WHAT IS STATIC PRESSURE, AND WHY IS IT IMPORTANT WITH TODAY S APPLICATIONS?
Static pressure refers to the amount of compressive or expansive energy in a fluid or gas. This energy will be present whether the fluid or gas is in motion or at rest. Static pressure is the means of producing and maintaining flow against a resistance. High static pressure burners have been developed to accommodate the more modern, flow restrictive appliances and to assist with low draft conditions. A drop in static pressure can cause problems that range from delayed ignition, rumbles, and pulsation to the inability to adjust the burner for clean operation. In these cases, more static pressure is required to ensure uniform, dependable combustion performance under variable conditions. The air handling components of the AFG enable it to develop greater static pressure than the conventional model AF burner (FIGURE 1). The fan in a high static pressure burner starts with enough high pressure to effectively push the products of combustion through the appliance without interruption. The hig
