Fired heaters operate under demanding conditions. High temperatures, open flame, metal components, process piping, fuel systems, burners, and controls must all work together safely and reliably.
Over time, wear and tear can occur in any fired heater. However, some heater designs provide significantly better long-term reliability than others.
In the latest video from Tulsa Heaters Midstream, Brad Irwin discusses common fired heater problems, why some radiant coils fail prematurely, and what customers should evaluate before selecting a fired heater manufacturer.
When comparing fired heater proposals, it can be tempting to select the smallest and least expensive option.
A compact heater may reduce upfront costs, but fitting too much heat duty into too little space can create serious operating problems.
When a heater is designed too tightly, operators may experience:
A lower purchase price does not necessarily mean a lower total cost of ownership.
If a heater requires repeated coil replacements, refractory repairs, emergency service, or an early replacement, the initial savings can quickly disappear.
One of the most important factors in fired heater design is how heat is distributed across the radiant coil.
Some compact heater designs place tubes close together to reduce the size of the radiant section. While this may reduce fabrication costs, tightly packed coils can create areas of excessive heat exposure.
Spreading the tubes across a properly sized radiant section helps distribute heat more evenly and reduces the risk of localized high temperatures.
This does not always require substantially more heat transfer surface. In many cases, the primary difference is simply providing enough physical space for the existing coil surface to operate properly.
The result can be:
A radiant coil should not be treated as a component that must be replaced every two or three years.
While process conditions, maintenance practices, fuel quality, operating history, and heater design all affect coil life, operators should expect a properly designed and maintained coil to deliver long-term service.
Repeated coil failures may indicate a larger problem involving:
Replacing the failed coil without identifying the root cause may only reset the clock until the next failure.
When Tulsa Heaters Midstream receives a call about a heater problem, the aftermarket team evaluates more than the damaged component.
The process may include reviewing:
This complete-system approach helps determine whether the best solution is an onsite repair, shop repair, major redesign, or complete heater replacement.
When a critical heater fails, customers need more than an engineering recommendation. They need a practical plan that gets the operation running again.
Depending on the situation, Tulsa Heaters Midstream can help customers:
Having engineering, aftermarket, fabrication, field service, and burner management capabilities available through one team can reduce delays during emergency situations.
When evaluating fired heater bids, customers typically compare scope, specifications, delivery, and price.
One question that may not appear clearly on a bid tab is:
Who will answer the phone when something goes wrong?
Before selecting a fired heater manufacturer, customers should consider whether the company has:
A company may be able to outsource these services after a failure occurs, but locating and coordinating outside specialists can add days or weeks to an outage.
For facilities that depend on heater availability, that delay can be far more expensive than the original equipment purchase.
Long-term reliability begins during the initial heater design and purchasing process.
Customers should look beyond the lowest upfront price and evaluate:
A fired heater should be designed not only to meet the required duty, but also to provide safe, reliable performance over many years of operation.
