The main cost of thermal power companies comes from thermal coal. Recently, due to the domestic and international economy, coal prices have continued to fall. Analysts believe that this downturn in coal prices will directly lead to the reversal of the dominant power of coal-fired games, and the thermal power industry will benefit. At the same time, the thermal power industry, which was previously forced to suffer long-term losses due to rising coal prices and lack of technological transformation, is also expected to launch a new round of technological revolution, which will help consolidate the results of energy conservation and emission reduction.
Coal slow-moving triggered coal price down
Since the beginning of the year, international coal prices have been falling, impacting the domestic market. The coal industry's inventories have risen rapidly. At present, Qinhuangdao's coal inventory is close to 9 million tons, and it broke through a record high last Monday. The national key power plant coal storage is also at the highest level in history. . Li Wei, director of the China Coal Transportation and Marketing Association, said that the coal industry has shown a loose balance. It is estimated that the total social inventory will reach 300 million tons, equivalent to one month of national coal consumption.
Analysts believe that the current decline in coal demand is the result of a combination of reasons. Affected by many reasons, China's thermal coal prices have plummeted. The latest Bohai Sea thermal coal price index released on June 25 showed that the comprehensive average price of 5,500 kcal thermal coal reached a new low, closing at 729 yuan per ton, the largest weekly decline since the index was released. Previously, the index has fallen by 58 yuan/ton for 7 consecutive weeks. As the price of thermal coal continued to fall sharply, coking coal and anthracite coal also began to fall.
The industry believes that in the past one or two years, the downward trend of coal prices is difficult to reverse, and the biggest beneficiaries of coal prices will be thermal power companies and ordinary people.
The new situation eases the dilemma of thermal power technology reform
It is understood that in the past three years, the coal industry has dominated the coal-electricity game. Driven by the rise in global resource prices, domestic coal prices have continued to rise, and coal-fired price linkages have not been implemented properly, resulting in a large profitability of the thermal power industry. decline.
According to data released by the five major power generation groups, the cumulative losses of the five major power generation groups' thermal power business reached 60.257 billion yuan between 2008 and 2010. The 2011 Annual Electricity Regulatory Report released by the SERC on the 27th disclosed that the five major power generations increased due to the increase in coal costs last year. The Group's (Huaeng, Datang, Huadian, Guodian, Power) power business totaled a loss of 15.117 billion yuan, and the national thermal power investment fell 26%. "Frozen three feet, not a cold day", the thermal power industry has fallen into such a serious loss quagmire for many reasons, but the coal price rise is the main factor.
Shen Zhongdong, chairman of Shenzhen Seneng Ketai Energy Management Technology Co., Ltd., who has long been engaged in research on energy-saving technologies in the thermal power industry, believes that in recent years, the marketization of thermal coal has led to a rise in coal prices year by year, power generation companies are generally losing money, and technical reform funds are seriously insufficient. The biggest obstacle for power plants to implement energy conservation and emission reduction projects. Although the state has introduced contract energy management methods to solve the technical difficulties of technical reform, but in the situation of being seriously depleted, most companies often have to give energy-saving technology reform to the urgent task of short-term full-fledged losses.
Analysts pointed out that this coal price will continue to decline, which will benefit the thermal power industry, and with the large-scale entry of electricity companies into the coal field, the self-sufficiency rate of coal will continue to increase, and the power of power generation enterprises will be significantly enhanced. Energy efficiency and emission reduction, such as efficiency and pollution control, are bound to pay more attention.
Characteristics and Advantages
(1) Intelligent control design: adjustable main parameter and secondary parameter automatically according to the weight of door leaves;
(2) Low noise: Special static sound track, integration of motor, worm-gear and retarder.
(3) Anti-clamping function: automatically reverse when meeting barriers;
(4) Unique electronic motor lock: the motor will lock up when the door is forced to open.(controlled by remote or switch)
(5) Tighten force: seal door when closed, power consumption approximately 10W under standby;
(6) Advanced brushless motor(36V,100W) can automatically adopt different heavy door leaves;
(7) Bi-doors inter-locking: one of the door leaves always remains closing;
(8)Safety sensor terminal: sensor stops working when door closed;
(9)Unique coating technology: never rusty;
(10)Easy and convenient to install;
(11)Working Process: when the door leaf closes to the right place, the door leaf will slightly shift to the door frame and the ground. The rubbers on the four sides of the door leaf will completely combine with door frame and ground, which ensures air tightness. When the door is open, the rubbers will separate from door frame and ground, which avoids contraction on the ground.
