Industrial Source Book: Improving Process Heating System Performance

Improving Process Heating System Performance: A Sourcebook for Industry is a development of the U.S. Department of Energy (DOE) Advanced Manufacturing Office (AMO) and the Industrial Heating Equipment Association (IHEA). The AMO and IHEA undertook this project as part of a series of sourcebook publications developed by AMO on energy-consuming industrial systems, and opportunities to improve performance. Other topics in this series include compressed air systems, pumping systems, fan systems, steam systems, and motors and drives.

This Sourcebook outlines opportunities for energy and performance improvements in process heating systems, and is intended to help the reader identify improvement opportunities in their own facilities. This Sourcebook is not a substitute for a rigorous engineering-based assessment and evaluation of the technical and economic potential of any process heating improvement.

Setting Up the Siemens Combustion Controls SQM5


The Siemens Combustion Controls SQM5 reversing actuators are used for the positioning of flow control valves, butterfly valves, dampers, or any application requiring rotary motion.

The SQM5  actuators accommodate control input signals of 4 to 20 mA, 0 to 135 Ω, 0 to 10 Vdc, 0 to 20 mA, position proportional and floating control. The available output signals include 4 to 20 mA, 0 to 135 Ω, 0 to 10 Vdc, 0 to 20 mA, and 0 to 1000 Ω. SQM5... actuators are available with up to six internal, easily adjustable switches.

A selection of exchangeable circuit boards provide a variety of functions including auto/manual selector switch, manual forward/reverse toggle switch, zero and span adjustment, parallel or master/slave operation, split range control, input signal override, and selectable electronic linearization.

The SQM5 is engineered for precision. It is particularly well suited for applications requiring a high degree of modulating accuracy and repeatability.
The SQM5 actuator may be mounted in any position. A selection of mounting brackets and shafts provides installation flexibility and allows for the simple replacement of most competitive actuators.

SQM5 actuators are uniquely suited for both industrial and commercial applications. The high level of accuracy permits precise modulating control of industrial process and process heating applications, often significantly enhancing performance and product quality.

In commercial and industrial burner applications requiring high turndown and reliable ignition, the auxiliary switches can be applied to create separate positions for burner ignition and low fire. In dual fuel applications, additional switches can be used to create separate high fire, low fire and ignition positions for each fuel. The economy position switch is used to drive the actuator to the full closed position when the burner is off.
