- Lime powder system
- By-product Storage System for Desulfurization Gypsum
- Coal Transfer and Supply System
- Temporary Storage and Treatment Warehouse for Slag
1. Fly ash collection and storage system
During the operation of coal-fired boilers, a large amount of fly ash is produced in the flue gas. The traditional method of piling up fly ash is prone to secondary pollution and resource waste.
AGICO SOLUTION:
- Airtight design, intelligent unloading system.
- Ensure stable discharge and efficient recovery of fly ash, facilitating the commercial reuse of fly ash.
AGICO SUPPLY:
- A medium-pressure pneumatic conveying system is matched to achieve closed automatic conveying from the electrostatic precipitator to the silo.
- Technologies such as fluidized discharge, gasification pipes, and vibration to break arches are configured to prevent fly ash bridging and material blockage.
- A pulse dust collector is also provided to ensure no dust emission from the silo top.
2. Lime powder storage and transportation system
The flue gas desulfurization system requires a large amount of lime powder as a reactant. Its storage and transportation system must ensure that the material is dry, sealed, and explosion-proof.
AGICO SOLUTION:
- Highly customized design, adapted to the physical properties of the powder.
- Meeting the strict requirements of the desulfurization system for material cleanliness and continuous supply.
AGICO SUPPLY:
- The silos are internally coated and fitted with anti-bridging equipment to prevent the lime powder from absorbing moisture and clumping.
- They can be seamlessly connected with screw conveyors and pneumatic conveying systems for automatic feeding.
- We also provide powder material measurement, storage position alarm, and remote management functions.
3. By-product Storage System for Desulfurization Gypsum
A large amount of desulfurization gypsum is produced after limestone-gypsum desulfurization and needs to be stored before being transported to building material factories or brick factories for reuse.
AGICO SOLUTION:
- AGICO’s advantages: The storage bin structure is anti-condensation and anti-corrosion, thereby extending the bin’s service life.
- The efficient automatic unloading system is suitable for large-scale transportation.
AGICO SUPPLY:
- Adopt moisture-proof large-capacity steel silos.
- With a cone bottom design and a wet discharge device to prevent gypsum from caking.
- Support multiple discharge methods such as truck bulk loading and belt conveying.
- It can be integrated with a stacker-reclaimer system to achieve warehouse automation management.
4. Coal Transfer and Supply System
Large thermal power plants receive coal by train or ship and need to set up coal bunkers for transfer to ensure a continuous coal supply and reduce the area of the coal yard.
AGICO SOLUTION:
- High-efficiency automatic coal discharge， intelligent coal type switching.
- Effectively improving coal supply efficiency and reducing energy consumption.
AGICO SUPPLY:
- Design an anti-pressure steel plate coal bunker with impact resistance and wear resistance.
- Equipped with a gravity discharge, coal gate, and belt conveyor to achieve continuous automatic coal supply.
- Multiple coal-type separate bins can be set up to utilize mixed coal of varying qualities.
- Integrate temperature measurement, position measurement, and dust suppression systems.
5. Temporary Storage and Treatment Warehouse for Slag
The by-products, such as bottom ash and slag from the boiler, need to be temporarily stored to prevent excessive accumulation or airborne pollution.
AGICO SOLUTION:
Specifically designed to ensure on-site safety and optimize environmental indicators.
AGICO SUPPLY:
- Build a corrosion-resistant steel plate slag storage bin with a strong dehumidification design.
- Equipped with a screw slag discharge device and a vehicle-mounted unloading system for flexible transportation.
- Support the installation of an automatic sprinkler system and a bin insulation layer to prevent spontaneous combustion.
