Fired Heaters For General Refinery Service

Before design begins, key parameters-such as process fluid flow rate, heat duty, inlet and outlet temperatures, operating pressure, fuel type, design temperature, and allowable pressure drop-are confirmed. These data determine the furnace type, coil arrangement, burner count, and the design of the radiant and convection sections.

The heater comprises both radiant and convection sections.
The radiant section transfers heat to the furnace tubes via high-temperature flames and furnace-space radiation, while the convection section utilizes residual heat from high-temperature flue gas to further heat the process medium.
An optimized heat transfer design improves fuel utilization and minimizes unnecessary heat loss.
The longer the equipment operates, the more significant the cost differences resulting from fuel consumption and thermal efficiency become.

Designs are tailored to specific fuel types based on refinery site conditions.
If a project requires the use of both gas and liquid fuels, a dual-fuel combustion system can be designed to meet process requirements.

Appropriate tube materials and structural configurations are selected based on factors such as medium properties, design temperature, operating pressure, corrosive environment, and heat load.
For high-temperature or highly corrosive operating conditions, materials with superior heat and corrosion resistance are selected to meet project specifications.

The heater's combustion system design addresses more than just ignition; it encompasses combustion stability, furnace temperature distribution, airflow, and flue gas emissions.
We take a comprehensive approach to ensure that heat released by the fuel is transferred to the process medium as efficiently as possible while minimizing the risk of localized overheating in the furnace tubes.
