Sizing a Burner That Won't Struggle at Peak Load

Sizing a burner to exactly match peak heat demand leaves no margin for equipment aging, heat loss, or future load growth. A safety margin on top of measured peak demand gives realistic headroom.

The Formula

Burner Capacity = Peak Heat Demand × (1 + Safety Factor% / 100)

Worked Example

A process with 200 kW peak demand and a 15% safety factor:

Capacity = 200 × 1.15 = 230 kW

How to Use This Calculator

Enter the Peak Heat Demand of the process.
Optionally adjust the Safety Factor (defaults to 10%).
Select Calculate to get recommended burner capacity.
