Model: UEPC-170
Product Name: User Explosion Pulse Cleaning (UEPC) System
Manufacturer: USER MÜHENDİSLİK
Application Area: Slag removal in superheaters of biomass power plants and high-temperature deposition zones
1. GENERAL DESCRIPTION
The UEPC system is an advanced, directional-pulse cleaning technology developed to remove stubborn slag accumulations in the superheater zones of biomass power plants. It operates online (in real-time) under flue gas temperatures up to 1500°C, using systematic, high-energy acoustic pulses to dislodge ash and slag from heat exchange surfaces.
2. OPERATING PRINCIPLE
The UEPC system operates via an internal energy conversion mechanism structured with controlled fluid dynamics. A precisely balanced mixture is triggered through synchronized activation, generating a directional acoustic wave that induces vibrational stress on slag layers. These stresses weaken adhesion and allow the deposits to detach from surfaces.
Note: The system regulates internal fluid characteristics and volumetric equilibrium through uniquely configured components. Synchronization between these elements is essential for system efficiency and performance.

4. EFFECT ON SLAG LAYERS
🛠 Mechanical Effect
- Shock waves break the molecular bonds within slag
- Detached slag disintegrates and falls from the surface
- Supersonic jet flow inside the horn ensures broad impact coverage
🌡 Thermal Shock Effect
- Sudden temperature differential occurs post-detonation
- Adhesion weakens, slag fractures and detaches
♻ Sustained Cleaning Efficiency
- 1 pulse per hour prevents solidification of layers
- Clean surfaces enhance heat transfer and overall efficiency
