HEPT Commences Construction of Grate Manufacturing + Flue-Gas Cleaning System for Palembang WTE Plant, Indonesia
2025.11.19
The grate manufacturing and flue-gas cleaning package for the Palembang municipal solid-waste-to-energy (WTE) project in Indonesia, undertaken by HEPT, officially broke ground on 5th. August 2025.
Initiated under Indonesia's 2018 Presidential Decree, the Palembang WTE plant is the first waste-incineration power project to start construction under that mandate. Designed to incinerate 1,000 tonnes of domestic waste per day, the plant is configured with 2 × 500 t/d mechanical grate furnaces and 1 × 20 MW condensing steam-turbine generator. The flue-gas cleaning train—supplied by HEPT—adopts "SNCR in-furnace de-NOx (urea) + semi-dry [Ca(OH)? slurry] + dry [Ca(OH)?] + activated-carbon injection + bag filter + fly-ash conveying, storage & stabilisation". Upon completion, the project will markedly relieve landfill pressure in Palembang and deliver over 130 GWh of grid electricity annually, setting a benchmark for waste management, environmental protection and resource recovery in the region.
The grate furnaces employ Denmark's V?lund air-cooled grate technology, supplied by CSET and manufactured by Huaxing Dongfang. From meticulous design by our engineers to high-efficiency operation on modern production lines—precise cutting, grinding and forming of every grate component; from incoming-material inspection to part machining, final assembly and commissioning—each step follows international advanced manufacturing standards, reflecting the wisdom and dedication of Huaxing Dongfang staff. This relentless pursuit of excellence ensures every grate achieves optimal performance, providing a solid guarantee for stable operation of the Palembang WTE plant.

We continuously introduce and absorb international advanced technologies, integrating them into our R&D and manufacturing systems to enhance development and production capabilities. For precision machining of grate components, the company is equipped with full CNC lathes and possesses secondary deep-development ability.
Production bases under HEPT are rationally allocated; an integrated control & commissioning platform in Wuxi plant can perform full-link debugging for 1,200 t/d grate lines.
Upholding the philosophy of "Technology Priority, Quality First ", HEPT actively cooperates worldwide and expands overseas markets. Currently, multiple grate, flue-gas and auxiliary-equipment manufacturing projects have been implemented in Mahasarakham (Thailand), Palembang (Indonesia), Sa Kaeo (Thailand), Chai Nat (Thailand), Nanhai-Foshan (Canton), Zhuozi (Inner Mongolia), Changning (Hunan), Guangyuan (Sichuan), and other regions.
Relying on strong production capacity and technological advantages, HEPT is strategically laying out its global footprint, creating benchmark green-energy projects and contributing HEPT's wisdom and strength to the development of environmental protection worldwide.
