Steam Condensate Heating

Overview

Engineering reference data for Steam Condensate Heating in material science and properties.

Key Formulas

Stress

$\sigma = \frac{F}{A}$

Force per unit area.

Strain

$\varepsilon = \frac{\Delta L}{L_0}$

Change in length per original length.

Hooke's Law

$\sigma = E \varepsilon$

Stress proportional to strain in elastic region.

Thermal Expansion

$\Delta L = \alpha L_0 \Delta T$

Length change due to temperature.

Variables

Practical Application Notes

Engineering Constants Explained

The equations use specific conversion factors for common engineering units:

• *960 in Equation (1): Approximate latent heat of vaporization at atmospheric pressure (Btu/lb)
• *500 in Equation (2): Conversion factor combining water density (8.34 lb/gal) and minutes-to-hours (60 min/hr): $8.34 \times 60 \approx 500$
• *60 in Equation (3): Minutes-to-hours conversion for gas volumetric flow (CFM to cubic feet per hour)

Important Assumptions

These equations assume:

1. Steam condenses completely (100% quality reduction)
2. Sensible heat in condensate is negligible or recovered separately
3. No flash steam losses in the condensate return system
4. Steady-state conditions with constant inlet/outlet temperatures
