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) according to the ignition limit calculated by Le Chatelier's formula, on some condition, there is a possibility of explosion accidents, 2) adiabatic flame temperature is constant at about 1500K under the condition of the ignition limit, and the ignition limit is valued by the product of organic radical and O containing radical, 3) Using the heat balance simulation, if DME or Cyclopentane is added to combustible gases, there is risk of explosion accidents.
