Energy supply is one of the primary building blocks of our society. Worldwide, and especially in
rapidly developing countries, e.g. China and India, the demands of energy for housing, industry,
transportation and communication are constantly increasing [83]. The global energy supply is
currently dominated by combustion of fossil fuels. In 2008, 85.1% of the global primary energy
supply was produced from the combustion of oil (34.6%), coal (28.4%) and natural gas (22.1%).
From the 12.4% of renewable energy sources, 82% (in total 10.2%) was bioenergy based on
burning renewable rescources [45]. Recent reports confirm that a dramatic shift towards CO2
neutral energy supply is required to stop the current trend of global warming [135]. Nevertheless,
the slow developement of renewable energies over the last decades as well as the absence of
large technological advancements in nuclear fusion technology indicate that this structure will
not substantially change in the coming decades.
Besides emissions of CO2, further pollutants are formed during the combustion of fossil or
biofuels. From these emissions, nitric oxides (NOx) have been identified as a major problem
of practical combustion processes [214]. In the recent decades nitric oxides became a significant
contributor to photochemical smog and ozone in urban air [180]. It further participates
in the chain reaction removing ozone form the stratosphere with the consequence of increased
ultraviolet radiation reaching earths surface [90]. NOx is generally formed during the oxidation
process of nitrogen containing fuels such as coal and oil. However, the gross NOx emissions
are created at high combustion temperatures from nitrogen in the air. These are typical for hard
coal plants, internal combustion engines and gas turbines. Hence, it is essential to understand
the physico-chemical processes of NOx formation and concepts to reduce or even eliminate NOx
emissions. 德國(guó)LaVision PIV/PLIF粒子成像測(cè)速場(chǎng)儀 自適應(yīng)粒子成像測(cè)速場(chǎng)儀(PIV) 時(shí)間分辨粒子成像測(cè)速系統(tǒng)(TR-PIV) 三維立體PIV PLIF平面激光誘導(dǎo)熒光火焰燃燒檢測(cè)系統(tǒng) 時(shí)間分辨平面激光誘導(dǎo)熒光測(cè)量系統(tǒng)
