# Industrial Specification: Prilling Head / Bucket

## 1. Technical Definition
The component of a prilling tower that distributes molten material into droplets for solidification.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-3.0 bar pressure, 200-350°C temperature, 0.1-5.0 mm orifice diameter**. Failure boundary: **Material yield strength exceeded at 450°C (316L SS: 170 MPa at 450°C), cavitation occurs at vapor pressure &lt;0.1 bar, thermal fatigue at ΔT&gt;150°C**, Mechanism: **Thermal fatigue from cyclic heating/cooling (ΔT&gt;150°C induces &gt;0.2% strain), cavitation erosion at vapor pressure threshold, stress corrosion cracking in chloride environments (&gt;50 ppm Cl⁻ at &gt;60°C)**.

### 2.1 Analytical Physics Model
Governed by the **Darcy-Weisbach Pressure Drop**:

> **Primary Equation**: $\Delta P = f \cdot \frac{L}{D} \cdot \frac{\rho v^2}{2}$  
> **Engineering Impact**: Critical for sizing CIP (Clean-In-Place) pump heads.
