1. What is an Industrial Boiler Sizing Calculator?

Definition: This calculator determines the required boiler capacity based on steam demand and enthalpy values.

Purpose: It helps engineers and facility managers properly size boilers for industrial applications to ensure efficient operation.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( C \) — Boiler capacity (kg/h)
• \( SD \) — Steam demand (kg/h)
• \( E \) — Enthalpy (J/kg)

Explanation: The steam demand is divided by the enthalpy to determine the required boiler capacity.

3. Importance of Proper Boiler Sizing

Details: Correct boiler sizing ensures energy efficiency, meets steam demand requirements, and prevents over- or under-sizing which can lead to operational issues.

4. Using the Calculator

Tips: Enter the steam demand in kg/h and enthalpy in J/kg (default 2257 J/kg for water at 100°C). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is steam demand?
A: The amount of steam required by your industrial processes, typically measured in kilograms per hour.

Q2: What is enthalpy?
A: The heat energy required to produce steam from water at a given pressure and temperature.

Q3: What's a typical enthalpy value?
A: For water at 100°C, it's approximately 2257 kJ/kg, but varies with temperature and pressure.

Q4: Should I include a safety factor?
A: Yes, most applications add 10-20% to the calculated capacity for peak demand and future expansion.

Q5: How do I determine my steam demand?
A: Sum the steam requirements of all connected equipment and processes during peak operation.
