1. Product Overview & Strategic Market Positioning
El BLESP1W-100W Series Dry Electrostatic Precipitator (Dry ESP) is an advanced, high-voltage industrial dust collection system that harnesses intense electrostatic fields (Coulomb force) to meticulously separate suspended particulate matter from exhaust gas streams. Serving as the ultimate defense in heavy-duty flue gas treatment, this system has been deeply optimized in dimensional design, electrical control, and aerodynamics. It serves as a highly robust, cost-effective, and fully compatible drop-in replacement for premium legacy brands such as GE (Alstom)® or FLSmidth® Coromax® ESP models, allowing manufacturing facilities to upgrade their aging infrastructure without incurring exorbitant OEM capital expenditures.
Industry Applications at a Glance:
Extensively deployed in coal-fired power plant boilers, cement manufacturing (rotary kiln heads and tails), metallurgical sintering plants, steel mills, and heavy chemical processing facilities for pre-desulfurization dedusting and final stack emission control.
Core Advantage Summary:
The system is uniquely capable of managing monumental gas volumes up to 2,300,000 m³/h at scorching temperatures reaching 400°C. Astoundingly, it achieves this while operating at a phenomenally low pressure drop of just 200~350 Pa, saving immense electrical costs for Induced Draft (ID) fans annually.

3. Working Principle & Structural Composition
An electrostatic precipitator is a highly sophisticated dust removal device used to separate particles from a gas stream utilizing electrostatic force (Coulomb force). It is widely recognized as one of the most efficient dedusting technologies in the world, ideal for purifying large-scale exhaust gas during intense industrial production.
Ionization & Charging: Two primary electrodes—a discharging electrode (cathode wire) and a collection electrode (anode plate)—complete the function of gas purification. When the two electrodes are energized with high-voltage direct current, an intense electric field is created. Under this field strength, a corona discharge occurs, ionizing the gas stream and generating a massive cloud of free electrons and anions. As dust passes through, it collides with these ions and becomes highly negatively charged.
Migration & Rapping: The charged suspended particles are instantly driven toward the positively charged collection plates by electrostatic repulsion and attraction. Accumulated particles are then removed from the collection plates at periodic intervals by a mechanical rapping system (hammering mechanism). The heavy agglomerated dust falls directly to the base hoppers for safe disposal, while the purified exhaust gas is safely expelled into the atmosphere through the stack.

4. Core System Advantages
Choosing the BLESP Series means selecting ultimate reliability and massive reductions in long-term operational costs. Here are the 5 core advantages of our system:
Ultra-Low Operating Resistance
Operating at an aerodynamic resistance of just 200~350 Pa, our ESPs drastically reduce the electrical load on your Induced Draft (ID) fans, saving massive energy OpEx compared to restrictive baghouses (>1500 Pa).
Extreme Temperature Tolerance
Built entirely of robust metallurgical components, the system handles continuous flue gas temperatures up to 400°C safely, completely eliminating the risk of filter fires or thermal media degradation.
Massive Volume & Heavy Load
Designed for mega-facilities, it effortlessly processes up to 2,300,000 m³/h of gas volume and easily manages punishing inlet dust concentrations reaching 1,300 g/Nm³ without clogging.
Zero Consumable Replacement
Unlike baghouses that require frequent, labor-intensive bag replacements, our rigid discharge wires and heavy-duty collection plates offer decades of maintenance-free service, enabling uninterrupted production.
Modular Open Architecture
Engineered with adaptable cross-sectional dimensions, making it the perfect modular system for retrofitting existing casings or serving as primary filtration upstream of a Oxidador térmico regenerativo (RTO).
5. Structure & Material Craftsmanship
The unparalleled longevity and collection efficiency of the BLESP1W-100W Series stem from its meticulous heavy-industrial engineering, premium material selection, and advanced aerodynamic distribution technology.

6. Typical Application Scenarios
The sheer volumetric capacity, aerodynamic design, and thermal durability of the BLESP Series establish it as the primary dedusting choice across the world's most demanding heavy industries.
🏭 Cement Manufacturing (Kiln Tail)
Challenge & Mechanism: Rotary kilns produce massive gas volumes at 400°C laden with abrasive clinker dust. Built with heat-resistant steel and wide-passage spacing, our ESP efficiently recovers valuable clinker dust without clogging, emitting only clean air.
⚡ Power Generation (FGD Pre-dedusting)
Challenge & Mechanism: Coal-fired boilers emit continuous high volumes of sub-micron fly ash. Installed upstream of the Flue Gas Desulfurization (FGD) tower, the ESP's multi-field design captures 99.9% of fly ash, protecting wet scrubbers from siltation.
⚒️ Metallurgy (Sintering Machine)
Challenge & Mechanism: Sintering exhaust is highly corrosive and laden with sticky metallic dust. Equipped with specialized anti-corrosive collecting plates and an extreme-shear rapping system, it forces sticky metallic particulates safely into the hoppers.
