The FGC project constructed by Huaxing for Caofeidian waste incineration power plant in Tangshan, Hebei passed 72+24 hours trial operation on June 14, 2022.
The plant has an average waste treatment capacity of 500 t/d, equiped with 1 × 500 t/d mechanical grate + 1 × 10 MW condensate steam turbine generator. The FGC adopted the process of "SNCR with in-furnace ammonia solution injection (not the scope of contract) + semi-dry reaction tower with lime slurry solution (not the scope of contract) + dry method with lime powder (not the scope of contract) + activated carbon injection adsorption (not the scope of contract) + activated carbon injection adsorption (not the scope of contract) + sodium bicarbonate grinding + bag filter (not the scope of contract)+ SGH (steam-gas heat exchange) + SCR with ammonia solution+ Catalyst (MHI)". It is an EPC project of Huaxing.
In view of the newly issued DB13/5325-2021 Standard for “Air Pollution Control on Municipal Waste Incineration” in Hebei Province requires lower pollutants from newly-built waste incinerators; however, Caofeidian incineration plant did not sign the SCR system in time in the initial construction plan. At the stage when the plant is about to be put into production, Huaxing undertook the SCR system for the plant. Therefore, the plant demostrated a very typical construction period in Hebei.
As a domestic professional leading supplier of flue gas cleaning (FGC) system, Huaxing East has provided favorable and guaranteed hardware for the plant to be put into production in a limited period by virtue of its own factory's advantages of step-by-step design, delivery, and installation, as well as the international division of production steps of Mitsubishi Heavy Industries' collaborative design, manufacturing, and inspection. To ensure the FGC for Caofeidian WTE plant is put into operation as scheduled, from the date of entering the site for construction on March 1, 2022, Huaxing successfully completed the delivery objectives in three months with quality and quantity guaranteed ahead of schedule by means of factory integrated production, reasonable delivery plan, inverted schedule, optimized construction organization design, shifting workgroup, cross operation, quality supervision, and safety measures.
Through short-term transformation complying the new Hebei provincial standard, as a microcosm of the improvement of China's air protection & emission control, the SCR project shows the profund accumulation of Huaxing in the supply of SCR and exclusive low-temperature catalyst. In many years of engineering practice, the establishment of multiple self-owned core equipment manufacturing plants is the core guarantee capability of an engineering company for performance, delivery date, quality, and after-sales service. Meanwhile, Huaxing delivered fast SCR and technical transformation services for customers in Shahe, North Zhangjiakou, Weichang, Dingzhou, Baoding, Caofeidian, Luanzhou, Tangshan, Shijiazhuang, etc. within limited time.
Adhering to the belief of "Integrity, Innovation, Professionalism, and Efficiency", Huaxing stuff have always maintained ethics and fulfilled mission. As an advanced enterprise in the field of air governance in the industry, Huaxing East has provided the industry with a successful design template for low-temperature SCR applications since the Nanjing Jiangbei Plant, and is drafting and preparing a low temperature SCR design procedure in the field of waste incineration. Huaxing has been committed to the development and practice of more advanced emission technologies. As an important participant in the industry, Huaxing has accumulated FGC references for more than 200 incineration plants, nearly 500 incineration lines, providing FGC equipment, design, and engineering services. Among them, there are more than 70 incineration plants and more than 100 incineration lines equiped with SCR system.
The achievements of Huaxing East in Hebei Province include Xia Nenxin of Shijiazhuang, Hengshui, Caofeidian, Weichang, Baoding phase I & II, Shunping, Tangshan phase I & II, North Zhangjiakou, Gu'an, Xianghe, Dingzhou, Cangzhou phase I, Shijiazhuang, Anping, luanzhou, Shahe, etc.
