Impedance pipe heating is a long-established and accepted — but poorly understood — pipe heating technology. While a simple and elegant way to heat a pipeline, impedance pipe heating technology often is viewed incorrectly and misunderstood as a method to heat process piping.
Safety oven designs — standard Class A, low oxygen Class A and explosionproof — incorporate specific components and heating methods to inhibit unintended combustion reactions. Aside from components, one of the biggest differences is how they approach the fire triangle.
Many processes involve the heating of volatile, flammable solvents, and these require some type of safety oven to mitigate the risk of a fire or explosion. These ovens fall roughly into three categories, depending on which side of the fire triangle they address.
When selecting a safety control system for a combustion application, it is essential to recognize that many trade-offs will need to be weighed before making a decision. In simple terms, the reliability will decrease when adding safety to any system.
The spectrum of applications found in the process industries means that burner designs must vary widely. Smaller burners are utilized in paint booths, ovens and furnaces while larger burners are specified for incinerators, thermal oil heaters and oxidizers.
Industrial dryers are not one-size-fits-all systems. Key differences between drying inorganic and organic material mean that when researching drying technologies, it is important to start with the product to be dried.
Fatal accidents involving industrial ovens and dryers are relatively rare, fortunately. Incorporating safety features can enhance operator and technician safety when working near industrial ovens and dryers.
In so many factories these days, the focus is “Safety is no accident,” and personnel well-being is prioritized more than ever. The benefits of a safety culture in an industrial setting are many: improved worker happiness and retention, reduced insurance costs and higher productivity.
One of my favorite things to do near the end of the year is review the most popular content on our site — in the last year and overall. It helps me recognize topics that may warrant more coverage, and it can prompt me to revisit still-popular topics I may have missed in 2019.
The use of optical fiber for temperature sensing is expanding beyond safety applications. Optical sensors are replacing spot sampling in implementations that require accurate heat measurement and control.
