You find the boiler water-level gauge glass to be empty and the burner firing. What is your course of action? (Assuming the gauge glass to be clear & good working order) A. Blow down the gauge glass to determine where the water level is B. Increase the feedwater supply to maintain the water level C. […]

Shell and tube heat exchangers or plate heat exchangers use a primary fluid such as steam to heat a process fluid. What many people don’t know is that heat exchangers, like the Graham Heliflow Heat Exchanger, have many applications, even in difficult conditions. Graham created the Heliflow to be exceptionally versatile, yielding heat transfer rates […]

Engineers and plant managers in hospitals, schools and industrial facilities are constantly looking to drive down costs by improving energy efficiency in their steam boilers. Most run boilers constantly to produce steam and require high turndown and short payback on their equipment purchases For new applications and retrofits alike, Campbell-Sevey suggests replacing conventional burners with […]

During combustion of natural gas, water in the combustion air changes phase from liquid to gas. As a result, combustion products of natural gas typically contain 11% to 12% moisture, which represents up to 9% of beginning fuel content. With typical economizers, this energy escapes into the atmosphere with heated boiler gases. But a condensing […]

The purpose of installing insulation blankets is to prevent radiant heat loss and save energy. However the wrong blanket styles or poor installation can result in exposed surface areas and unnecessary heat loss. Check out these videos of bad practices we highly suggest avoiding. For highly efficient blankets, Campbell-Sevey recommends Shannon Insultech Thermal Blankets. These […]

Consider Installing Turbulators on Two- and Three-Pass Firetube Boilers Firetube Boilers The packaged firetube boiler is the most common boiler design used to provide heating or process steam in industrial and heavy commercial applications. The American Boiler Manufacturers Association (ABMA) surveyed sales of high-pressure [15- to 350-pounds-per-square-inch-gauge (psig)] firetube and small watertube boilers between 1978 […]

In the HVAC Coil Manufacturing Industry there are primarily three types of manufacturers – OEM, Air Handler, and Custom. Which you use depends largely on your application and the reliability needed, but only one provides the perfect fit and capacity every time. OEM Coil Manufacturers build coils specifically for equipment with larger production runs. Because […]

Within the Food Processing Industry in the Midwest, there were numerous instances of companies requesting assistance in their wash down stations. These food plants include beef, pork and chicken processor companies where the processing areas must be sanitized using very hot water at 165 degrees F or higher. The stations might or might not use […]
