Ash Screw Conveyor System
- Screw conveyors are sometimes used for dry bottom ash. The screw mechanism moves the material within an enclosed trough, reducing the risk of material spillage and dust generation.
- Advantages: Screw conveyors are simple, compact, and efficient for conveying both wet and dry bottom ash.

Screw Cooler | Bottom Ash Handling System
Bottom ash is a heavier, coarser byproduct that collects at the bottom of the furnace or combustion chamber in power plants, waste-to-energy facilities, and biomass boilers. Unlike fly ash, bottom ash is larger, denser, and more abrasive, which requires a different handling system. -
Fly Ash Conveyor Systems
- Screw conveyors are sometimes used for dry bottom ash. The screw mechanism moves the material within an enclosed trough, reducing the risk of material spillage and dust generation.
- Advantages: Screw conveyors are simple, compact, and efficient for conveying both wet and dry bottom ash.

Screw Conveyor for Fly Ash
Biomass boilers are increasingly used in power generation and waste-to-energy plants due to their ability to convert organic materials into heat and electricity. However, one of the challenges associated with biomass combustion is the handling of the ash byproduct, which includes bottom ash and fly ash. Effective ash handling is crucial to ensuring safe, efficient, and environmentally responsible operations. Here’s an overview of complete solutions for biomass boiler ash handling.

Hot Transport Conveyor
A hot transport conveyor is a type of conveyor system designed to transport materials at elevated temperatures. These conveyors are used in industries where materials need to be moved at high temperatures, such as in power plants, steel mills, cement plants, and waste-to-energy facilities.

Direct reduction, hot briquetted iron plants conveyor
In Direct Reduction (DR) plants, particularly those involved in the production of Hot Briquetted Iron (HBI), conveyors play a critical role in handling and transporting the hot materials throughout the production process. Hot Briquetted Iron (HBI) is a form of Direct Reduced Iron (DRI) that is compacted into briquettes while still hot to facilitate easier handling and transportation, as well as to prevent oxidation.

Hot Direct Reduced Iron (DRI) conveyor
A Hot Direct Reduced Iron (DRI) conveyor is a type of specialized conveyor system used in the steel industry to transport hot DRI material, which is produced through the direct reduction of iron ore. DRI is typically produced in rotary kilns or shaft furnaces using a reducing gas (usually natural gas) to convert iron ore (Fe2O3 or Fe3O4) into sponge iron (Fe). The DRI material is often extremely hot when it is transported, requiring specialized handling equipment.

MT/HT High-Temperature Screw Conveyors
High-Temperature screw conveyor is a conveyor system designed for medium-high temperature (MT series) and high-temperature (HT series) materials, designed to move materials while providing cooling effect, this type of conveyor consists of a hollow screw, the screw Surrounded by a jacket filled with a cooling medium such as water or air. As the material travels along the length of the screw, it is exposed to a cooling medium in the jacket, which helps reduce its temperature. This is especially useful in applications where the material being conveyed generates heat during processing, or requires cooling prior to further processing or packaging.

Thermal Heating & Cooling for Screw Conveyors
Bootec manufactures screw conveyors designed for thermal heating and cooling processes where indirect heat transfer is required or preferred. Heat transfer is accomplished through contact with an external jacket (bolt-on or integral) and/or through the transfer auger itself. The material is heated or cooled while being transferred down the length of the conveyor. A variety of heating or cooling media may be used.
-
Cooling screw conveyors
Cooling screw conveyor is specially used for conveying high temperature products after burning or high temperature products, Heat indirectly transfers from the product by introducing a heat transfer medium such as cool water through a special trough jacket and/ or through the pipe and hollow flights of the screw processor. Achieving the specified exit temperature of the product is accomplished by calculating the surface area of the screw processor and designing the system flow to match the heat load requirements of the application. The temperature of the conveyed material entering the screw inlet is 450 degrees, When discharging, the temperature should drop below 100 degrees, which is suitable for conveying high-temperature fly ash, cinder, rubber powder, carbon black and other materials.

Heating screw conveyors
The function of a high-temperature screw conveyor is to transport materials exposed to high temperatures (typically above 200°C (392°F)) from one location to another. Conveyors consist of a screw or auger that rotates within a trough or tube to move material forward. The screws are usually powered by an electric motor, and the conveyor can be inclined or horizontal, depending on the application.
