03.05.2021. Tangshan Ganglu Iron & Steel Co., Ltd., Hebei, China, has commissioned SMS group to supply two wet electrostatic precipitators for two BOF converters. The wet electrostatic precipitators (WESP) supplement the gas cleaning plants of the 180-ton BOF converters. Each of the BOF converters has a gas volume of approximately 216,000 m³/h.

The wet electrostatic precipitators enable compliance with the most stringent environmental protection requirements. Commissioning is scheduled for summer 2021.

Scope of supply

The scope of supply of SMS group as engineering, procurement and construction contractor (EPC) comprises two wet electrostatic precipitators, the adaptation of the water supply and treatment system, erection/installation and technical support during the commissioning process.

Wet electrostatic precipitators separate solid particles from the process gas. For this purpose, spray electrodes fed with rectified negative high voltage emit electrons. These electrons move to the collecting electrodes and, on their way, collide with gas molecules and dust particles. Due to the resulting attachment of the electrons to the dust particles, the particles are negatively charged and transported by the existing electric field to the grounded collecting electrodes to which they adhere. The collecting electrodes are cleaned with water.

At the integrated steel plant of Tangshan Ganglu in Tangshan (Hebei Province) in the north of the People’s Republic of China, long products are produced for a wide range of applications.
