Preface

Carbon dioxide fire suppression systems already exist in the world and decades of development, the technologies become more sophisticated, but because of its effectiveness and fire extinguishing agents concentration and high storage pressure far and halon fire extinguishing system, coupled with the human body has some harm, so for quite a period of halon fire suppression system matures, limiting carbon dioxide fire suppression systems development application, since the discovery of halon on atmospheric ozone layer enormous destructive force is phasing out while alternative systems research achievements of the endless stream of CO2 as a clean, almost to the environment do not constitute pollution of extinguishing agent and again receive attention, in a way that carbon dioxide is used as a cheap, low cost of production, from broad, performance price ratio is quite high, wide, remains a promising fire extinguishing system.

Power system 600MW power plant reference design, the carbon dioxide extinguishing systems recommended as first choice gas fire extinguishing system is based on the above advantages to consider. In particular, its economy and other types of fire-extinguishing system compared to occupy an absolute advantage. It cannot be denied that carbon dioxide fire extinguishing system also has the disadvantage of not be ignored, fire extinguishing concentration high pressure high; storage; in some places, such as the use of dangerous, had drawn attention. We all know, is used to replace Halon fire-extinguishing systems in terms of carbon dioxide system can be regarded as one of the other as INERGEN, heptafluoropropane (FM-200) and other fire extinguishing system in security, fire extinguishing concentration, efficiency and so on are better than the CO2 system. However, due to its relatively high price, coupled with the lack of experience in domestic applications, application promotion also need proof for a period of time. Therefore, the carbon dioxide fire extinguishing system still serves as an important role. Especially in the power plant gas fire system will have a wide range of applications.
