Jet Fuel Application, by Matthew Guillot
Application To heat jet fuel in an airline delivery vessel to keep it from freezing. Customer Requirements Pipe thread construction, fit into the existing design, thermostat controlled and must be explosion-proof. Problem The potential customer had recently received a large price increase for their vendor. The customer was already using a competitor’s pipe thread equivalent…
Freeze Protection of Cooling Tower Basins
Abstract Seasonally shutting down a cooling tower by draining the tower is often not possible for three reasons: (1) In large buildings, the central core must often be cooled, even in sub-freezing weather (2) in sections of the United States, the occasional warm winter day necessitates sporadic air conditioning operation and (3) year-round one or…
Crude Oil Application
Problem: Heating oil to 130°F with a flow rate of 400,000 lbs/hr, 1300 psig and an operating pressure of 800 psig. Solution: Considering the extreme flow rate the KW requirement was significant at 800 KW. Indeeco split the requirement between (2) 18″ – 400 KW circulation heaters. With the high pressure in mind 600 #…
Electrically Heated Oven
A universal-style, 850°F electrically heated oven has work space dimensions measuring 36 inches wide x 36 inches deep x 36 inches high. The oven chamber is heated by Incoloy-sheathed tubular elements, while a 600-CFM, 0.5-HP recirculating blower provides front-to-rear universal airflow to the workload. The oven features 6-inch insulated walls, an aluminized steel exterior and…
Mercury Abatement Heaters, by: Matthew Guillot
The Challenge Mercury is in a lot of byproducts of flue-gas emissions from industrial production. Since mercury is extremely poisonous every effort to remove it from processes is needed to keep our environment safe. The Solution Indeeco is able to produce industrial finned tubular process air heaters that heat the carbon to improve its absorption…
SPECIAL FOCUS: Infrared Heating Infrared HEATS UP
Infrared (IR) technology is currently used in a wide range of industrial applications such as: The electronics industry for drying solder resists Food processing for browning and sterilization Coating/finishing for drying and curing Textiles for drying and sealing Plastics for softening Printing for drying Manufacturing/engineering for degreasing, preheating, and shrink fitting Infrared energy causes the…
Impedance Heating
For decades, plumbers have thawed frozen water pipes by connecting portable welder electrodes to both ends of the frozen section and running a low-voltage current through the pipe. Effectively, the pipe becomes a heating element, melting the ice inside. That, in its simplest form, is impedance heating. In industrial applications, a multitap a.c. transformer supplies…
Comparing Heat Sources
When comparing heat sources used for drying processes there are a few variables: the primary carriers are usually solid or gaseous but may take the form of waves or other radio frequency technologies. Fossil fuels constitute the majority of commercially available energy sources used to generate heat. The supply of these fuels is diminishing, however,…
Electric Heating Elements
Electric heating elements in the form of coil, ribbon or rod (Fig. 1) made from alloys such as nickel-chromium, iron-chromium-aluminum and refractory metals are widely used throughout the heat-treating industry. They are found in both low- and high-temperature furnaces and perform well in cyclic-duty service. Let’s learn more. The temperature of a heating element and…
Short-Wave Infrared Speeds Up Aerospace Tool Heating
This article discusses two different ways that infrared (IR) heating can be used. One is a high-heat process requiring preheating of the tools/dies, and the other is a lower-temperature process where IR is cleaner and more efficient. Can infrared be used in your process to improve energy efficiency? Short-wave infrared emitters have allowed Mettis Aerospace…
