Since Prime Minister Li Keqiang in the "five" proposed "Blue Sky Wars," after the strategic plan states that China provinces and cities are doing to improve environmental protection. Jilin Provincial People's Government recently issued a "Jilin Province to implement the winning Blue Sky Battle three-year action plan to implement the program," coal-fired units will conduct a comprehensive reform.
Jilin Provincial People's Government recently issued a "Jilin Province to implement the winning Blue Sky Battle three-year action plan to implement the program" (hereinafter referred to as the "Program") said that before the end of 2018, the province's 300,000 kilowatts or more coal-fired units completed ultra-low emissions transformation. Continue to promote the 200,000 kilowatts class ultra low emission coal-fired unit renovation project, before the end of 2019, ultra-low emissions and strive to transform the province's total unit capacity of thermal power capacity of more than 75%.
"Program" also proposed to complete the transformation of ultra-low emission electricity generation units appropriate to increase the number of hours. Vigorously for shutting down environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance. Coal-fired generating units to increase the technological transformation efforts, speed up the heating pipe network construction, fully release and improve the heating capacity, eliminate coal heating boiler pipe network coverage and the range of loose coal. In areas do not have the cogeneration district heating conditions, the existing multiple small coal-fired boilers, alternative construction of large-capacity coal-fired boilers in accordance with the principle of equal volume. Before the end of 2020, within a 15 km radius of 300,000 kilowatts of heating and cogeneration power plant above range, in the case of cogeneration heating load to meet the heating needs, in addition to the need to retain the peaking boiler, coal-fired heating boilers and small coal-fired thermoelectric behind all closed down integration.
In addition, long-term control of total coal consumption in accordance with planning requirements, Jilin Province, to continue to reduce the amount of coal consumption, coal consumption in new coal projects to implement alternative reduction, by 2020, reduce the proportion of coal accounting for the province's total primary energy consumption to 63% the following. According to focus on the use of coal and clean use of principles, focusing on reduction of non-power coal, increase the proportion of electricity from coal, the state-assigned task is completed, the province's electricity by 2020, the proportion of thermal coal coal consumption reached more than 55%.
In the future, the province will carry out a comprehensive environmental aspects of governance, economic development and environmental protection go hand in hand.
Gas-fired steam coal fired boilers pattaya steam boiler and gas accounted for half of the market at any time, more and more national attention to environmental protection, gas steam boiler has been hit hard. In contrast, gas steam boiler by many users of all ages. In recent years, also vigorously promote the use of gas-fired boiler. Gas-fired steam boilers What are the benefits? Let us discuss with you today. Gas-fired steam boiler steam boiler and gas market accounted for half of the market, showing a trend of resistance of court, but in the long run, gas steam boiler will obviously be the only dominant market. Do not believe, look! 1. Purchase costs: Obviously, in terms of technical gas boiler and auxiliary aids far ahead of the gas boiler, and is equipped with a special gas burner. 1 ton steam boiler, for example, gas boiler about 30% higher than the gas boiler. 2. Construction cost: This cost mainly from the boiler room. As more gas steam boiler auxiliary equipment, boiler house construction should invest more money. Less gas boiler auxiliary equipment, automatic control operation, with automatic alarm and automatic protection, saving the cost of housing, safe and reliable. After natural gas pipeline, the burner will automatically supply, cost-effective employee. Gas boilers also need to pay some wages, because they need to participate in coal plan. 3. fuel costs: You can clearly see this by looking at the actual specific fuel prices at each location. The fact is that the amount of coal burned per hour is much higher than the amount of gas. 4. environmental costs: In the need to protect the environment, the review of the gas boiler are becoming increasingly stringent. Because of the economy, environmental protection and energy as well as government policies, gas steam boilers more and more widely used.
Henan reasonable control of gas-fired coal fired boilers pattaya flue gas oxygen content from the actual point of view, in the Henan gas boiler combustion, the oxygen content of the flue gas reasonable control, can also reduce fuel waste to a certain extent. Technology is adding a control loop combustion control system, the main function of this control loop is a variable flow rate and the ratio of the combustion air flow rate control, such a control system, also known as closed loop control system of flue gas oxygen content. By using this control system, making Henan ensure the most economical gas-fired boiler burning throughout the production process. From a practical point of view this stage, the oxygen content is more commonly used in the flue gas. Therefore, it can be said, in Henan gas boiler combustion process by adding a control loop to further improve the reasonable control of the flue gas oxygen content, this method is relatively simple technology, and have a certain economy. Flue gas oxygen content control to the actual operating status of the boiler ignited, under different operating circumstances, to rationalize the ratio of flue gas oxygen content, so that as far as possible both to meet the needs of Henan gas boiler combustion, while there reduce energy consumption. Through the above analysis, we know Henan gas boiler in the actual work process, by controlling the oxygen content of the flue gas in order to achieve energy-saving operation. As people focus on air pollution, the community calls for energy saving technology is growing. In this case, the promotion of energy-saving technologies and upgrading gas boiler, it is very urgent. The relevant state departments should proceed from the actual situation, efforts to promote coal to gas projects, the implementation of the relevant environmental protection policies as soon as possible, give full play to the advantages of gas-fired boiler in terms of energy saving, thus making a contribution to our energy conservation.
When coal-fired coal fired boilers pattayas, four matters requiring special vigilance: the highly polluting coal-fired boilers transformation process, can be said boiler industry mainstream major event. General common is the transformation of coal-fired furnace gas-fired boiler, the coal to change the high fuel costs, as well as on the environment caused serious pollution problem, not a small project, you need to pay attention to the transformation of every aspect of a good safe and effective boiler close with, in order to avoid a failure of the transformation occurred. 1, the original boiler boiler before carrying out the demolition work will require the original host and auxiliary boilers were removed, concrete demolition work carried out by professional staff, in order to more quickly complete the demolition work, but also to prevent the removal process after the accident 2, note that the boiler pressure capacity of some small coal-fired boiler into a gas-fired boiler, also changed the original state of combustion, combustion becomes negative as positive pressure combustion; this process requires special attention throughout the furnace wall the structure and sealing, the sealing function properly may cause the boiler could not withstand the pressure due to the transformation, and accidents. 3, furnace renovation precautions in many cases will change when coal gas, because of poor atomization or incomplete combustion of fuel remaining in the furnace, the slightest mistake will cause fire or explosion; it is to be in the transformation is complete installed in the appropriate parts of the blast doors to prevent the explosion accidents; while additional ignition and flameout protection device to ensure the safe operation of the boiler. 4, after the transformation is complete when the test is completed after the transformation of the boiler, also requires complicated testing to confirm their safety test method is commonly used for the transformation boiler high pressure stress tests, the test and reached after the use of standards, it is considered as completed the transformation boilers.
