High Pressure Vertical Centrifugal Induced Draft Blower Fan Furnace Dedicated

DINKONDA GLOBAL Power Plants Special Y9-19/Y9-26 Series High Resistance Vertical Furnace Dedicated High-pressure Output Induced Draft Fan

Product Overview
Y9-19 and Y9-26 type vertical furnace dedicated induced draft fans are developed for actual working conditions of vertical furnaces. A special optimization design is carried out to address the problems of large fluctuations in coal quality on site, increased system resistance due to the installation of dust removal equipment and waste heat utilization equipment, and insufficient fan suction force, resulting in the inability of the furnace to operate normally. This effectively solves the problem of insufficient ventilation caused by increased system resistance, provides sufficient negative pressure for the vertical furnace system, and ensures the continuous and stable operation of the entire process. It is suitable for extracting flue gas from metallurgical vertical furnaces and similar high resistance industrial furnaces.

Structural Composition
1. Shell: Steel plate welded thickened snail shell structure, with high overall rigidity and resistance to high temperature, dust and smoke erosion and wear. The shell is equipped with maintenance ports for easy internal dust cleaning and impeller inspection.

2. Impeller: It adopts a high-strength forward blade structure and is made of wear-resistant steel plates. The impeller has undergone strict dynamic balance verification and can operate continuously for a long time under high negative pressure and dusty flue gas conditions, with strong resistance to dust erosion.

3. Inlet: Convergent streamlined inlet reduces intake vortex loss, enhances fan pressure output capacity, and meets the requirements of high resistance system operating conditions.

4. Transmission components: High quality alloy steel main shaft is selected, matched with reinforced high-temperature resistant bearing box, coupling direct transmission, high transmission torque, stable and reliable operation.

5. Base: Steel welded integrated base, with integrated installation of fan host and motor. The base has strong rigidity, suppresses operational vibration, and facilitates on-site positioning and alignment.

Core Features
1. Strong high-voltage output capability: specifically designed for the increased system resistance caused by dust removal and waste heat recovery equipment, solving the problem of insufficient system suction force and ensuring stable negative pressure in the vertical furnace.

2. Strong adaptability to working conditions: It can adapt to production conditions with large fluctuations in coal quality, and can maintain stable pumping force even when the system resistance changes, ensuring normal process operation of the furnace.

3. Wear resistant and high temperature resistant: The impeller and casing are strengthened for the treatment of dusty and high-temperature flue gas, suitable for continuous production conditions in vertical furnaces, and the equipment has a long service life.

4. Stable and reliable operation: high-precision dynamic balance correction of the impeller, low vibration amplitude of the whole machine, can meet 24-hour uninterrupted operation in industrial sites.

5. Easy maintenance: The casing is equipped with a reserved maintenance window, which allows for easy cleaning of dust accumulation on the impeller. The disassembly and maintenance of bearings are simple, reducing maintenance costs.

6. Flexible selection: Multiple machine numbers are available, and the rotation direction and air outlet angle can be customized according to the on-site pipeline requirements.
