After ten years of development, desulfurization and denitrification market has become relatively mature in China. Some small and strength-lacking enterprises have been eliminated after several round of industry reshuffle; the manufacturers taking part in the present competition are relatively stable, but the industry overall profit margins is low. With the completion of desulfurization project and the decrease of newly built projects, thermal power desulphurization market shows shrinking trend. Due to the thermal power plant construction slowdown and tightened emissions standards, the competition focus in desulfurization market is transferring from newly-built projects to desulfurization facilities upgrading.
Impacted by thermal power installed capacity, desulfurization market hovered around the high level in 2006-2008; while a significant decline showed up in 2009. According to China Electricity Council statistics, the annual contract capacity of desulphurization enterprises was only 41 million kilowatts in 2011. The newly built units had little difference in 2012 and 2011; the annual contract capacity was about 50 million kilowatts. In 2012, desulfurization facilities renovation project in thermal power industry open tendering was 30 million kilowatts, approximately accounting for 6% of the total capacity of the unit in operation. The market capacity of desulfurization renovation is gradually surpassing that of newly-built units.
Electricity power denitrification has become the focus of emission reduction. Ministry of Environment Protection officially released the new “Thermal Power Plant Air Pollutant Emission Standards”; the nitrogen oxides emissions for the first time has been included in the mandatory standards; the nitrogen oxide emissions of coal-fired boilers is limited below 100mg/m3 which is the world's most stringent denitrification standard. The State Council issued the “‘12th Five-Year’ Energy Conservation and Emission Reduction Comprehensive Work Program” in which national total emissions of nitrogen oxides will be controlled at 20.462 million tons, obtaining a decrease of 10% over 2010. With the introduction of the “12th Five-Year Plan” and the possible introduction of denitration electricity price, the electricity power denitrification market, driven by policy, is expected to be in prosperity in the “12th Five-Year” period.
The popularizing rate of denitration equipment is low, and the market potential capacity is hundreds of billions. While the popularizing rate of electricity power desulphurization facilities surpassed 80%. By the end of 2010, among the 707 million of thermal power installed capacity, only 218 units of coal-fired units are installed with denitration equipment; the total capacity is about 97 million kilowatts, and the popularizing rate is only 13.7%.
The popularizing rate of denitration equipment is low, which shows that under the circumstance of low benefit in power generation, thermal power plants lack the motivation of active participation in the denitration investment, as well as electricity power denitration engineering market is full of opportunity; once the policy is in place, the denitration market in short-term is expected to show the boom that appeared in desulfurization market during “Eleventh Five-Year” period.
