The ignition of Gasification Unit B was carried out for Zhejiang Jinju’s 39,000 Nm3 air separation plant renovation project. On January 1, 2023, at 5:48 a.m., the Gasification Unit B of Zhejiang Jinju Chemical Co., Ltd.’s ammonia synthesis feedstock route and energy-saving/emission-reduction technology renovation project was successfully ignited after passing the commissioning tests. The synthetic ammonia feedstock route and energy-saving and emission-reduction technology renovation project of Zhejiang Jinju Chemical Co., Ltd. utilizes the water-cooled wall waste-heat gasifier (Jinhua Furnace 3.0) manufactured by Lu’an Chemical Machinery (Group) Co., Ltd. The gasification unit is designed as a dual-unit setup; each gasifier weighs 260 tons, is 19.042 meters in height, and 4.024 meters in diameter, with a total gas production capacity of 94,000 m3/h (CO + H2). Vaporization pressure is 6.5 MPaG, and the total gas volume is 94,000 Nm3/h (CO+H2). The water-cooled wall direct-connected waste-heat boiler gasifier (Jinhua Furnace 3.0) for coal-water slurry replaces the existing batch fixed-bed gasifiers and low-pressure refractory brick quenched gasifiers, achieving an annual production capacity of 350,000 tons of ammonia.
