Inproheat Industries offers direct fired heaters manufactured by Sigma Thermal.
Direct fired heaters are used to shift their existing heat to an intended process – whether it be a gas or liquid that exists in the heater. A single or multi-burner is used for heat generation.
Highly customizable, direct fired heaters are normally available in two styles: the radiant-convective and and the convection.
Radiant-convective heaters are API 560-certified and the most utilized direct fired heater in most applications. Standard designs include a tube used for radiance that works in conjunction with a specialized convection area.
Convection heaters offer a consistent heating environment that places less stress on coils due to a chamber that is specifically for combustion. The circulation of flue gas is also encouraged by these heaters, which helps to maintain the combustible temperature near 1,400F.
Direct fired heaters put performance first while ensuring safety. Both of these qualities are enhanced by extensive and customized control panels that oversee everything from the control of combustion to automation features. This puts clients in control of the performance through expert guidance.
Direct fired heaters can reach efficiency levels of over 90% with the possibility of reaching 93% through the addition of an economizer.
Direct fired heaters can be customized with different burner options like standard models or customized versions, including specialized low emissions models. Multiple types of fuel can also be integrated with direct fired heaters.
Direct fired heaters are frequently used in industry sectors like petrochemical, refinery, mining, and food. Specific applications include furnaces, liquid or gas vaporization, and crude oil heating.
