Development of graft earthenware ceramic firing stove design from the usage of wasted gas fire and heat from tunnel stove in stoneware ceramic firing process

The research based on wasted gas fire and heat in ceramic continuous tunnel firing stove in Dinoyo Ceramic Craft Center of Malang Indonesia. Gas fire and heat is a wasted heat from tunnel in stoneware ceramic firing which reached 1250°C temperature. In firing process, there’s extreme heat from wasted gas from ceramic stove’s chimney.. Next, heat produced by wasted gas is used for decorated earthenware firing process, by creating heat sink room as firing room for earthenware. The method is applying decorated earthenware firing stove design exploration. Whereas by designing new firing stove room, attached in the edge of tunnel stove side. Fire from wasted gas is able to reach temperature between 750-900°C allocated in the new firing room. Heat from wasted gas from continuous tunnel or stove is thrown from chimney, they will be flowed into new fuel in form of graft or attached. In this new firing stove which is located in the edge, it needs lower heat, which is 800°C to burn souvenir earthenware. This stove design development then called “graft stove”. This firing room is dedicated to burn souvenir earthenware. Firing room size are 1 m x wide 0,5 m x height 40 cm.
