# Industrial Specification: Fluidization Chamber

## 1. Technical Definition
The chamber where fluidization of solid particles occurs through gas flow in a fluidized bed cooler.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 bar gauge pressure, 20-80°C gas inlet temperature, 0.3-1.2 m/s superficial gas velocity**. Failure boundary: **Minimum fluidization velocity (Umf) below 0.25 m/s causes defluidization; gas velocity exceeding 1.5 m/s leads to particle entrainment; wall temperature exceeding 150°C causes thermal degradation of refractory lining**, Mechanism: **Defluidization occurs when drag force (Fd = 0.5*Cd*ρg*A*Ug²) falls below particle weight minus buoyancy; particle entrainment initiates when gas velocity exceeds terminal settling velocity (Ut = √[4gd(ρp-ρg)/(3Cdρg)]); thermal fatigue from cyclic heating/cooling above 150°C creates microcracks in refractory via thermal stress (σ = EαΔT)**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.
