Intended for industrial process-heating operators and users of all types of industrial heating equipment, IHEA’s “Fundamentals of Industrial Process Heating” online learning course is scheduled to begin March 13.
Submerged combustion is a method of direct-contact heating that has been practiced in a range of industries for several decades. This article explains the basic concepts of submerged combustion. It can be applied to process heating of industrial aqueous solutions and slurries as well as to the evaporation of solutions for the purposes of concentration or volume reduction.
In the 21st century manufacturing world, process heating systems have become an essential part of the overall manufacturing operation for many industries. Almost every finished consumer product requires some form of heat-treating method, whether it is baking, curing, annealing or drying at some point in the production process.
Combustion safeguard system provide continuous, automatic protection against the buildup of combustible fuel mixtures due to flame failure or other faults in ovens, boilers, furnaces and other heating equipment.
Two types of flame sensors generally are used on industrial burners: flame rods and ultraviolet scanners. While each can perform the essential role of safeguarding industrial combustion systems, this article will focus on ultraviolet scanners.
