ECOVE Receives Praise from Owner for Upgrading the Efficiency of Kanding Energy-from-Waste Plant

Writtten by: Chen Zun Liang, the Manager of Kanding EfW Plant, Environmental Protection Business Operation Center, Taiwan Sugar Corporation(TSC).

The Kanding Plant is an Energy-from-Waste(EfW) Plant owned by the Kaohsiung City Government and operated by Taisuger, a private company, since 2001. The waste disposal capacity of this plant was designed at 900 tons/day (two 450 tons/day incinerators ). However, the operating efficiency start declining in recent years. The main reason of the declination is due to Auto Shredder Residue (ASR). Since heating value and chloride concentration of ASR are high, it is easily caused high combustion temperature and HCL concentration. Those acid gas will make boiler tube get thinner and tube leakage is often happened not only in boiler but also flue gas channel, which will further affect waste treatment capacity of Kanding EfW Plant. 

TSC is a business in the state-owned enterprise system and therefore is required to follow the government procurement procedures and regulations for maintenance of the major system equipment and procurement of various supplies. This is a time-consuming process and very often the expected goals cannot be achieved in the most time-efficient manner, especially for urgent repairs. Therefore, TPC has to seek a competent technical service supplier to upgrade the equipment and operating environment, in expectation to improve the operating rate and equipment efficiency.

In April 2017, the tender was opened and ECOVE Environment Service Corp. won the bid. This company, a subsidiary of the ECOVE founded in 1994, has over 20 years of experience in maintenance and annual service of incinerators and a strong technical backup from its parent company, CTCI, an expert in incinerator construction. In addition, ECOVE has also assisted TSC in annual service and overhaul projects at the Kanding Incineration Plant. Therefore, TSC believed that the company's professional background and experience will help the Kanding EfW plant to enhance its efficiency.
   
The scope of this project covers an overall upgrade for 16 main equipment including boiler tube renew, grate renew, bag filter, flue gas channel, STG overhaul, DCS system and etc. Compared to the condition before the upgrade, the daily processing volume increased from by nearly 150 tons, and the operating rate was increased from 73.3% to now full capacity. This upgrade has effective relieved the City from the pressure of waste treatment. In this project, ECOVE demonstrated high-level of professionalism and dedication from the initial manpower arrangement and seamless integration of daily operations and maintenance work to introducing patented technology, intelligent systems and equipment evaluation and improvement. It is indeed not an easy task to achieve such a remarkable improvement in just six months. Our on-site staff observed that ECOVE's field staffs were very focused and that is why they were able to improve equipment efficiency in such scale and significantly ahead of the schedule. We are very please with such results and recommend highly of their services.
