Monitoring Combustible Gases in Kilns
Featured Product from Control Instruments Corp.
A new white paper by Control Instruments, "Monitoring Combustible Gases in Kilns," discusses the hurdles involved with monitoring combustible gas concentrations for safety and key points to consider.
- Heating all sample-wetted parts of the analyzer and sampling system to 250°C will prevent condensation. The sample stays intact. The measurement includes all combustible vapors.
- Sample pumps cannot provide the same level of reliability as an aspirated sampling system and should be avoided.
- A flame-based detector has the best chance to measure the wide range of combustible vapors that might be present. A flame temperature type will include the widest possible range of combustible gases and vapors, including non?hydrocarbons such as hydrogen and carbon monoxide.
- Flammability data for organic binders may be difficult to obtain. A rough estimate for the Lower Flammable Limit in air is 50% of stoichiometric. Another useful rough estimate is one pound of binder per 340 standard cubic feet of air (50 grams per normal cubic meter).
- Near the Flash Point, the vapor pressure tends to double for every 10°C rise in temperature. Small changes in temperature can have a large effect. Cooling the sample a bit can condense out half the combustibles.
