[ China Agricultural Machinery Industry News ] On December 4, the National Energy Administration and the Ministry of Environmental Protection issued the "Notice on Carrying out Pilot Work on Coal-fired Coupled Biomass Power Generation Technology Reform" (hereinafter referred to as the "Pilot Notice"), trying to break the direct burning of straw fields. Such as environmental governance problems to reduce the intensity of air pollution in autumn and winter.
The so-called coupled power generation is a mature renewable energy utilization technology. Through the technical transformation of the active coal-fired power units, the power generation system and the environmental protection centralized management platform are used to exhaust the open-air direct-fired straw in the field, and the large-scale synergistic treatment of sludge and garbage. To realize the flexibility of thermal power fuel, reduce the coal consumption of coal and electricity, and increase the power generation of renewable energy. It has the characteristics of low investment, quick effect, low emission and stable renewable energy quality.
"The so-called coupled power generation is what we call co-combustion power generation. This is the renewable energy utilization technology that we have been encouraging and admiring." Qin Shiping, a researcher at the Energy Development and Reform Commission, analyzed the "clean technology investment", and burned coal and forestry waste residue power generation technology. Among the three technologies of the project, the coal-fired coupled waste-to-energy generation and the coal-fired coupled sludge power generation technical transformation project, the technical significance is great.
Qin Shiping emphasized that the problem and challenge of coupled power generation is to solve the problem of scientific and accurate measurement of mixed biomass resource power generation.
Promote large-scale utilization of biomass resources such as straw
Coupling power generation, as a mature renewable energy power generation technology, has formed a large-scale application in the world, and China has just started.
According to the China Biomass Energy Industry Alliance and the Hydropower and Water Conservancy Planning and Design Institute, 11 units jointly issued the “Research Report on Agro-forestry Biomass and Coal-fired Combustion Power Generationâ€. At this stage, the only successful and normal operation in China is Guodian Jingmen Power Generation. The factory's 640MW unit. The biomass fuel mainly used in this project is rice husk, and the biomass treatment capacity of the gasification unit is 8t/h, and the generated gas is 10.8MWh. The on-grid electricity price of the biomass power generation part is 0.75 yuan/kWH, which exceeds the local coal-fired benchmark electricity price and is subsidized by the renewable energy development fund.
To this end, the "Pilot Notice" proposed that the state will carry out a coal-fired coupled agricultural and forestry waste residue power generation technical transformation project, coal-fired coupled waste-to-energy and coal-fired coupled sludge power generation technology transformation project pilot.
Among them, the pilot project of the project attracted people's attention. According to relevant research by the Ministry of Environmental Protection, open burning of straw directly pollutes the atmospheric environment, which has contributed to the formation and aggravation of heavy pollution. Especially in autumn and winter, straw burning, the contribution rate of PM2.5 daily average concentration is between 14% and 55%.
For example, straw burning in some areas of Heilongjiang Province is the “culprit†of heavy pollution in China in the first half of November. On November 28th, the Heilongjiang Provincial Agriculture Committee and the municipal governments of Harbin, Jiamusi, Shuangyashan and Hegang were interviewed by the Ministry of Environmental Protection because of the ineffective management of straw burning.
Chen Guanghui, chairman of the multi-dimensional biotechnology group of Huangshan City, Anhui Province, said that due to policy reasons, China's biomass power generation has long used direct-fired power generation technology. However, due to the small capacity and low parameters, the power generation efficiency of this technology is generally not higher than 25%, and because The economic problems of fuel collection have led to the lack of breakthroughs in technology and the original intention of the straw burning in the field.
"In the world, coal-electricity coupled biomass power generation is a mature technology. With the active large-capacity and rate coal-fired units, the power generation efficiency can reach 40%-46%." Chen Guanghui analyzed that in China, the use of active coal-fired environmental protection centralized management On the platform, the concentration of atmospheric pollutants from biomass power generation can be reduced to one-sixth of biomass direct-fired power generation.
"Coupled power generation can rely on the environmental protection facilities of coal-fired power plants to achieve ultra-low emissions, and promote the stabilization, harmless, energy-based and large-scale utilization of biomass resources such as straw." Qin Shiping analysis.
China has the resource conditions for coal-electricity coupled biomass power generation. About 1.25 billion tons of agricultural and forestry waste residues are produced each year in China. Among them, the amount of crop straw resources available for collection is about 690 million tons. Except for about 350 million tons of fertilizers, feed, base materials and raw materials, about 340 million tons are available for energy utilization. The forestry processing surplus utilized is about 350 million tons.
According to relevant data, after fully meeting the needs of the four industries of fertilizer, feed, base materials and raw materials, biomass direct-fired power generation only consumes about 7% of the total amount of agricultural and forestry waste residues available for energy utilization.
Therefore, from the total amount of biomass resources and the annual increase, coupled power generation will not occupy the raw material space of direct-fired power generation and other four major industrial enterprises, and the resource suppliers will eliminate the major industries including coupled power generation every year. The demand for Na is still very large.
20 companies have submitted pilot applications
According to the “Pilot Noticeâ€, the focus is on 13 major grain producing provinces, giving priority to the selection of cogeneration coal-fired generating units, and laying out a number of coal-fired coupled agricultural and forestry waste residues power generation technical transformation projects.
The requirements of the two departments, in view of the difficulty in straw consumption, the quantity, variety and quality of abandoned forest and forestry residues in severe areas in the field, fully consider the operational safety, load regulation, operational efficiency and economics of the main unit, and tap the heat. The circulation system utilizes the potential of the coupling step to reasonably determine the technical plan of the technical transformation project. The gasification coupling scheme that facilitates the measurement of renewable energy electricity monitoring is preferred.
According to the “Pilot Noticeâ€, the pilot project will be declared by the enterprise itself, and the application report will be reported to the National Energy Administration before January 12, 2018. “The country has not determined the number of pilots, and in principle it is not capped.†An official from the National Energy Administration introduced the “clean technology investment†reporter.
The state requires that the pilot project should establish a resource management account for biomass resources, record the utilization of biomass resources in detail, and adopt a metering device certified by the national compulsory product. The renewable energy electricity meter online operation monitoring value is synchronously transmitted to the power dispatching agency. The data is kept for 10 years.
Qin Shiping analyzed that the requirement of “using a metering device certified by the national compulsory product†is critical, and it can overcome the problem that the utilization of biomass resources that the industry is more worried about may lead to fraud.
“Clean Technology Investment†was informed that up to now, nearly 20 power generation companies have reported to request the pilot work of coupling power generation technology transformation.
