Power the main way of energy saving and emission reduction
In China's power industry, thermal power enterprises are particularly important to produce clean energy from it is a big energy consumer, their waste emissions and energy conversion rates will directly affect the realization of China's energy saving and emission reduction goals. Thermal power Enterprise energy emission reduction of way main has following several: a,) through stop using part small thermal power unit and while construction big capacity, and low can, and efficient, and less emissions of unit, to reached structure Shang of optimization and the consumption; b) through development and application new of technology, and new of process and the equipment, to promoting thermal power enterprise in its field of technology upgrade, reached technology Shang of optimization and the consumption; c) through energy scheduling of measures, using information of means monitoring enterprise of desulfurization and coal of situation, Meet the management and optimization of consumption.
Power problems in the energy conservation and emission reduction
At present, under the Government's strong push, all large, medium and small thermal power enterprises are actively taking measures to achieve the goal of energy conservation and emission reduction, although under the joint efforts of Government and corporate energy-saving emission reduction is already paying off, but there are still some problems that cannot be ignored, the following will be discussed one by one.
Power saving long-term mechanism problem
China has always attached great importance to energy saving and emission reduction work, the State Council promulgated a special programme is also aimed at not only all walks of different features of the appropriate policies and legislation. However, power implementation of energy saving and emission reduction work at this stage is mainly relying on administrative laws and regulations, and so on, through market mechanisms, to promote energy conservation and emissions reduction efforts are not enough, there is no combination of various measures played an active role. Study and establishment of long-term mechanism of electric power energy saving and emission reduction, legal and long-term interaction between market mechanism to ensure energy saving and emission reduction objectives better and faster to complete.
Problem of electric power enterprise's economic benefit
At present, under the influence of the market environment, prices of electricity and fuel (coal) prices directly affects the electricity enterprises, especially thermal power enterprise's economic benefit. In recent years, with rising coal prices, sewage and water, and thermal power enterprise's efficiency problem. Coal price hikes for thermal power enterprises in recent years to bring the weight of direct impact on the realization of energy saving and emission reduction targets.
Electric power enterprise distribution
Thermal power enterprise's energy is mainly coal, resulting in its selected focus as the cost of coal, thus ignoring the environmental carrying capacity, thermal power enterprise groups has caused local air pollution, and destroyed a factory area of ecological environment.
Other issues
Thermal power enterprises energy saving and emission reduction work but also by the influence of many factors, such as desulphurization equipment of coal quality and performance, quality, and so on. Desulphurization equipment of poor quality, running experience, or the device is not operating properly can give effect of desulphurization of substandard coal of low quality leads to reduced heat, ash and sulfur content increases, this will not only seriously worn out equipment, also makes auxiliary power consumption increased power efficiency.
Discussion on the countermeasures of electric power energy-saving emission reduction
Strengthen macro planning and adjustment of industrial structure
For the power industry as a whole, planning is very important. Based on demand distribution of China's energy, electric power, electricity distribution and other characteristics of enterprises now, determine the best resource allocation scheme to determine the optimum energy flow and transport processes, build efficient and energy-saving unit, optimizing the structure of thermal power.
Increase renewable power (hydropower, wind power, etc) are also effective methods to promote energy conservation and emission reduction in the utilization rate, using a combination of administrative laws and regulations and market competition mechanism and improve production efficiency, promote energy conservation and emissions reduction, effective means of optimal allocation of resources.
Adjust management methods to improve the efficiency
Reasonable management tools is one of the most important ways to improve economic efficiency of enterprises, the same, the electric power industry energy-saving emission reduction can be implemented successfully and obtain a corresponding outcomes are closely linked with enterprise management tools. Management is divided into two levels: a) the administrative; b) generator management. We can according to the two characteristics to develop appropriate management measures, enhance employee awareness of energy saving and environmental protection, cultivate all consciousness of energy conservation and environmental protection; stopping part of small unit operation, strengthening the efficiency of the generator, to maximize energy configuration.
Adjusting the structure of electric power industry Power of scientific
Industrial electricity consumption is far greater than the proportion of other aspects of the use of power, the rapid industrial development was the root cause of rapid growth of electricity consumption. To dampen the rapid growth of electricity consumption, will proceed from the facts of the rapid industrial development, through the adjustment of the industrial structure to solve industrial problems of high power consumption and save energy.
Blindly led to build thermal power plant coal supply and demand out of balance, and extremely polluted the local environment. To achieve the goal of energy conservation and emission reduction to protect the environment, try to avoid disorderly established thermal power enterprises. Only by proceeding from the source of the problem, and rational planning, in order to fundamentally solve the problem.
Strengthen the emission control for thermal power enterprises
In recent years, although China's thermal power industry emissions of SO2 and inversely proportional to the power plant generating capacity, but the air pollution situation in China still cannot be ignored. Country's acid rain area has one-third per cent of total land area, and China is the country with the largest emissions of SO2. Therefore, the power plant desulphurization equipment is particularly important, want to reduce emissions, and desulfurization equipment must be properly run. However, burning coal is more than just produce SO2, while producing CO2 and NOx. Excess emissions of CO2 will cause the greenhouse effect, the environmental problems of global warming are also cause for concern, excess emissions of NOx can also cause pollution to the environment. Therefore, the thermal power industry in desulfurization, denitrification, carbon dioxide removal for the ultimate goal.Application of energy-saving heat exchanger problems should not be underestimated, plate and shell heat exchangers as well as pillow plate heat exchangers greatly enhanced the application of energy-saving effect.
At this stage, while the construction of flue gas desulfurization equipment of thermal power enterprises are explosive development, but there are some environmentally friendly thermal power enterprises and legal awareness is not strong enough, desulphurization equipment design and build quality is not high enough, on the experience of inadequate and desulfurization of these result in the device to function improperly or not up to standards, and so on. Thermal power enterprises should strengthen the internal management of enterprises must strengthen management of coal quality, must strengthen the desulfurization equipment bidding management must be strengthening reliability management of desulphurization equipment, only to do it all four must, thermal power companies can really achieve energy saving and emission reduction targets. Meanwhile, strengthen enterprise's statistical work of energy saving and emission reduction, scientific monitoring of the effect of energy conservation and emission reduction, also promoted to the complete energy-saving emission reduction target.
Improve laws and regulations to strengthen supervision work
Sound power law of energy saving system, to detect and eliminate the existing laws that are energy-saving and emission reduction policies and requirements are not met, maintaining consistency of related laws and regulations and energy conservation and emission reduction, in order to better implement and achieve energy conservation and emission reduction. While, also to strengthened supervision system, stole row gaseous pollutants of behavior once found will serious processing, and held related personnel of responsibility, full supervision related thermal power Enterprise desulfurization governance of work progress, promoting thermal power enterprise according to corresponding of requirements completed desulfurization task, firmly investigation not by legal regulations requirements for production of thermal power enterprise, only such, to promoting thermal power Enterprise strictly of by chapter production, promoting China power energy emission reduction by expected of track for.
Thermal power enterprises as the backbone of China's power industry, which relies on the conversion of heat energy to produce clean electricity, and heat production is an energy consuming process. Primary energy consumption in thermal power plants are coal, in the process of converting it into electricity, will produce various gases which pollute the environment, these gases cause acid rain, greenhouse effect, and so on. To really achieve the goal of energy conservation and emission reduction in electric power industry, it is necessary to improve the long-term mechanism of energy conservation and emission reduction, combining the use of laws and regulations and market instruments, auxiliary to increase the country's macro programming, adjust the overall structure of electric power industry, power industry structure, and also tighten controls on emissions of polluting gases and formulate relevant laws and regulations, strictly monitored and implemented in earnest. Doing so can really inhibit thermal power plant emissions, to tackle the source of the problem can be faster and better achieve the goal of energy conservation and emission reduction.
