Acoustic coupling in industrial furnaces is an issue that appears to have become more prevalent as designs increase the volumetric heat density of furnaces, and burner technology is required to meet more-stringent emission requirements. The problems associated with acoustic coupling appear in the form of either large oscillations in the heater pressure or tonal and high-level emitted noise. Although the...

Direct-fired heaters find wide application throughout the chemical process industries (CPI) and are common in petroleum refineries, where they are used to preheat petroleum or petroleum-derived feedstocks in advance of downstream process operations. Since excessive internal tube fouling occurs above certain temperatures, designers often try to keep temperatures down by over-specifying the heat transfer...

An innovation that improves the steelmaking efficiency of an electric arc furnace (EAF) by adding calcium carbide to the process has been developed by NuFlux, LLC (Warren, Ohio), a producer of steelmaking fluxes, and Carbide Industries LLC (Louisville, Ky.;, which makes calcium carbide for acetylene production. The technology has been tested in commercial furnaces, and the companies...

  Industrial furnaces, or direct-fired heaters, are only as good as the burners that supply them with thermal energy for heat transfer and endothermic chemical reactions. This article presents equations that permit calculation of such important burner-operating characteristics as flame length, flame diameter, ignitability, and flameout conditions for both very high and very low velocities. The data...

    Fired heaters are used considerably in the chemical process industries (CPI), for heating crude oil in the petroleum refining and petrochemical sectors. Unfortunately, fired heaters are often taken for granted and neglected more than other equipment in terms of operation and maintenance. Proper care and attention to these heaters can prolong run lengths and increase reliability and safe...

A coal-gasification reactor that resembles a metals smelter and operates in two cycles (oxidation and reduction), alternately producing hydrogen and syngas, is being developed by Diversified Energy Corp. (Gilbert, Ariz.; and Alchemix Corp. (Carefree, Ariz.). In the oxidation cycle (diagram, left), steam is injected into a bath of molten iron-tin alloy to form iron oxide and...

    A wake-up call for plant maintenance The new Simatic Teleservice Adaptor IE (photo) facilitates cost-effective remote maintenance of machinery and plants. In acute service cases or emergencies, an email can be sent via the device. The engineer then scans the plant status via remote connection and carries out modifications. A new version of the adapter with Industrial-Ethernet interface has...

  Large reductions in the emission of pollutants have been reported in the operation of a novel type of municipal solid-waste treatment plant. A group from the Hong Kong University of Science and Technology’s Dept. of Chemical Engineering ( has reported test results recently conducted on a municipal-solid-waste (MSW), co-combustion pilot plant — a novel design...

The Linz, Austria-based VAI Division of Siemens Industrial Solutions and Services (Erlangen, Germany; is commercializing a smelt-reduction process for recycling metal oxide wastes. The ZEWA (zero waste) process, developed by a consortium of companies in a research project under the EU’s Fifth Framework Program, eliminates the need to dispose of slag, dust, sludge or scale...
