About Birwelco USA Inc.

Birwelco USA Inc. (BUSA) is a leading supplier of specialized services and support for fired heaters and furnaces from design concept to turnkey implementation. Solutions include studies, on-line services, revamps and complete rebuilds, all focussed on minimizing downtime and maximizing return on investment. Understanding each customer’s unique needs, and delivering the optimized solutions to meet them, is at the core of every BUSA project.


Fired Heaters & Furnaces Solutions

BUSA’s heritage can be traced back to the 1950s when the company’s first fired heater was supplied. Since then, BUSA have remained focused on providing advanced heat transfer solutions for the Refining, Petrochemical & Syngas industries.

Through in-depth understanding of process requirements, BUSA can design and supply a custom heater or evaluate and upgrade existing heaters to safely achieve the required objectives and maintain the technical integrity and performance requirements of the design. BUSA has developed and perfected solutions to apply to any heater or furnace need, all backed by engineering know-how and a collective experience unmatched in the industry. These include patented tube support and combustion air compensator technologies to name a few. BUSA has the capability to modify or repair fired heaters and furnaces whilst in service to resolve immediate operational needs. We often combine these activities with other techniques to help ensure the equipment operates safely whilst continuing to fulfil production output requirements.



An engineering company at its core, BUSA has the depth of fired equipment expertise to fully understand the technical needs of the equipment from the operator’s perspective. Our success is achieved through a team consisting of chemical, mechanical, structural and design disciplines augmented with specialists in the fields of Combustion CFD Modelling, Damper Design, TDL Analyzer Implementation and project scope risk reduction/ optimization.

Damper Solutions

Safe operation of API 560 heaters is rooted in the maintaining of negative pressure (draft) internal to the heater. This draft works to draw in the correct amount of combustion air required to support the fluctuating combustion rates and corresponding production rates. While a heater’s draft capacity is set by the heater design, adjustment of that draft relies solely on performance of the heater dampers.

Tube Supports

The number one leading cause of unplanned shutdowns or reduced throughput rates for a fired heater is the imminent or actual rupture of a coil tube.

Today’s heater operation is using newer technology burners with drastically different flame profiles to process the most economical shale crudes. Both factors are contributing to a sharp rise in the frequency and magnitude of coil movements (vertically and laterally) seen during operation, often compromising the existing tube support system.
