of losses in the green environment.

At the same time, Huating Power Company invested 300 million yuan to complete the unit off facilities. The efficiency of de-NOx and denitrification efficiency reached 90% and 70% respectively. The efficiency of electrostatic precipitators was as high as 99%, and cumulative dust emission was reduced by 44,14 tons. The fly ash and slag were all recycled, and the comprehensive utilization rate reached 100%.

Huating Power Generation Company established the Gansu Energy Company by integrating the advantages of power plants and coal resources, forming an industrial structure in which the scale of China's hydropower investment projects in Gansu is concentrated, resources are intensive, advantages are centralized, and benefits are set. Recently, Gansu Energy Company and Shenhua Shendong Electric Power Co., Ltd. signed a strategic cooperation framework agreement for coal-electricity integration. Once again, the province's energy development has achieved the combination and strength of the central enterprises.

Faced with the development of the future, Zhang Weirong, general manager of Huating Power Generation Co., Ltd., said that creating a regional development strategy platform and achieving energy-saving emission reduction targets provides the best development opportunities for enterprises to become bigger and stronger. In the “Twelfth Five-Year Plan” period, we will build a 2×100 MW expansion unit for the second phase of Huating Power Plant to build a modern mine with Lingtai’s annual production capacity of 7 million tons, and achieve the target of 3.61 million KW of installed capacity, and actively develop wind power in the Hexi area. New energy sources such as photovoltaics are responsible for the economic and social responsibility of the central enterprises.
