爆炸抑制系統（IEP）

爆炸抑制系統由三部分組成：探測器；控制單元；和抑制器。如果發生點火，火球從點火內核膨脹，壓力波（由溫度升高產生）在火焰前沿前行。爆炸壓力檢測器被配置為在幾毫秒內響應特征壓力增加。 抑爆控制單元接收來自壓力傳感器的檢測信號并向抑爆器發送釋放信號。抑制劑以高速和高速注入受保護的容器，使用專門設計的噴嘴來分散抑制劑并吞沒正在生長的火球。這會迅速冷卻火球，減少進一步燃燒并降低爆炸壓力。大多數爆炸抑制系統的設計中不可或缺的是化學或機械爆炸隔離系統，以降低火焰/爆炸傳播到其他連接的過程設備的風險。

An explosion suppression system consists of three components: a detector; control unit; and suppressor(s). In the event an ignition occurs, the fireball expands from the ignition kernel with the pressure wave (created by the increase in temperature) traveling ahead of the flame front. Explosion pressure detectors are configured to respond to the characteristic pressure increase within milliseconds.

The explosion suppression control unit receives the detection signal from the pressure sensors and sends a release signal to the explosion suppressor(s). Suppressant is injected into the protected vessel at high rate and high velocity, using specially designed nozzles to disperse the suppressant and engulf the growing fireball. This rapidly cools the fireball, mitigating further combustion and reducing the explosion pressure. Integral to the design of most explosion suppression system is a chemical or mechanical explosion isolation systems to reduce the risk of flame/explosion propagation to other connected process equipment.
