On may 26, Changsha city organized related experts to make a mid-term evaluation for significant scientific and technological special project of Changsha city in 2009 undertaken by Zhongye Changtian which took the lead in undertaking the project, the project is about “Reducing flue gas emission and Research, development and industrialization of key technology of desulfurization and denitration----Study on flue gas circulation sintering process and equipment”. After hearing the project report, the expert group agreed to pass the mid-term evaluation.

The project of “Reducing flue gas emission and Research, development and industrialization of key technology of desulfurization and denitration----Study on flue gas circulation sintering process and equipment” includes four sub-projects, that is, study on flue gas circulation sintering process and equipment, research and industrialization of denitration process and equipment with SCR method, research and industrialization of desulfurization process and equipment, research and industrialization of integrated technology of wet type desulfurization and denitration of industrial coalfired boiler flue gas.

This year is the first year for execution of special project, up to the present, all mechanism and laboratory test study have been completed  for one of the sub-projects undertaken by Zhongye Changtian----“study on flue gas circulation sintering process and equipment”, the breakthrough is realized for comprehensive balance technology of flue gas circulation sintering, and such auxiliary equipment as flue gas circulation sealing hood and sinter machine feed end and discharge end sealing device are developed, and the project contract indexes of this year have been overfulfilled.
