Siemens offers a comprehensive range of Energy and Environmental Solutions that can improve energy efficiency up to 40% and increase productivity from 1% to 7%. We offer the resources, expertise and technology to drive your energy consumption down while improving productivity. At Siemens, our goal is to help you improve your energy intensity, improve your profit margin, help secure your future and reduce your carbon footprint. One way Siemens is doing this is through the upgrade of electrostatic precipitator control systems.

Electrostatic precipitators filter exhaust gases emitted from industrial plants, power plants and refuse incineration plants, removing harmful pollutants such as dust, soot and aerosols. Sometimes, changes in operational conditions or new emissions regulations require an increase in ESP efficiency. In this case, plant operators can either mechanically expand the precipitator itself or upgrade by installing new control equipment.

Installing new equipment is a faster, lower cost solution than mechanical expansion. Plant operators can gather information about the status of an ESP and its optimization potential by installing testing equipment that mimics the planned upgrades. Test operations typically involve rounding-up all the necessary components, transporting them to the site, setting them up and connecting them to the ESP. This work can take several days and may lead to interruptions in ESP operation – possibly bringing the entire plant to a standstill.

Siemens state-of-the-art container based mobile testing unit offers ESP operators a mobile option for on-site testing and optimization of collecting efficiency. It also provides operators with the status of a connected ESP within the shortest possible time, while also providing data on ways to improve performance and save energy. Easy transport and quick installation reduce precipitator downtime and help to minimize production losses..

On the outside, the testing unit looks like a standard blue shipping container. Inside the 20-foot-long container, however, is a complete high-voltage power supply and all the control and optimization systems necessary to operate one ESP field on-site. The pre-installed equipment includes an IGBT-based converter, a high-voltage rectifier, a TR-set, and all the necessary cables.

The container comes equipped with a PC workstation for running pre-installed test procedures and requires only minor adjustments to adapt to specific local conditions. Its advanced power electronics and proprietary software optimize energy use and reduce harmful plant emissions. The testing unit can also be used to bridge malfunctions and ESP failures.

The device travels by truck from plant to plant in response to customer requests. Setup and commissioning of the mobile testing unit takes about one business day, roughly one-third of the time required to construct a test installation on-site from the ground up. In addition, the unit can be installed with minimal interruptions to ESP operation.
