Furnace Screening
A Furnace Screening is a comprehensive on-site industrial furnace assessment, trending combustion data at the burner level over time.
- PSNERGY Combustion Service Technicians onsite for one day
- Installing portable combustion monitoring equipment on the furnace to watch combustion at the same time over time
- Trending relevant continuous combustion data (Any of: Excess O2, CO, NOx, Combustion Air Pressure, Gas Pressure)
- Working with the customer's team to control furnace fire rate throughout its range to screen function of control valving and turndown operation. Note: furnace must be operating.
- Working with customer’s maintenance team to review historical furnace issues
- Analyzing the data for variations (time to time, burner to burner, zone to zone, setpoint vs actual, etc.)
- Verifying valving (Motorized Control Valves, Gas Flow Regulators, Butterfly Valves, Adjustable Limiting Orifice Valves, etc.) is correct for the control schematic and are functioning correctly
- Calculating tube flux on radiant tube burners to identify potential tube life issues.
- This can be performed if there is enough information available to perform the tube flux and current fire rate calculations. A tube drawing is needed.
