Lately, A New Type of High Temperature Air Preheater declared by Shandong Nicest Carbon Black Co., Ltd. obtained the patent for invention granted by the State Intellectual Property Office, which marked the company's technology R&D is pushed to a new level.

The invention is suitable for preheating plant air in the production process of furnace black. In the carbon black production process, utilize the high temperature flue gas generated in the production of carbon black for heat exchange with air required by reaction of generating carbon black in the air preheater, and the preheated air enters the reaction furnace for the combustion reaction, which can reduce energy consumption, improve the quality and yield of carbon black.
