Direct Fired Heater Efficiency

Efficiency direct fired heaters convert 100 of the fuel being used to direct heat which lowers fuel consumption and operating costs easy to transport direct fired heaters are fairly simple pieces of equipment that can be moved to where heat is needed.

Direct fired heater efficiency.

Although the example illustrates the energy savings of direct gas fired vs. However there are some cases where an indirect fired heater is the better choice. Direct fired heaters are both more efficient and less expensive than indirect fired heaters. There is a wide variety of heating configurations.

Outside air enters the unit at point c and is either filtered or not. Based on method outlined in api 560 annex g procedure intended for fired heaters burning liquid or gaseous fuels. If desired a quantity of returning room air can be added b to this outside air in a balanced fashion to assure a constant total airflow. Below is a diagram of a direct fired air heater.

Direct fired heaters are both more efficient and less expensive than indirect fired heaters. Tulsa heaters midstream 3 measuringfired heaterefficiency this guide will teach you the process of measuring and calculating your heater s efficiency so you can optimize your plant and save money. Choice depends on fuel cost thermal efficiency temperature desired size of the heat load. A direct fired heater is a style of heater in which a burner provides hot gasses that transfer their heat energy to a process liquid or gas flowing directly through coils installed inside the heater vessel.

Direct fired heaters can utilize radiant and or convection heat transfer sections and can be configured in many different ways depending. Direct fired gas heating is one of the simplest and most cost effective methods for heating air. Indirect gas fired ahus direct gas fired ahus are attractive when compared with most other heating sources. However there are some cases where an indirect fired heater is the better choice.

Direct fired air heaters are typically less expensive and more efficient than indirect fired units as direct firing units converts nearly 100 of the combustion gases used to hot air. Having a thorough understanding of all of the differences between these two heater types will ensure you choose the optimal solution for each project.
