How can you determine boiler air in-leakage and calculate air heater leakage?

The Boiler Exit Probe can be used further downstream in the rear convection pass from HVT testing. Since it does not require water or air supply lines, the Boiler Exit Probe is less cumbersome than the HVT probe, and it can be used in an environment up to 1,000°F. When used in conjunction with the HVT probe, the Boiler Exit Probe can be used to determine boiler air in-leakage, temperature stratification from the furnace to the stack or air heater leakage.

Our Boiler Exit Probe is fabricated from 304 Stainless Steel tubing with a type "K" thermocouple. A digital thermometer is used to determine temperatures. A gas sample can be obtained from the boiler exit probe by using a gas analyzer.

A complete kit is composed of the following:

 

- Boiler Exit Probe of Desired Length
- Stainless Steel Armored Lead Wire
- Digital Thermometer
- Clear Tubing
- ECOM-AC Gas Analyzer (Recommended)
