Protect your plant with a TRAX Furnace Draft Study before the upgrade, not after
For energy industry organizations, major changes to your furnace air/gas system, fuel changes, or control changes can lead to excessive pressure excursions in the furnace and ductwork during severe transients. If not properly controlled, transient events have the potential to bring about furnace or duct implosions and expensive repairs.
TRAX conducts a Furnace Draft Analysis to examine process and controls changes in a high-fidelity simulation before these changes are implemented in your plant. Our studies examine severe transient scenarios that cannot be examined with a typical steady state analysis. Each study includes scenarios such as master fuel trips, fan trips, and equipment failures tailored to the proposed plant changes.
Changing fuel brings several challenges to operating the furnace air-gas system. TRAX can help you navigate these potential issues.

A draft analysis is helpful during major equipment changes, when problems arise, or when processes need optimization. Our clients seek studies for…
As part of every analysis, TRAX assesses plant controls for compliance with NFPA-85 industry code for the prevention of fire, explosion, and implosion. In addition, we explore controls strategies to optimize plant operation and mitigation strategies for explosion and implosion protection. These strategies are tested on the plant model and tuned for optimal performance while avoiding nuisance trips.
Conducting a furnace draft study during an equipment or controls upgrade is an important part of ensuring the safety and reliability of the plant with new configurations. It can help a plant achieve NFPA 85 compliance while avoiding nuisance trips and implosion of equipment — improving plant safety, reliability and efficiency.
A furnace draft analysis begins with building a dynamic model of the existing plant, replicating both the plant process and control system.
SAFETY
•
Prevent furnace implosion
•
Prevent ductwork/equipment pressures from exceeding design limits during abnormal operation
•
Reduce/eliminate positive furnace pressure excursions for operator safety
CONTROLS CHECKOUT
•
Ensure compliance with current NFPA 85 code
•
Tune to prevent nuisance trips
•
Retune controls for more effective responses
COST EFFECTIVENESS
•
Potential insurance savings
•
Reduce costs by using tested controls mitigations compared to boiler strengthening (potential savings in millions of dollars)
PROCESS RELIABILITY
•
Ensure that new equipment is properly sized
•
Increase operation efficiency
•
Investigate actuator stroke times
