Modular Redundancy
Electrostatic precipitators rely on stable, high-voltage corona fields to charge and collect dust. Traditional line-frequency T/R sets limit performance and waste power.
Standard T/R sets operate at 50/60 Hz, creating large voltage ripples. The peak voltage is limited by spark-overs, forcing the average operating voltage to remain low, which drastically reduces particle charging.
When a spark occurs, standard T/R sets take 100ms or more to recover, during which the electric field collapse lets untreated smoke plumes escape through the exhaust stack.
Old SCR-controlled systems draw massive reactive power with low power factors (typically 0.5 - 0.6), inflating industrial energy bills and placing heavy strain on the electrical infrastructure.
ModuPower® replaces slow line-frequency transformers with advanced high-frequency switch-mode power, stabilizing the corona field and maximizing energy delivery.
Operating at 25-50 kHz, ModuPower® generates a near-flat DC voltage. This allows the system to operate much closer to the spark-over threshold, maximizing corona power and capturing sub-micron particulates with up to 30% higher efficiency.
By using multiple parallel IGBT power modules, ModuPower® provides inherent redundancy. If a module fails, the remaining units continue running, keeping the ESP online. Microsecond-speed spark detection senses spark-overs and recovers power in less than 1ms, eliminating visible smoke stack releases.
Select an application below to see how ModuPower® solves emission peaks and improves collection rates in active industrial setups.
Managing heavy, resistive cement dust loads and fluctuating gas conditions.
Capturing rapid fume surges and fine metallurgical dust particles.
Optimizing fly ash collection and meeting stringent PM limits.
Cement kiln gases contain high concentration of resistive dust, causing back-corona in traditional systems. ModuPower®'s pulsed charging mode controls the electrical field dynamically, preventing back-corona, maintaining stable operations, and keeping emissions below 5 mg/m³.
Steel plants generate heavy, cyclic smoke peaks. When sparks occur frequently, traditional T/R sets shut down repeatedly, allowing heavy dust puffs to escape. ModuPower®'s fast spark-sensing shuts off and restarts power in under 1ms, keeping emissions steady.
Fly ash from coal and biomass boilers consists of fine, abrasive particles that are highly sensitive to electrical field strength. ModuPower® supplies high average operating voltage to maximize particulate charge and collection, ensuring compliance with strict PM2.5 guidelines.
ModuPower® systems are built to the highest industrial standards. Every transformer undergoes 100% full-load testing before shipment. Measurements demonstrate high power factor and stable KVDC outputs.
