We can perform thermal designs and ratings of all kinds of new and existing fired heaters (FHs) and customize them, based on the type of process feed, duty, efficiency, pressure drop, fuels, etc.

FHs’ designs are typically developed according to API Std. 560 (ISO 13705) and any applicable standards/specifications required by a specific project.

Thanks to our qualified staff and sophisticated design and process software, we can handle any complex issues related to heat transmission and combustion control; fluid dynamics; heat recovery; emissions reduction, and noise attenuation.

We use both in-house simulation programs, specifically developed to support FH’s designers and users, as well as the main international software, such as FRNC-5 Simulation Software (PFR) and Win Heat Thermal Rating & Design Software.

We developed the proprietary software VEDYNSIM®, which can simulate the dynamic transient conditions of a FH and predict the dynamic response of any FHs to cyclic or dynamic operation. 

VEDYNSIM® can be used to simulate any non-steady-state condition, like cyclic operations conditions during the FH’s start-up and shutdown, or any upset conditions in which physical parameters are suddenly changed.

For FHs operating under cycling conditions (such as, for instance, Regeneration Gas Heaters), VEDYNSIM® provides temperature and draft profiles over the cyclic operation to verify the FH’s ramp-up time and provide the inputs for the fatigue analysis of its main structural components.
