A few days ago, Mao Jianxiong, professor of thermal engineering at Tsinghua University, predicted at the 15th Clean Coal Forum that for a long time in the future, the status of coal power as the main body of China's power is difficult to change, and by 2030, China's installed coal power capacity will reach more than 1.
4 billion kilowatts, accounting for 56.
2%
of the installed power generation capacity.
In the case of increasingly stringent environmental protection requirements and the long-term need for coal power, the most realistic and effective way to reduce carbon dioxide emissions from coal power is to improve power generation efficiency, through supercritical and ultra-supercritical and co-fired biomass technology
.
From a foreign point of view, the technology of mixing 10% biomass in large-capacity ultra-supercritical pulverized coal furnace power plants has a lot of practical experience
in EU countries.
For example, all coal-fired power plants in the UK are coal and biomass co-burning, and 5% to 10% biomass co-firing
can be achieved due to support policies in place.
However, China does not have relevant policies, so the most practical approach at present is to develop new low-energy technologies based on supercritical and ultra-supercritical power generation technologies
as much as possible.
At present, China's clean coal power generation efficiency has been greatly improved, and the carbon dioxide emissions of ultra-supercritical units have been reduced to 70%.
Supercritical and ultra-supercritical units with large capacity and high efficiency have become the main units of thermal power in China, and their number of units and installed capacity are the first
in the world.
At the end of 2014, nearly 100 1,000 MW ultra-supercritical units were put into operation in China
.
Strict coal-fired thermal power emission standards are a huge driving force for controlling thermal power pollutant emissions, and technological innovation is the key
to achieving high efficiency and low emissions of coal-fired thermal power units.
