  • Method for firing ceramic honeycomb bodies
    Patent number: 6325963
    Abstract: The invention relates to a method of firing a green ceramic honeycomb structural body containing an organic or carbonaceous material which is characterized by removing at least a portion of the carbonaceous material released prior to reacting within the firing atmosphere during the initial firing of the green honeycomb structural body. The invention also relates to a tunnel kiln, which includes a vestibule region, a carbonaceous material release region, having a plurality of removal zones, located downstream of the vestibule region and a sintering region located downstream of the carbonaceous material release region. The tunnel kiln further includes an exhaust removal system which operatively communicates, via offtake openings located in each removal zone, with the release region for removing released carbonaceous material.
