If we can implement the "green stove" project like "green lighting", our country can save 73% of the West-East Gas Pipeline output each year. The National Development and Reform Commission recently announced the “National Key Energy Conservation Technology Promotion Directory (Third Batch)â€, which includes a total of 30 energy-efficient technologies in 11 industries including coal, electricity, steel, and transportation, and the formation of shaped combustion technology. The main applications of shaped combustion technology are gas stoves, gas water heaters, domestic heating stoves and other household gas appliance products and equipment, and industrial combustion heating processes in industrial manufacturing. As early as the “Eleventh Five-Year Planâ€, energy efficiency has been listed as the top priority in 15 years. The formation of agglomerated combustion technology as part of the National Catalogue of Key Energy Conservation Technologies has marked the nation’s desire for rapid nationwide promotion. Energy Consumption Forms a Pattern of "One Consumption and Three Longs" The seemingly inconspicuous gas cooker, in fact, consumes an astonishing amount of energy and continues to rise. According to the “Analysis Report on Energy-saving Potential of Low-carbon and Environmentally-friendly Gas Cookers†published by the National Low Carbon Economy Technology Center (hereinafter referred to as the “Reportâ€), the output of the gas stove industry has maintained a momentum of growth since 2004. In the context of the 2008 financial crisis, it also increased by 16.4% over 2007.†Wang Jianfu, Deputy Director of the Low Carbon Economy Technology Center of Guo Ruiwo De (Beijing) believes that in the next few years, the gas cooker industry will maintain about 20% per year. increase. The data from Tsinghua University’s Building Energy Research Center shows that in 2008, the total energy consumption of residents outside China’s heating industry was 307 million tons of standard coal. The total gas consumption of cooking activities was equivalent to 41.27 million tons of standard coal, which accounted for the total energy of civilian use. The consumption of 13.4%, "China's current gas stoves have about 186 million units. With the rapid and steady growth of the national economy, the acceleration of the urbanization process and the gradual development of the rural market, the consumption of cooking gas will further increase." Dai Yande told the “China Economic Weekly†that in the next 10 years, as China’s economic growth rate decreases slightly and the economic structure is adjusted, industrial energy consumption will decline, but the energy consumption of transportation, construction and people’s livelihood will increase rapidly, forming “a In the pattern of eliminating consumption, the annual energy demand may have to increase by 200 million tons of standard coal, and there will be an increase of 2 billion tons of standard coal in the next 10 years.†Dai Yande said, “This is different from the growth in energy demand in the past 10 years. Not only can the environment fail to bear, but more importantly, the supply cannot be met. The total energy consumption must be reduced through energy conservation." Bai Rongchun, chairman of the China Resources Comprehensive Utilization Association’s Energy Resources Comprehensive Utilization Professional Committee, said that according to the plan, China will vigorously develop natural gas, and its demand in the next 10 years will at least double its current level, possibly reaching 300 billion cubic meters. While vigorously developing natural gas, we must attach great importance to the conservation of natural gas. “Because the use of gas in the accident accounts for a large proportion of gas consumption, the use of gas for cooking will play a major role in the work of saving and utilizing natural gas in China.†The cooker is the second largest energy consumer after heating The cooker industry has experienced a transition from coal to gas in our country. In the past 30 years, monocular and double-headed tabletop stoves that can be spotted with fire, poor safety, and all made of cast iron have emerged in an endless stream. stable. However, while gas brings convenience to us, its huge energy consumption not only brings great pressure on the environment, but also brings certain risks to people's health. The "Report" pointed out that in our country, the kitchens in daily life are already the major emitters of carbon, and the cookers have become the largest households in China in terms of energy consumption except for heating. The data shows that on average, each gas stove uses about 20 cubic meters of gas per month, and the country consumes 9.3 tons of gas per day, equivalent to a daily discharge of 134,000 tons of carbon dioxide. In 2004, the “Energy Conservation Medium and Long Term Special Plan†issued by the National Development and Reform Commission proposed that by 2010, the domestic gas stove thermal efficiency should reach 60% to 65%. At present, this goal has not been achieved. In 2008, China released the current product access standards, requiring the embedded gas stove heat efficiency not less than 50%, desktop gas stove with a thermal efficiency of not less than 55%. Even according to this access standard, the results of the spot checks conducted by the General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) from April to September 2010 showed that about 2% of the gas cookers had unsatisfactory thermal efficiency due to excessive heat loss. Wang Jianfu told the “China Economic Weekly†that most existing gas cookers currently on the market have problems such as low combustion efficiency, insufficient gas combustion, and large heat loss, which causes a certain degree of waste in the use of gas. At the same time, harmful substances emitted by gas during incomplete combustion also seriously endanger people's living environment and health. Experts said that although the technology of shaped combustion has entered the “National Catalogue of Important Energy Saving Technologiesâ€, the future of energy-saving cooking appliances is still a long way. “One of the reasons for restricting development is the high processing costs.†"Consumers will calculate such an account, ordinary stove 1,200 yuan, energy-saving stoves to 2400 yuan, to save 20% of the annual gas calculation, also about 200 yuan, more than 6 years to recover costs, and the life of the stove It is also 8 years, so many consumers do not favor energy-saving stoves." Wang Jianfu said. "To achieve a thermal efficiency of 60% is the standard for energy-saving and environmental-friendly cooking appliances that are commonly used in the world. The proportion of gas stoves with a thermal efficiency of more than 60% in China is less than 1%. This situation is nearly 80% of energy-saving gas stoves in Japan, the United States, and other developed countries. Compared with the popularization rate, the gap is far away," said Wang Jianfu. Learn from "green lighting" push "green stove" Experts in the industry have stated that gas energy saving is indeed a promising task. However, due to the lives of ordinary people, energy-saving products must remain basically the same as ordinary products in terms of price, and they can help people save money in the process of use. Otherwise, they will be promoted. There is a "shave a fever" situation. Wang Jianfu told the "China Economic Weekly," that energy-saving products that are considered expensive, is actually a kind of inertial thinking, "The current domestic energy-saving stoves in the area of ​​more representative infrared porous ceramic energy-saving stoves, the price from 200 yuan ~ With a price of RMB 2,000, it is very advantageous in terms of energy saving and cost-effectiveness. It has broken the bottleneck of high cost of energy-saving products in the past, and the average number of toxic and harmful gases has been reduced by more than 80%.†Their “Report†also carried out technical measurement and energy-saving effect analysis for infrared porous ceramic energy-saving stoves. “If 50% of households in the entire society use infrared energy-saving stoves, they can save 77.1 billion yuan in gas costs each year, and they can also save a large number of domestic lacks. Copper material." Liu Yanchun, deputy general manager of Guangzhou Hongri Burning Appliance Co., Ltd., told China Economic Weekly that the infrared flameless combustion technology changed the way ordinary stoves transmit heat through convection and heat conduction. “The thermal efficiency is up to 70.1%.†Together with the use of ceramics instead of copper and other metal materials as key components, the production process itself has reduced emissions, there is no open fire during use, and kitchenware and kitchens are “cleanerâ€. “We need to attach great importance to energy-saving work using energy.†Bai Rongchun told the China Economic Weekly that “use of cooking can account for 13.4% of total civilian energy consumption, while green lighting only accounts for 10% of civilian energy.†Like green lighting, the slogan of 'green cooking appliances' should also be proposed now. At the same time, it should draw on and learn from the practice of implementing the concept of 'green lighting' as soon as possible, formulate energy efficiency standards for gas stoves as soon as possible, and regulate and ensure the right competition in the industry. Provide technical support for the implementation of energy-saving product subsidies."
