It’s Not Alive!

Baron von Olsträd’s Sketchbook #8 Baron von Olsträd’s new comic pokes fun at perceptions. Though the literary Frankenstein’s Monster was calculating and coldly intelligent, most people seem to think of this character as brainless and bumbling, maybe even goofy. It’s all a matter of how the character is portrayed commonly, and the instances with which Read More

Don’t Choke Your Furnace

Baron von Olsträd’s Sketchbook #7 In today’s illustration, the Baron attempts to appeal to our humanity by depicting a personified furnace, suffocating for want of oxygen. Combustion furnaces should be equipped with filters, both on the gas and air lines, which must be checked periodically for blockage. The job of a filter is to strain Read More

FAQ: Burner Control Units – Flame Signal Strength

Q: I’ve got a PF-19 flame safety system incorporating PFU 760 burner control cards, and I keep faulting-out. It seems to be due to loss of flame signal, but I can visually verify flame. How do I check the flame signal on my PFUs? What could be causing this problem? A: Elster Kromschröder burner controls Read More

How Low is Your Purge Time?

Baron von Olsträd’s Sketchbook #6 The Baron’s latest doodle imagines a dangerous game where irresponsibility is rewarded. For those of you who might not know, “purge time” is a phrase commonly used to refer to the length of time given to changing the atmosphere in a furnace, prior to lighting the burners. This is a Read More

FAQ: ValVario Valves

Q: One of my old VAS valves needs to be replaced. What’s the best way to order a new one? A: The VAS series of solenoid valves is part of the valVario family of products, designed to offer compact, modular solutions for industrial gas piping. If you are experiencing a failure with a VAS valve, Read More

FAQ: Ignition Electrodes for Pilot and Industrial Burners

Q: I need some new spark ignitors for my burners. Is that something that I can buy from Combustion 911? A: Combustion 911 carries stock of the components required to create ignition electrodes (also called “spark ignitors”) and ionization electrodes (also called “sense electrodes” or “flame-rods”) for a wide range of Elster Kromschröder pilot and Read More

FAQ: Electrode Adapters and Interference Suppression for Pilot and Industrial Burners

Q: I need to replace a few of the connectors that allow the ignition cable to interface with the spark plugs. Can you explain the differences between the various types you carry? Specifically, when should you use “interference suppressed” models? A: The electrode connectors you’re referring to are also typically called “electrode adapters,” “spark plug Read More

FAQ: Slow Opening (Dampened) Solenoid Valves

Q: What are the advantages to using a slow opening valve? I notice that it is an option for the VAS solenoid valves for gas. Are slow opening valves used for air, also? A: Slow opening solenoid valves (or “dampened” solenoid valves) are available for both gas and air control. VAS solenoid valves are manufactured Read More

FAQ: Elster Kromschröder Product Labels and Type Codes

Q: I have several Elster Kromschröder products in my facility, and it is extremely difficult for me to try to order spares from Combustion 911, because every time I call, the reps ask me for more information. I’ve been asked for photographs of the product labels, but I don’t have any idea what the strings Read More

Futility

Baron von Olsträd’s Sketchbook #5 The Baron’s new comic illustrates the flaws of doing the same thing over and over again, and expecting different results. In one example, the only impacts to this behavior are frustration and a lingering thirst. In the other example, frustration certainly plays a part, though the additional consequences can be Read More
