Abstract
Chambers in a continuous furnace were designed. A chamber consists of inlets and outlets of nitrogen gas which is used to discharge burned gas and heating pipes (HP) which are used to keep temperature of fired materials at $1,300^{\circ}C$. Design variables were numbers of inlets and outlets, distance between floor and lower HP ($h_1$), distance between lower HP and fired materials ($h_2$), distance between fired materials and upper HP ($h_3$), temperature of HP, numbers of HP and distance between HP. The numbers of inlets and outlets were determined so that nitrogen gas formed a laminar flow for efficient discharge. All other design variables were determined so that temperature of fired materials is as uniform as possible near $1,300^{\circ}C$. Chambers were produced and temperature was measured at 21 points using thermocouples. The largest deviation from $1,300^{\circ}C$ was less than ${\pm}2.2^{\circ}C$.
