Convection and conduction heaters are used in heat processing applications to create and apply heat via either a medium such as air or via direct contact.

The four-zone drying system will provide electrically heated convection air and will allow the battery company to scale up operations.

Often, the functionally safer a system is built, the less reliable it becomes. In a continuing discussion of how to handle independent protection layer alarms, this article demonstrates the concepts using the example of a refinery furnace.

When constructing a new canola crushing and oil refining plant capable of processing 2,500 metric tons of canola seed per day, one of the largest Canadian canola producers sought a process heating system capable of mitigating the unavoidable sub-freezing temperatures affecting production during winter.

Solutions for electrically heated steam cracker furnaces are the focus of a joint development agreement inked by BASF, SABIC and Linde. The partners have already collaborated on concepts related to using renewable electricity rather than the fossil fuel gas typically used for the heating process.

The 400°F (204°C) electrically heated shelf oven can be used for heat treating parts. Installed heat input is 15 KW while a 1000-cfm, 1-hp blower provides side-to-side horizontal airflow to the workload.

Industrial heating can be obtained through various technologies such as fuel, electricity and steam as well as hybrid technologies that combine two or more technologies. Fuel-based heating technology is the most common today due to the relatively low prices of fossil fuels.

Pit furnace is designed with a maximum operating temperature of 1750°F (954°C) and gross workload of 1600 lb. Temperature uniformity of ± 25°F at 1650°F (899°C) was documented with a nine-point profile test. 

Since this column will appear in our January issue, I can finally tell you about a project that has been in the works for quite a while: our new eBook on thermal fluid heating for industrial processes.

The horizontal, conveyorized gas-fired and electrically heated convection drying and curing systems are intended for applications to dry off water or cure liquid and powder coatings on products processed horizontally.
