Jiangsu Huaxing East Environmental Protection Technology Co., Ltd.

The Small-scale Grate and FGC system of Zhuozi MSW Incineration Power Generation Plant in Ulanqab, Inner Mongolia, undertaken by HEPT, has commenced construction since June 28th., 2024. This project represents not only another masterpiece of HEPT's dedicated cultivation in the environmental protection sector but also a significant breakthrough in small-scale waste incineration technology application, bearing exemplary demonstration significance.

The project has a total capacity of 75 tons of MSW incineration treatment per day, adopting a small-scale 1×75t/d reciprocating mechanical grate furnace with FGC system utilizing the "SNCR + Semi-Dry Spray + BHF + SCR" treatment process, with equipment all supplied by HEPT.

In active response to national policy calls encouraging the development of small-scale waste incineration technology in county-level regions, HEPT has keenly captured market demands and leveraging profound technical accumulation and rich industry experience, devoted full efforts to the R&D and manufacturing of small-scale waste incineration grate furnaces. This small-scale grate furnace applied in the Zhuozi WtE plant is the result of HEPT's joint R&D with industry partners based on industry technology exploration and market demand research. Through modular design and process optimization, a solution compliant with domestic environmental standards and regional disposal requirements has been formed, embodying the practical value of industry technology collaborative innovation.

From a design concept perspective, it fully considers the characteristics of relatively small and dispersed waste generation in county-level regions, with miniaturization as its core advantage for precision development. Its compact structural design significantly saves land occupation, making it undoubtedly the optimal choice for county-level regions with relatively tight land resources. Even within limited site space, it can easily achieve efficient and stable operation, providing convenient and feasible solutions for local waste treatment.

In terms of technical performance, this small grate furnace possesses excellent combustion efficiency. Through unique reciprocating mechanical motion design, it enables waste to fully tumble and stir on the grate, achieving uniform combustion and ensuring complete decomposition and conversion of organic matter in waste, minimizing the generation of dioxins and other harmful substances. Meanwhile, the advanced combustion control system can real-time precisely adjust combustion parameters according to waste calorific value, moisture content, and other characteristics, ensuring combustion process stability and efficiency, effectively improving energy utilization rate, and achieving waste treatment reduction, harmlessness, and resource utilization.

The small-scale 1×75t/d reciprocating mechanical grate furnace planned for the Zhuozi MSW Incineration Power Generation Project in Ulanqab was designed with full consideration of the special needs of small-scale application scenarios during the design phase. The design team created a small grate furnace with efficient combustion performance, convenient later maintenance, and good adaptability to different waste components, fully satisfying local domestic waste treatment needs in terms of technical reliability, economic rationality, and environmental friendliness. It not only provides reliable technical guarantee for local MSW treatment but also establishes a classic example for HEPT in the small-scale waste incineration grate field.

Over the past 4-5 years, HEPT has completed a strategic leap from one FGC system to dual-core coordinated development of "Flue Gas Treatment + Core Equipment Manufacturing," relying on keen market insight and powerful technical integration capabilities. Building upon process advantages and engineering experience accumulated in FGC system field, HEPT has gradually extended upstream in the solid waste incineration industry chain. In the equipment manufacturing sector, HEPT has successively completed customized grate production tasks for Vølund, Mitsubishi, Dyna-green, Ebara, LAWI and others, successfully achieving large-scale implementation of incineration grate manufacturing OEM business. From precision component processing to complete furnace system integration, it has constructed a full-chain manufacturing system covering design, process and quality control. HEPT has also deeply participated in equipment upgrade and transformation for over twenty incineration projects including Shanghai Jiading, Guangyuan, Huiyang, Fengcheng, Anshun, Jinzhou and Wuzhong, forming a full-cycle maintenance service system covering equipment overhaul, system optimization and intelligent operation & maintenance, having completed maintenance and servicing tasks for over 100 sets of core equipment.

Through the dual-wheel drive of manufacturing OEM and operation & maintenance services, HEPT has established a manufacturing base with annual production capacity of 500 sets of incineration core equipment and built a global service network covering Southeast Asia and Northeast Asia. From specializing in FGC system to leader in solid waste incineration equipment manufacturing, HEPT has been using technological innovation as its engine to continuously deepen the localization substitution process for key equipment including incineration grates and water-cooled systems, steadily advancing toward the strategic goal of becoming a "Leading Enterprise in Solid Waste Incineration Equipment Manufacturing."

To date, HEPT has successfully implemented multiple benchmark grate, FGC system and supporting facility projects globally, covering locations including overseas, Issyk-Kul in Kyrgyzstan, Maha Sarakham, Sa Kaeo, Chainat, Chumphon, Ratchaburi and Rayong in Thailand, Spain, Norway and Indonesia projects with GEA, Palembang Indonesia, TK, IKSI, Thai Binh Vietnam, Selangor Malaysia, Hyderabad, Pune and Dundigal in India, Varaka in Turkey, West Nagasaki in Japan as well as domestic locations including Nanhai in Foshan Guangdong, Zhuozi in Inner Mongolia, Changning in Hunan and Guangyuan in Sichuan. HEPT has cumulatively participated in over 300 global solid waste incineration plants, with more than 500 sets of FGC systems already in operation or completed, spanning 31 regions domestically and internationally.
