Analysis Of China's Coal

China's coal-fired power saving potential exists, should tap the energy potential of coal-fired power plant, but explore the potential to take a scientific attitude.


A Chinese coal is essential at this stage Power supply .


China coal at this stage and for a long time is essential Power supply . First, China's coal is the worst use of fossil energy. Good coal for the metallurgical, chemical and civil, the remaining coal stone, in the coal, peat, lignite and coal, for electricity generation using coal-fired power plants. If the coal is not used for power generation, does not have many other uses. Second, China's coal power generation to bear the most difficult task. In a variety of power, first make nuclear power, hydropower, wind power, solar power generation priority power generation, hydropower, wind power, solar power has random, but does not meet the electricity needs of this random power. Large hydropower wet hair, dry hair Dry Season less; wind the wind on the hair, no wind, no-fat, low-fat; solar power with the sun on the hair, the weather is cloudy, not at all. Daihatsu other power supply, the coal would be less bitchin; other power less fat, the coal would Daihatsu. Coal into the power system to fill the power surplus and deficiency, essential to ensure a reliable supply of electricity power, bear the most difficult generation task. Third, China's industrial heat public buildings in Northern winter heating and residents rely mainly on coal-fired power plant with heat to provide low-cost heat source, coal-fired power plant's energy efficiency even higher than the most advanced ultra-supercritical Generator , And IGCC units, without coal-fired power plant, where the Chinese to find cheap, adequate heat it? Fourth, China's coal-fired power plants in support of China's first coal-dominated energy structure, ensure energy in a coal-based conditions to minimize the pollution caused by coal burning. This is because the power industry is best able to clean use of fossil fuels (coal) users, coal-fired power plants can minimize the fly ash produced by coal combustion, sulfur dioxide and nitrogen oxide emissions. As the largest user of coal, coal-fired power plant to become the best in all sectors of national economy and clean use of coal users. For this reason, the Chinese like to keep a coal-dominated energy structure, it must be kept to coal-based power structure. Even if future production of coal production reached its limit, in order to protect the environment, but also should minimize Other Dispersed coal sector, thus bringing together the supply of coal fired power plant. Coal consumption in China's current share of coal consumption is only about 50%, the future may increase to 80% to 90%.


Second, the development of China's coal analysis of the problems.


Reserves of energy resources from China and production, the most practical power source is coal-fired power generation, including coal-fired cogeneration. But for decades, blamed on the Chinese coal endless, and coal is a reality, economic, clean, advanced power supply made various different views, interference of China's power generation structure of implementation.


1. About "water main fire auxiliary" power long-term construction.


China's first five-year plan the construction of the power industry policy is "Huozhu water auxiliary." Plan said: To meet the industrial development, especially the new industrial zone construction, must strive to develop the power industry, the construction of new power plants and the original power station conversion. First Five-Year Plan period, the main power plant will be construction of fire (including heat and electricity co-production of thermal power stations), while conditions of use of existing resources, for hydraulic power station construction work, and to vigorously pursue investigations of water resources, active in the future to prepare conditions for hydropower development. Was to determine such an approach is pragmatic. In 1958, in the second five-year plan also proposed to implement "water main fire auxiliary," the long-term development approach advocated speeding up hydropower development, control the development of coal. As the actual implementation hindered the development of power industry, to the principle of power construction in 1961 will be replaced by "hydrothermal simultaneously, where there is more water out water", the actual implementation of the results or "Huozhu auxiliary water", water capacity proportion has not exceeded 32%.


2. Construction of power plants burning oil on the part of coal-fired power plant alternative.


China has long been short of petroleum, less gas-rich coal, in the construction of thermal power station has been dominated by coal-fired power plants. (ArticlesBase SC #3372113)

The Benefits of Renewable Energy Solutions

Some people may not want to admit it, but the world is slowly moving towards an energy crisis. Non-renewable resources such as fossil fuels are much closer than people think to becoming extinct. We have always known that the everyday energy we use is not unlimited, yet it is constantly being taken for granted. Oil, gas, power, even water has limited availability. Yet, we have not taken nearly enough precautions to deal with a very real threat of an energy crisis. When I say ‘we’, I am not referring to the governments of the world, but to all of us, the common people. We are the ones who can make a difference.

To neutralize this crisis, it is important that we learn to reduce our dependency on energy sources that are non-renewable and start focusing on energy solutions that can provide us with a continuous source of energy that will not exhaust any resources. There are 3 main sources of energy which fall into this category: hydro energy, wind energy, and solar energy.

First, let's look at hydro energy.

Hydroelectricity is the most widely used form of renewable energy in the world. It is typically generated on a large scale by way of hydroelectric dams. Although it is indeed a renewable source of energy, hydro energy comes with some drawbacks. Hydroelectric projects have been known to have negative effects on surrounding aquatic ecosystems. One example, is there are studies that have shown that dams along the Atlantic and Pacific coasts of North America have reduced salmon populations due to their preventing access to spawning grounds upstream. A major disadvantage to hydroelectricity although rare, is the risk of dam failure. In Southern China, the Banquio Dam failure resulted in the deaths 171,000 people and left millions homeless. Although it is an effective source of renewable energy, it is not as environmentally friendly as the other 2 main sources of renewable energy, wind and solar power.

Let's look at wind energy.

Windmills have been around for thousands of years. They are older than electricity itself. In pre-industrialization times, they were used to propel sailboats and ships, they were used to pump water, and they were used as a means of natural ventilation in buildings.

Wind power has many advantages: It causes absolutely no pollution whatsoever. It consumes no fuel and has practically no effects on the environment at all. Wind energy can help generate tonnes of megawatts of electricity. When employed at home, it can help do away with conventional power sources which will reduce your electricity bill and can even eliminate it altogether. Wind power is an excellent source of continuous, renewable energy.

Finally, let's look at solar energy.

Solar power is by far the most available source of continuous, renewable energy on the planet. It is easily capable of providing the world's total current energy demand many times over. Solar power solutions at home are another way of dramatically cutting down power bills or even completely eliminating them altogether. Also, solar power has no effect on the environment whatsoever. It is the most environmentally friendly source of energy in the world.
