The emissions from natural gas-fired boilers and furnaces include nitrogen oxides (NOx), carbon monoxide (CO), and carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), volatile organic compounds (VOCs), trace amounts of sulfur dioxide (SO2), and particulate matter (PM). Nitrogen Oxides -
Gas är ett av de fyra huvudsakliga aggregationstillstånd materia kan befinna sig i. I en gas rör sig var och en av de ingående molekylerna helt oberoende av de övriga. Ett ämne går vanligtvis från fast till flytande till gas och sedan vidare till plasma när temperaturen ökar. I vissa fall kan dock ett ämne gå direkt från fast till gasfas; detta kallas sublimation. Ett ämne i gasform upptar inte en bestämd volym, utan expanderar tills det fyllt tillgängligt utrymme
In this case, a VOC contains the word “organic” because the chemicals contain a compound of carbon and will easily become a vapor or a gas. Research on VOC Hazards Some off gassing VOCs are thought to be carcinogenic, which means they cause cancer. Other VOCs are considered harmful when they mix with other chemicals as gasses. About Gas Sensors for Leak Detection and Indoor Air Quality (IAQ) Applications, VOC Sensors A gas sensor (often called a gas detector) is a device used to determine the presence and amount of a specific gas or gases. At the core of any gas detection system is a sensor element. Visqueen Ultimate VOC Blok is a 1mm robust chemically resistant co-extruded hydrocarbon, volatile organic compound and gas barrier.
