222 廃棄物処理システムにおける防災対策について : 混合燃料に対する着火抑制効果

Abstract

Gasification melting system is necessary for recycling and volume reduction of solid waste. Many explosion accidents, however, are caused by combustible gases filled in shredding or gasification melting process from gas cylinder and spray-can mixed within bulky waste. In this experiments which were conducted for inhibition of ignition in these process, using a spark plug as the source of ignition and mixed fuel composed of CH_4,CO and H_2,N_2 or CO_2 as the inert gas was added to pre-heated mixed fuel-air flow. As a result, 1) according to the ignition limit calculated by Le Chatelier's formula, on condition that waste contents too less moisture or has high heat quantity, there is a possibility that explosion accidents, 2) effect of ignition inhibition is valued by tendency to formation of organic and inorganic radicals.
