The Jinhua Furnace 3.0 in Xinjiang Tianye’s ethylene glycol production project achieved continuous high-level operation for 130 days, setting another record. Author/Source: Jinhua Furnace; Date: 12-14-2021; Clicks: 8. On December 14th, the No. 2 gasification furnace (Jinhua Furnace 3.0) part of Xinjiang Tianye Group Co., Ltd.’s plant with an annual production capacity of 600,000 tons of ethylene glycol, operated at a high level continuously for 130 days, breaking the previous record held by Furnace No. 3, which had operated for 111 days. This marks yet another new world record for such gasification furnaces. This achievement represents an important milestone in the field of large-scale water-coal slurry gasification technology worldwide, signaling another major step forward for the domestically developed \"Jinhua Furnace 3.0\" gasification technology on its path to becoming internationally leading. Tianye Group’s project for producing 600,000 tons of ethylene glycol per year utilizes the \"Jinhua Furnace 3.0\" gasification technology; each furnace consumes approximately 1,500 tons of coal per day, operates at a pressure of 6.5 Mpa, and represents an efficient combination of \"coal slurry + water-cooled walls + radiant steam generators\". To ensure the optimal performance of the “Jinhua Furnace 3.0” unit, a coal blending database was established to **enhance the gasifier’s adaptability to various coal types**, thereby enabling reliable switching and stable operation with three units in service and one on standby. It breaks the foreign monopoly on waste heat recovery technology for syngas in water-coal slurry gasifiers, and represents a state-of-the-art, environmentally friendly and efficient gasification unit in the industry today. Project Overview: Xinjiang Tianye Huihe New Materials Co., Ltd. operates in the Shihu Tan New Materials Industrial Park (Group 147) in Shihezi City, Xinjiang, using local coal from Xinjiang as raw material to produce ethylene glycol. There are a total of four sets of 6.5MPa Jinhua furnace 3.0 gasification units, operating in a three-in-one-backup configuration; each furnace produces 100,000 Nm3/h of useful gas (CO+H2). The waste heat from the gasification furnaces generates 9.8MPa G saturated steam, which is fed into the pipeline network. Construction began in August 2017, and the project was completed with construction and commissioning finished in July 2020, meeting the conditions for starting up chemical production. The Jinhua Furnace 3.0 gasification unit was successfully ignited on July 28, and coal water slurry was fed successfully on July 29, resulting in the production of effective gases (CO+H2).
