Fired heater draft profile
WebA liquid-fired burner’s design is significantly different from that of any gas-fired burner, and it presents many more challenges during opera-tion than a gas-fired burner. For those reasons, most burners designed for liquid firing are also equipped with gas-firing capability. Therefore, oil burners for process heaters are typi- WebFired heaters designed for refinery applications are generally designed for allowable average radiant heat flux (q r), which is one of the most closely watched design factors of fired heaters for given process application.For determination of average radiant heat flux it is necessary as a first step to determine the radiant heat duty (Q r).All of existing well …

WebJun 1, 2003 · Basically the stack has two parameters height and diameter. More height gives more buoyancy and draft & larger diameter gives smaller frictional losses and better draft. Auxiliary fans (or blowers) can be used to create this draft as well. An induced draft fan will draw the flue gas out of the heater and create a draft.
