【SCR- selective catalytic reduction denitration technology】
Technical Features:
1、High denitration efficiency, reaches over 90 %, which satisfies the state’s requirements on environmental protection;
2、Escape rate of exported ammonia is lower than 3ppm, which cannot causes secondary pollution;
3、Conversion from SO2 to SO3 can be effectively restrained (conversion rate<1%), which can avoid the corrosion and the block of air pre-heater;
4、The consumption of reducing agent is low, which has low operation cost;
5、The system has low running resistance, which resistance is less than 1000Pa.
【The Ozone Oxidation of Denitration Technology】
Technical features:
1、Wide range of applications and no any special requirements. It is especially suitable for small flue gas, and to denitrificate under the condition that the NOx initial concentration is not high;
2、Denitrification efficiency is high, which can be up to 90% or more. The most economical denitrification efficiency is controlled at about 60%;
3、There is no need to increase the flue gas temperature, it can be denitrification below 250 ℃;
4、Do not use ammonia and other reductants and ozone is easy to be decomposed. Besides, there is no ozone escaping or secondary pollution and other issues;
5、It is easy to be installed, just shutting down about 3 days, whihc does not affect the production and operation;
6、It also has a certain ability to remove heavy metals within the flue gas.
【Low NOx combustion and optimal transformation of boiler】
AS to CFB, our company mainly has the following several technical routes:
1、Exhaust gas recirculation technology can restrain the generation of NOx;
2、Staging air supply technology:Oxygen optimization and REDOX atmosphere optimization reorganization;
3、Separator reconstruction technology: improve the separation efficiency;

Our company has obtained the prizes of National Torch Plan Key High-Tech Enterprise, China's Environmental Protection Industry Backbone Enterprises, The National Enterprises and Intellectual Property Pilot Units, National Innovative Pilot Enterprises and other several prizes above the provincial level. We lead the head to pass the European CE Authentication and ISO9001, ISO14001, OHSAS18001 three standard Authentications in our industry. Our company believes in "thoughts decides the developing direction, personal personality casts great products" business philosophy, "system first, leaders second" management principles, "resources is limited while science and technology is unlimited" industrial responsibility and "improving technology level, being industry model" development goals and other core company cultures in order to form a team common value. We have a huge influence in the society and will precipitate the characteristics as our corporate culture strategy.
In the area of scientific and technological innovation, the Company has participated in and undertook 8 provincial scientific research projects, two big scientific and technological achievements transformation projects of Jiangsu Province, one national science and technology support plan, one national "863" project, and three Innovation Fund Projects of the Ministry of Science and Technology, two National Torch Plans, six national key new products, four national environmental protection authentication products, two national "13th Five-year Plan" key research and development programs, achieved 17 provincial high-tech products, 8 provincial and municipal scientific and technological progress awards, presided over or participated in 21 revisions of industry standards, and established more than 20 enterprise standards. The company also carried out pragmatic cooperation in the respect of production and research with Tsinghua University, Beihang University, Zhejiang University, NCEPU, Southeast University and several foreign well-known environmental agencies & research institutes.
In terms of service quality, the company creates a series of high-quality projects with the "four fine" quality policy i.e. "well design, lean manufacturing, boutique marketing, sincere service", three-graded quality assurance system, whole tracking service mechanism. Meanwhile, we also obtained the prizes of "Quality Award of Jiangsu Province" and "Quality Advanced Unit in Jiangsu Province". The advantages including the personalized service, international positioning and large-scale development make the company obtain a rich experience in the projects implementation and EPC general contracting capacity, and we have established a long-term cooperative relationship with Huaneng, Guodian, Datang, Shenhua, Sinopec, PetroChina, CNOOC, China Aluminum, China Coal, Everbright International, Mona Lisa, the new pearl, China Building Materials, Jinyu and other industry leaders. The products are exported to more than 20 countries including Denmark, Russia, Turkey, Vietnam, Nigeria and Indonesia. As the first-top brand in the field of flue gas treatment in domestic industry, the company has accumulatively contracted a total of more than 200 dust desulfurization and denitration ultra-low emission demonstration projects.
Cohen People with uprightness, passion, innovation and cooperation always adhere to the operation principle of Thoughts Decides the Outlet, Personal Personality Casts Great Product, will insist on the development idea of Personality Culture and Quality Engineering, dare to make creation, have the courage to bring forth the new ideas, is good at cooperation and constantly build enterprise’s comprehensive competitiveness in order to make contribution to mankind environmental protection career.
