Precision Heat Treatment & Thermal Processing Systems

Complete Combustion delivers licensed, P.Eng-stamped combustion system design, multi-zone temperature control architecture, and regulatory compliance engineering for industrial heat treatment furnaces and thermal processing equipment across USA and Canada. Operating under a PEO Certificate of Authorization, we engineer tight-tolerance thermal solutions compliant with NFPA 86, CSA B149.3, and CSA/NEC standards.

Core Engineering Capabilities

1. Multi-Zone Temperature Uniformity & Firing Strategies

• High-Velocity Burner Integration: Selecting and orienting high-momentum burners that entrain chamber gases, generating intense convective circulation to equalize temperatures throughout the work zone.
• Pulse-Firing & Excess-Air Control: Programming pulsed firing routines to maintain high convective gas velocity and chamber turbulence even when firing at low holding inputs.
• Multi-Zone Independent Modulation: Engineering multi-zone temperature control loops where individual burner banks modulate independently based on localized workload thermocouple feedback.

2. BMS & NFPA 86 Compliance

• NFPA 86 Pre-Purge Logic: Mathematical calculation and programming of mandatory fresh-air purge volumes before pilot or main burner ignition.
• Dual SSOV Valve Trains: Valve train engineering featuring double safety shutoff valves, POC verification, and automatic vent valves compliant with CSA B149.3 and TSSA.
• Flame Detection & Safeguards: Integrating UV or IR flame scanners capable of reliable flame discrimination under intense glowing refractory backgrounds.

3. Thermal Insulation & Structural Enclosure Engineering

• ASTM C680 Heat-Transfer Profiling: Mathematical analysis of steady-state heat transfer through multi-layer wall, roof, and car-bottom hearth assemblies.
• Refractory Material Selection: Engineering lightweight ceramic fiber module linings or durable dense castables for high-wear hearth perimeters and door jambs.

Supported Furnace Types & Thermal Processes

• Car-Bottom Furnaces: Large-capacity mobile car-bottom furnaces for heavy casting stress-relieving, large weldment annealing, and forging preheating.
• Batch Box & Pit Furnaces: Stationary batch ovens, drop-bottom aluminum solution treating furnaces, and pit-type tempering furnaces.
• Continuous Heat Treating Systems: Roller hearth, mesh belt, and pusher furnaces for continuous annealing, hardening, and brazing operations.

Frequently Asked Questions

How do you achieve tight temperature uniformity inside a large car-bottom furnace?
We engineer multi-zone burner arrays utilizing high-velocity burners that fire tangentially or alternate across upper and lower zones. Combined with pulse-firing or excess-air modulation, this maintains high internal gas circulation and eliminates thermal stratification.

Can you engineer a combustion modernization without replacing the furnace shell?
Yes. We routinely engineer retrofit packages that replace outdated burners, valve trains, and flame safeguard panels while retaining the existing furnace steel shell and car mechanism.
