Clark Laboratories | BTU Calorific Value

Analysis for Quality, Environmental Compliance, and Commercial Value

What is BTU Testing?

BTU (British Thermal Unit) or Calorific Value Testing measures the amount of energy released when a fuel is completely combusted.

This test is one of the most important indicators of fuel value and combustion efficiency.

ASTM D5865 is commonly used for determining the gross calorific value of coal and petroleum coke.

Why BTU Testing Matters

Energy content directly impacts:

Fuel purchasing decisions
Boiler efficiency
Furnace performance
Cement kiln operations
Power generation economics

Higher BTU values typically indicate greater energy potential and increased commercial value.

Applications

BTU testing is commonly used by:

Utility Companies
Industrial Boilers
Cement Plants
Refineries
Commodity Traders
Fuel Procurement Teams
