Claims
- 1. A method of firing a ceramic honeycomb structure containing organic additives, said method comprising the steps of:
- placing a first thermocouple inside the ceramic honeycomb structural body, and placing a second thermocouple directly adjacent to and outside the ceramic honeycomb structural body to detect temperatures at inside and outside portions of the ceramic honeycomb structural body;
- detecting a differential temperature condition between said inside and outside portions of said ceramic honeycomb structure, said differential temperature condition resulting from non-uniform combustion of said organic additives at inside and outside portions of said ceramic honeycomb structure; and
- controlling combustion of burner means based on the detected differential temperature condition.
- 2. The method of claim 1, wherein said first thermocouple is provided in a through hole formed in said ceramic honeycomb structure.
- 3. The method of claim 1, wherein said combustion of burner means is controlled so as to maintain temperatures at said inside and outside portions of the ceramic honeycomb structure substantially constant.
