Combustion Analyzers Made Easy
Combustion Analyzers Engineered to be Easy
When it comes to performance testing of residential commercial and industrial combustion equipment, the importance of sensor technology and how and what is being measured cannot be understated. Combustion analysis is not hard, nor should it ever be!
For most of its 103 years, Bacharach has been designing innovative technology that leads the way in electronic combustion analysis. From handheld portability to ease of use and minimal maintenance, Bacharach’s Fyrite® family of analyzers deliver high reliability at low cost — exactly as they are designed to do.
CO2 vs O2
All Bacharach analyzers use O2 sensors to measure oxygen directly. An O2 test is more reliable than a carbon dioxide test for providing better accuracy and efficiency. Here’s why:
Changes in O2 concentrations are much larger and easier to read than the relative change in CO2 for a given change in excess air - and results are less sensitive to variations in the chemical composition of the fuel. Oxygen measurements go to zero when combustion is perfect or when the process is using excess fuel, but O2 rises when combustion is running on the preferred excess air side of the process. CO2 readings can be the same on both the excess fuel and excess air sides of the combustion process. It is only possible to determine what the CO2 measurement is telling you by making extra adjustments to the appliance and analyzer, which cost the technician more time and money. Adjusting to the wrong CO2 reading wastes fuel, produces more CO, costs time and increases risk. While oxygen sensors have a shorter life than CO2 sensors, the accuracy and time savings is well worth it in the long run.
THE DATA YOU NEED TO SEE
Some analyzers show only limited data on the display, often not readily showing the key readings for oxygen concentration, stack temperature and CO concentration together. The ability to see more than 1 or 2 key measurements on the display is essential. The user’s ability to select the most important measurement readings they need to see at one time - in graphic or numeric format - is a critical feature built into Bacharach combustion analyzers. Bacharach displays are engineered to show critical data together (up to 4 or 5 lines of data at once) so at-a-glance analysis is easy and efficient. Bright readings with backlighting make results easy to see in any environment. Trending graphs, hotspot indicators and safe-range parameters show real-time readings during your analysis*. Sensor indicators and instrument diagnostics provide important status checks at the push of a button or automatically on every startup.
*Certain features not available on all models.
From time to time, sensors, batteries, probes and other consumable parts need to be replaced in any gas analyzer. Sealed units require regular factory service for maintenance and calibration, greatly increasing the cost of ownership in a very short time. Also, service time can be lost waiting for batteries to recharge. Bacharach instruments are designed to make periodic maintenance easy and affordable with self-diagnostics and easy access to user-replaceable sensors, probes, batteries, filters and water traps.
REMOVABLE PROBES & FILTERS
Hot flue-gas samples can create condensation in the probe as they cool. And if the probe filter is saturated, it can also leach moisture or soot into the instrument, which can shorten the life of the sensors and electronics. Detaching the probe from the instrument after combustion testing will help to quickly clear accumulated gases and moisture and enable better filter inspection/replacement. Integrated probes do not offer that advantage and, if they become damaged or clogged, require the entire instrument to be returned to the factory for service rather than just replacing or servicing the probe. All Bacharach analyzers feature removable probes.
Sensors are an essential part of combustion analysis and, due to the breakdown of the chemicals they contain, they are subject to wear. Advances in technology enable longer sensor life and reliability but they still require periodic calibration and replacement. In Bacharach analyzers, O2 sensors self calibrate on every start up in clean air environments and all CO sensors will zero. The CO sensor should be calibrated on a known gas concentration (or exchanged) at least yearly or as required by code. Bacharach analyzers are designed with user-replaceable B-Smart® sensors to minimize the instrument downtime and factory service costs due to depleted sensors. No tools are required; just 2 fingers to pluck the expired sensor from its holding cup and to put the new one in its place. Bacharach’s B-Smart® Sensor Exchange program conveniently delivers pre-calibrated sensors directly to you on your pre-determined schedule - no need to remember calibration dates or buy calibration gas.
