Multicyclone
Multicyclone - device used to remove particulates from the gas stream. A cyclonic separation is a method of removing particulates from an air, gas or liquid stream, without the use of filters, through vortex separation. Rotational effects and gravity are used to separate mixtures of solids and fluids. The unit is intended for use in boiler plants, power plants, agriculture, timber industry and similar industries.
Working principle
A cyclonic separation is a method of removing particulates from an air, gas or liquid stream, without the use of filters, through vortex separation. Rotational effects and gravity are used to separate mixtures of solids and fluids
The multi cyclone consists of separation elements arranged in number of rows. As the gas flows through the separation element, the blades direct the flow in a spiral path. The inertial particles are separated from the gas stream by the inertial forces.
The separated particles fall down into the ash collection hopper, from where they are removed through the ash dispenser.
- Multicyclone cell configuration options: 4×4, 5×5, 5×5, 6×5, 6×6, 7×6, 7×7, 8×7, 8×8, 9×8, 9×9;
- Range of Flow rate, m^3/h: 12800-97200
- Maximum separation efficiency: 85 %
Electrostatic precipitator
Flue gas cleaning from solid particles is being fulfilled by electrostatic precipitator. Electrostatic precipitator consists of a chamber with electrical fields.
Working principle
The flue gas to be treated is led into a casing through an inlet nozzle. While the flue gas is passing through the casing or chamber, the particles receive an electric charge and electrical forces cause the particles to be deposited on the colleting plates, forming a dust Iayer. The gasses then leave the ESP through an outlet nozzle.
At certain intervals the plates are cleaned by rapping devices, which dislodge the dust cake and let it, fall down to the flat bottom. The flat bottom is cleaned by a bottom scraper which discharges the dust out from the ESP.
The filter has a flat bottom with a drag scraper. The drag scraper is heavy duty design, suited to clean the entire bottom once per 65 seconds (the time is set with reference to the fuel/process). The hydraulic axis is designed to automatically take up expansion variation. The axis is supported by wheels to avoid wear at the bottom plates.
Flue gas ventilator
Flue gas ventilator – device used to provide pull of flue gasses in combustion systems. System can contain one few flue gas ventilators depending on needed system parameters and overall arrangement.
