China is a huge coal consumption country, coal consumption is 75% of the one-off energy consumption of the whole country, and 70% to 85% of it is being used in power plants. The directly fired coal exhaust contains a lot of SO2, NOx and Soot, which causes serious fuliginous pollution, results in an annual economic lose of over RMB110billion. China’s government and people have paid much attention to this problem; the General National Environmental Bureau has established Standards of Power Plant Exhaust and the Regulations of the Technology of FGD to control the pollution of the exhaust of power plants. The common means of protection is Flue Gas Desulfurization, FGD in abbreviation, in China now; and the most popular method is Wet Limestone FGD. Various corrosions will occur on the chimney linings as the temperature by this means is usually below the vitriolic dew point. So, corrosion protection has to be done for the power plant chimney in China
According to the official static, there have been power plants totally with a capability of approximately 62,000MW being built or run from 2004 to 2005, which will be more up to 4760,000MW in 2010, then more up to 6000,000MW in 2020. Calculated with a common standard in China now, there are at least 1000 chimneys with more than 8 million m2 needing corrosion protection in China’s market.
In fact, materials like glass-flake, nickel-alloy and rubber are being used now, but they are not very challengeable in marketing because of various reasons. For example, nickel-alloy is a kind of good material, but its price is far beyond China’s market demand. So, there is a large gap of technology and materials to meet the developing demand of China’s chimney corrosion protection market. In this case, a golden chance is ahead of our products with excellent quality, reasonable price and perfect service, which will make us winner of this tremendous market. |
