DINKONDA GLOBAL Power Plants Special Coal-fired And Biomass Heating Boilers, Centrifugal High-temperature Induced Draft Fan, Y5-47 Boiler Induced Draft Fan

Product Overview

The Y5-47 boiler induced draft fan is a centrifugal induced draft equipment specially developed by Zhoukou General Blower Co., Ltd. for small and medium-sized coal-fired and biomass heating boilers. It belongs to the special high-temperature induced draft fan for boiler matching. This fan is suitable for chain furnaces, reciprocating grate furnaces, and small circulating fluidized bed boilers. It is mainly used to extract high-temperature dusty flue gas after boiler combustion, maintain stable negative pressure in the furnace, and ensure smooth combustion conditions of the boiler. The product performance curve matches the smoke emission requirements of small and medium-sized boilers, and the structure takes into account high temperature resistance and dust erosion resistance. It is the mainstream induced draft auxiliary equipment for self owned boiler rooms in heating, light industry, and chemical industry.

Structural Composition

1. * * Spiral shell host**
The overall use of high-quality steel plate welded snail shell, with strong shell stiffness; Wear resistant lining plates can be installed on the inner wall of the snail shell to resist the erosion of dust particles in the flue gas; The air outlet is a square flange structure, and the air inlet is a circular flange. Eight installation angles can be adjusted at 45 ° intervals according to the on-site pipeline layout to adapt to different boiler room pipeline directions. Reserved maintenance port on the shell for easy inspection of dust accumulation and wear on the impeller.

2. * * Impeller components**
The impeller adopts rear inclined plate blades and is made of heat-resistant carbon steel. After strict dynamic balance correction, the operating vibration is small; The blade shape has been optimized for fluid flow, resulting in low flow resistance and minimal loss when flue gas passes through. It balances efficiency and wear resistance, making it suitable for long-term transportation of high-temperature flue gas.

3. * * Transmission and Bearing Box**
Adopting a cantilever structure, equipped with an independent bearing box, and lubricated with high-temperature resistant grease/oil; The bearing box is equipped with a heat dissipation structure, which controls the temperature rise of the bearing under high temperature flue gas radiation; The transmission method is divided into two forms: belt transmission and direct coupling, which can be selected according to needs.

4. * * Base and supporting accessories**
Supporting steel welded base with good stability; Optional imported air dampers, shock absorbers, flexible expansion joints, temperature measuring components, mufflers, dust removal matching interfaces, etc.

Product Features

1 * * High temperature resistant design, suitable for flue gas conditions**
The maximum temperature allowed for the conveying medium can reach 250 ℃, and insulation optimization has been carried out for boiler exhaust conditions to reduce heat conduction to the bearing parts, making it suitable for continuous and uninterrupted operation.

2 * * Good resistance to dust accumulation and wear resistance**
The backward inclined blade structure is less prone to dust accumulation and coking, reducing vibration faults caused by imbalanced dust accumulation in the impeller; Wear resistant protective parts can be installed on parts that are prone to wear, extending the service life of the equipment and reducing frequent shutdowns for cleaning and maintenance.

3 * * Flexible working condition adjustment, suitable for boiler variable load**
The performance curve is smooth, and the boiler can operate stably in both low load and high load ranges; It can be adjusted by importing air dampers or variable frequency speed regulation to precisely control the negative pressure of the furnace and adapt to the peak shaving needs of the boiler.

4 * * Strong installation adaptability**
The angle of the air outlet can be adjusted in multiple directions, and the flexibility of on-site pipeline layout is high, reducing the cost of pipeline renovation; Mature structure, convenient disassembly and maintenance, and strong universality in the spare parts market.

5 * * Low operating noise and excellent vibration control**
High precision dynamic balancing of the impeller and optimization of the air duct flow field result in better vibration and noise indicators compared to old-fashioned induced draft fans of the same specifications, making it easier to reduce noise in the machine room.
