On April 11, the flue gas desulfurization project of new and old kinetic energy conversion 1#3800m3 blast furnace hot blast stove of Laiwu Iron and Steel Co., Ltd. successfully introduced flue gas and started thermal load test. The successful introduction of flue gas thermal test marks the successful completion of the construction period target required by the owner. This is another blast furnace hot blast stove desulfurization project successfully completed after the completion of 2 * 5100m3 blast furnace hot blast stove desulfurization project of Shandong Steel Co., Ltd.

The new and old kinetic energy conversion 1#3800m3 blast furnace hot blast stove flue gas desulfurization project of Shandong Steel Co., Ltd. Lasting 83 days from design to hot test, and the "baking soda dry desulfurization" process was adopted. The emission concentration of SO2 and particulate matter in the treated flue gas reaches ≤ 30mg / Nm3 and ≤ 8mg / Nm3 respectively, which fully realizes the deep purification and treatment of pollutants.

Affected by the new crown pneumonia epidemic, in the early stage of the project construction, the energy saving and environmental protection branch was faced with the situation of tight construction period, heavy tasks, and large site constraints. During the construction period, it encountered unfavorable factors such as epidemic control and control. Under the leadership of the company, all personnel in the project team worked overtime to overcome the difficulties one by one, from design, procurement to construction. The steel structure designed size was optimized to the greatest extent, the equipment was delivered as soon as possible, and the equipment commissioning personnel were in place in time. The construction unit went all out and finally complete the project with quality and quantity, which laid a solid foundation for the subsequent desulfurization project of SDM.
