FLUE GAS CLEANING
the essential basis for low emissions and reliability
flue gas cleaning for emission reduction
The first step towards reliably low flue gas emissions and compliance with regulations.
SAVE ENERGY flue gas cleaning solutions are high-performance separators that remove 99% of particles and pollutants. They thus meet the highest ecological requirements and legal standards.
These systems are designed for continuous operation and demanding industrial environments and form the basis for safe, efficient and sustainable energy plants.
dry electrostatic precipitator
The SAVE ENERGY dry electrostatic precipitator is a high-performance separator that has been specially developed to minimize operating costs, maximize separation efficiency and achieve an availability of around 99%.
How it works
In the SAVE ENERGY dry electrostatic precipitator solids are separated from the flue gas by the effect of an electric field. The electrically neutral dust particles are charged by the spray electrodes. The effect of the electric forces transports the particles to the precipitation electrode, where they are separated from the gas stream.
High-voltage ionization in electrostatic precipitators
The SAVE ENERGY dry electrostatic precipitator is designed as a plate separator. A controlled high-voltage field of up to 86kV is generated on the discharge electrodes. A high field strength builds up in the immediate vicinity of the discharge electrodes. In this active zone, the free electrons are strongly accelerated (gas discharge). This ionization is accompanied by a faint glow and is referred to as a corona. The corona discharge at the tips of the spray electrodes creates gas ions, which attach themselves to the particles and electrically charge the dust particles.
Particle transport for efficient flue gas separation
The charged dust particles are transported in the flow-through separator chamber between the discharge and collecting electrodes across the direction of gas flow to the electrically grounded precipitation plates (anodes) and separated from the gas stream. This flow, which moves from the active zone through the passive zone to the precipitation electrode, is referred to as electric wind.
Continuous operation and mechanical cleaning of flue gas
The separated particles form a dust layer on the collecting plates. Due to the grounding of the collecting plates, the dust particles lose their charge and can be cleaned mechanically. Both the collecting plates and the discharge electrode frames are tapped cyclically at different intervals by two hammer mills. The dust particles are detached by the mechanical impulse and fall into the ash hopper. The system runs continuously throughout the entire process, ensuring very high availability.
Advantages
Low maintenance and service costs
Easy access, automated dust discharge via step hopper walls and remote monitoring systems that reduces manual work and downtime.
Low operating costs
Intelligent energy management results in low electricity consumption and efficient operations.
