Pulse Fire Demonstration
IRSI has developed their own powerful & versatile pulse firing algorithms for use in multi burner kiln and furnace applications. Pulse firing offers significant fuel savings by only operating the burners at full fire where they should be designed for best efficiency. Then throttling back to low fire or just the ignition pilot. As opposed to a regular throttle controlled burner where the burners usually run for long periods at a varying percentage output that doesn't give the designed for air/fuel flows thereby operating at a reduced efficiency with increased fuel consumption and cost.
Pulse Fire Demonstration Users Guide
You can manually vary the heat output in this furnace using the touchpad to see how our system controls the number of burners at full fire for an output to give equivalent heat output across the bank to a throttled system. Note that the pulse intervals and timing vary to enable a full range of outputs, not just, as may be predicted, an approximation to the closest 1/8 of full output, based on our 8 burner demo. A good way to see this is choose a low output, say 5 percent, and observe that all burners are at low fire for periods of time giving a time averaged output exactly to the controller output.
Stirring or increased hot gas circulation is another key advantage to pulse firing. The efficiency of heat distribution is key to many processes and can save fuel by being improved. Industrial Refractory Services system allows for maximum optimization for our customers by being versatile. As demonstrated by the demonstration above the burners can be cycled in any of many established sequences just by choosing their cycle position from the drop down box and the type of cycle by selecting radio buttons. Plus actual pulse times will have great effects as can be seen above changing the time itself in the top box (note if selecting the constant cycle button the time parameter on this demo is for the entire cycle length so may need to be increased).
Industrial Refractory Services has built these functions in to all installations to date; so we have proven history and credibility. Our system has been designed on the basis that flexibility is key and no two pieces of process equipment or product lines are completely alike. Also the flexibility of our system assists greatly in the time and cost of our installation regardless of the inevitable uniqueness of every installation. We stand firmly behind our capacity to install with any of numerous setups in relatively short time spans. We also provide simple operator interfaces for customer initiated changes at a later date. Post installation changes may be made with or without our assistance, as desired by yourselves or these can be achieved by a remote secure telephone link to the control equipment, assuring yourselves of speedy, cost effective solutions. We believe this is much superior to a rigid one size fits all installation; no matter how technically fancy it is, as ours has many of those features already installed, in selectable configurations. We maintain that no two processes are identical. For example, no two tunnel kilns are completely alike. One may have an unforeseen projection that disrupts the airflow around it making a certain kind of pulsing cycle less effective than another. With our setup you can change settings to solve this in under a minute or we could do it remotely, without extreme callout charges.
