Furnace Performance Audits

Furnace Profiling: First Level Audits

First Level Audits are 3 or 5 day furnace process gas composition, temperature, and time profiling, complete with a formalized report of the data collected.

ARI schedules a time to visit your site with monitoring equipment. Fittings are installed on the furnace to attach up to four 1/8” stainless steel sample gas tubing lines that are connected to the Laser Gas Analyzer. Other sampling connections may also be installed for temperature and pressure monitoring.

The furnace is then operated through normal process cycles to collect operational baseline data.

The data include furnace gas composition for as many runs that can be completed in the contracted time. The gases measured are CO, H2O, NH3, O2, N2, CO2, H2, and CxHy. The accuracy for these measurements is typically less than .25% of full scale.

Process data are provided in a written report and in eletornic spreadsheets. No analysis of the data is provided.

At the end of the test, ARI removes the monitoring system and caps the sensor ports in the furnace.

Furnace Profiling: Second Level Audits

Second Level Audits are 5 or 7 day furnace process gas composition, temperature, and time profiling, complete with a formalized report of the data collected. The report includes analysis of the data and recommendations for actions.

ARI schedules a time to visit a customer site with the monitoring equipment. Fittings are installed on the furnace to attach up to four 1/8” stainless steel sample gas tubing lines that are connected to the Laser Gas Analyzer. Other sampling connections may also be installed for temperature and pressure monitoring.

The furnace is then operated through normal process cycles to collect operational baseline data.

The data include furnace gas composition for as many runs that can be completed in the contracted time. The gases measured are CO, H2O, NH3, O2, N2, CO2, H2, and CxHy. The accuracy for these measurements is typically less than .25% of full scale.

ARI then provides an in depth analysis of the results based on extensive experience with monitoring metal treating furnace processes. ARI meets with the customer to review the findings and make recommendations for process improvements. The results and recommendations will be included in a formal report.

At the end of the test, ARI removes the monitoring system and caps the sensor ports in the furnace.
