Vergaengineering has the capability to perform thermal design and rating of all kind of new and existing Fired Heaters, customised to the Client’s requests in terms of type of process feed, duty, efficiency, pressure drop, fuels etc.
Fired Heaters design are typically developed according to API Std. 560 (ISO 13705) and applicable standards/specifications as required by the specific project.
Vergaengineering with its qualified staff and sophisticated design and process computer programmes is capable of handling any complex issue related to heat transmission and combustion control, fluid dynamics, heat recovery systems, emissions reduction and noise attenuation.
In-house simulation programs (specifically developed to cover specific needs of Fired Heater designer and users) are used together with the main international and industrially proven software including FRNC-5 Simulation Software (PFR) and Win Heat Thermal Rating & Design Software.
Vergaengineering has recently developed a proprietary software VEDYNSIM®2015 which has been created to simulate the dynamic transient conditions of a Fired Heater and that can predict the dynamic response of any Fired Heater to cyclic or dynamic operation. VEDYNSIM®2015 can be used in order to simulate any non-steady state condition like cyclic operations, conditions during heater Start Up and Shut Down, any upset condition where some physical parameters are suddenly changed, etc. In particular, with reference to cyclic Regeneration Gas Heaters, VEDYNSIM®2015 provides temperature and draft profiles over the cyclic operation in order to verify the design parameters to meet the required ramp-up time and to provide the input for the fatigue analysis of the main heater structural components.
