粉塵和氣體爆炸室

爆炸室用於測量易燃粉塵、氣體、蒸氣和混合混合物的爆炸特性，如最大爆炸壓力、最大壓力上升率、爆炸下限和上限以及極限氧氣濃度。用於測試粉塵爆炸的爆炸室有兩種標準尺寸 - 20 公升（CA 20L™）和 1 m3（我們的 CA 1M3™）。通常用於氣體和蒸氣的爆炸室必須大於 5 公升，因此建議使用CA 20L爆炸室。

應用

使用爆炸室的測試方法是認證機構、大學和其它研究機構用來確定粉塵、氣體和蒸汽危險特性的一套標準測試方法的重要組成部分。從這些測試中獲得的資訊對於設計緩解和保護措施（如爆炸通風裝置、自動化抑制或部分惰性化）至關重要。

Explosion chambers are used for measurement of explosion characteristics of flammable dusts, gases, vapors and hybrid mixtures, such as maximum explosion pressure, maximum rate of pressure rise, lower and upper explosibility limits and limiting oxygen concentration. There are two standardized sizes of the explosion chambers for testing dust explosions – 20 liters (our CA 20L™) and 1 m3 (our CA 1M3™). The explosion chamber for gases and vapors has to be larger than 5 liters, so our CA 20L is recommended for this purpose. 
 

APPLICATIONS

Testing methods using the explosion chambers are an essential part of a standard set of tests used by certified bodies, universities and other research organizations to characterize the hazard properties of dusts, gases and vapors. The information received from these tests is critical for design of mitigating and protective measures, such as explosion venting devices, automatic suppression or partial inertization.
