reaction, allowing the combustion to occur at lower temperatures. Because the catalytic process operates at a lower temperature than the thermal process, less auxiliary fuel may be required in the catalytic process to preheat the waste gas. The heart of an incinerator system is a combustion chamber in which the waste stream is burned

    Rotary kilns work by processing material in a rotating drum at high temperatures for a specified retention time to cause a physical change or chemical reaction in the material being processed. The kiln is set at a slight slope to assist in moving material through the drum. Direct-fired kilns utilize direct contact between the material and

The waste gas generated during the combustion process is fed to an after burning chamber, in which the minimum temperature of between 850 and 1200 C is maintained for a residence time of at least 2 seconds. The waste gas volume from this process is generally assumed to be about 7,000 m3 (dry) per Mg of waste

    Dunting is a special type of crack which occurs from stresses caused during firing and cooling. These stresses primarily occur during two critical points of firing called silica inversions which occur at 1063 degrees F (573 degrees C), and 439 degrees F (226 degrees C). At these inversion points, the structure of the silica molecules rearranges

    If CO 2 is to be separated, as much as 100 megawatts of a typical 500-megawatt coal-fired power plant would be necessary for today’s CO 2 capture processes based on the alkanolamines [4–6]. Therefore, it would be highly desirable if the flue gas mixtures can be used for CO 2 conversion but without pre-separation of CO 2

During the beginning of the bisque firing, the last of the atmospheric water is driven out of the clay. If it is heated too quickly, the water turns into steam while inside the clay body, which can cause the clay to burst. Featured Video

    Jun 11, 2018 The terms oxidation and reduction refer to how much oxygen is in the kiln's atmosphere while the kiln is firing. An oxidation atmosphere has plenty of oxygen for the fuel to burn. A reduction atmosphere occurs when the amount of available oxygen is reduced. This may not sound like things that will affect your pottery, but it can
