Explosion Prevention Measures for Solid Waste Shredding System : Effect of Inert Gases on Ignition Inhibition of Mixed Fuel

Abstract

Gasification melting system is necessary for recycling and volume reduction of solid waste. however, many explosions accidents are caused by combustible gases filled in shredding or gasification melting process from gas cylinder and spray-can mixed within bulky waste. In this experiment, inhibition of ignition of mixed fuel composed of C_3H_8,CO and H_2,N_2 or CO_2 as the inert gas is analyzed using a spark plug as the source of ignition. As a result, 1) in waste grinder a lot of attention is needed for DME, because the ignition area of DME is larger than that of C_3H_8 and CH_4,2) according to the ignition limit calculated by Le Chatelier's formula, the security is ascertained at Pyrolysis Furnace, 3) the ignition limit is valued by the pace of increase of temperature and the product of organic radical and O containning radical.
