​High-Temperature Centrifugal Fan Product Introduction

High-Temperature Centrifugal Fan Product IntroductionFeaturing a newly designed high-temperature centrifugal fan that meets the "three-way" standard. This centrifugal fan is widely used in China's manufacturing industry. Its primary structural feature includes two rows of widely spaced air outlets, with bottom coke combustion forming two independent combustion zones. By extending the superheating zone, it increases the superheating distance for molten iron and intensifies bottom coke combustion. This ensures stable furnace conditions, high molten iron temperature, and superior iron quality. Based on air supply temperature, high-temperature centrifugal fans are categorized into two structures: furnace shell internal cooling air and hot air. Different air supply temperatures meet diverse smelting requirements. High-temperature centrifugal fans utilize a close-ribbed furnace shell heat exchanger to convert physical heat from furnace gases into cooling air. Operating at temperatures several hundred degrees Celsius, they feature compact structure, convenient operation, low thermal inertia, and no occupation of workshop production space. High-temperature centrifugal fans are widely used in wastewater treatment, blast furnace smelting, coal preparation plants, mineral flotation, chemical gasification, vacuum systems, and other fields, and can also transport other special gases. Construction and Working Principle of High-Pressure Centrifugal Blowers Construction of High-Pressure Centrifugal Blowers High-pressure centrifugal blowers generally consist of an inlet, impeller, volute casing, and guide vanes. Structure of High-Pressure Centrifugal Blowers The impeller is the component that interacts with the air. It comprises a hyperbolic front disc, a flat rear disc, a hub sandwiched between them, and blades fixed to the hub. Air flows along the blades within the impeller. At the impeller outlet, the direction of the relative air velocity W2 forms an angle with the tangential velocity, known as the blade outlet angle. This angle, denoted as β2, determines the airflow characteristics. High-pressure centrifugal blowers predominantly feature backward-curved blades. Two inlet configurations exist: single-suction and double-suction. Under equivalent operating conditions, the blade width (impeller) of a high-pressure centrifugal blower is twice that of a single-suction blower. A guide vane assembly (omitted in some ventilators) is installed between the inlet and impeller to pre-swirl the airflow entering the impeller, thereby achieving performance regulation.
