# Industrial Specification: Burner Assembly

## 1. Technical Definition
A combustion system component that generates controlled flame for heating applications in industrial preheating stations.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.0 bar fuel pressure, 800-1200°C flame temperature, 10-100 kW thermal output**. Failure boundary: **Fuel pressure below 0.3 bar causes flame instability; flame temperature exceeding 1300°C initiates nozzle material degradation; thermal cycling beyond 5000 cycles induces thermal fatigue cracking**, Mechanism: **Thermal fatigue from cyclic heating/cooling (coefficient of thermal expansion mismatch between Inconel 718 nozzle and 316L stainless steel housing); flame instability due to laminar-turbulent transition at Reynolds number &lt;2300; material oxidation at temperatures above 1150°C following Arrhenius kinetics**.

### 2.1 Analytical Physics Model
Governed by the **Heat Sterilization F0 Lethality Model**:

> **Primary Equation**: $F_0 = \int_{0}^{t} 10^{(T-121.1)/z} dt$  
> **Engineering Impact**: Validates microbial reduction integrity for aseptic packaging.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| T | Process Temp (°C) | **$T \in [800-1200°C]$ °C** (Per `temperature_range`) |
| t | Exposure Time (min) | Engineering Constant |
| z | Z-value | **10 °C** (Standard for *C. botulinum*) |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Fuel-air ratio deviation beyond stoichiometric ±5% (λ=0.95-1.05) | 8 | Incomplete combustion producing 500-1000 ppm CO emissions | Closed-loop lambda control with zirconia oxygen sensor feedback to modulating valve |
| Thermal shock from 800°C to 200°C cooling in &lt;60 seconds | 8 | Radial cracking in ceramic insulation with crack propagation &gt;2 mm | Gradual cooldown protocol limiting temperature gradient to 10°C/second via controlled fuel ramp-down |
