Boiler/Burner Combustion Air Supply Requirements and

Heat transfer-enhancing turbulators may have the same effect as adding an economizer because they can add to the pressure loss through the boiler and thereby detract from combustion air fan performance. Whenever turbulators are added to the flue gas side of a boiler, a stack measurement of excess oxygen and carbon monoxide should be made before

Boiler 101 | What is a boiler? - Home | American Boiler

Watertube Boiler In watertube boilers, boiler water passes through the tubes while the exhaust gases remain in the shell side, passing over the tube surfaces. Because tubes can typically withstand higher internal pressure than the large chamber shell in a firetube, watertube boilers are used where high steam pressures (3,000 psi, sometimes
