Changes that occur in the burning of ceramic items will depend on the composition of the mixture of materials used for the ceramic body, the heating temperature and the conditions of combustion \/ burning atmosphere (oxidation, reduction and neutral).<\/span> Overall burning the biscuits can be divided into four phases:<\/span>
\n a. Phase evaporation (water smoking):<\/strong> namely mechanical water discharge phases.<\/span> To set the temperature of the end of the drying stage is very difficult, but a temperature of 150 ^{\u00b0<\/sup> C is regarded as the final stage of discharge water temperature mechanical.<\/span><\/p>\n}

b. Stage of dehydration:<\/strong> at this stage combustion is done slowly, because burning too quickly will result in ceramic objects bursting \/ rupture.<\/span> Chemically combined water released from the ceramic body at a temperature between 200 ^{\u00b0<\/sup> C and 460 o<\/sup> C.<\/span><\/p>\n}

c. The oxidation stage:<\/strong> This stage occurs at temperatures between 400 ^{0<\/sup> C-1100 0<\/sup> C.<\/span> When burnt clay, while the carbon content of the oxidation process is not perfect it will lead to the emergence of black bintikbintik and small holes on the surface of the ceramic body.<\/span> This will impact the movement and heat glaze becomes uneven.<\/span><\/p>\n}

d. Stage vitrification:<\/strong> ceramic body and the maturation phase takes place at about 900 ^{0<\/sup> C.<\/span> At this stage there is melting and recrystallization.<\/span> When the temperature is raised further, the melt will penetrate into the pores deeper and produce a solid material.<\/span> At this stage, the flux will react with clay and tends to soften, and finally when the temperature rises above the vitrification point, it will come out so that the gas bubbles which lead to blisters appear.<\/span> This is because the flux in boiling ceramic body.<\/span><\/p>\n}

e. Stage soaking:<\/strong> process maintain the combustion temperature at a certain point some time (soaking period) in order to reactions that occur evenly across the ceramic part.<\/span> If the process is deemed to have sufficient soaking period, the furnace can be turned off and cooled within a reasonable time or at least 18 hours.<\/span> After the cold stove, and the temperatures have reached below 100 ^{\u00b0<\/sup> C, the furnace can be opened a bit, a few moments later the goods can be unloaded \/ removed.<\/span><\/p>\n}

Principles of Combustion Reaction<\/strong><\/span>
\n Fuel wood, charcoal, oil for burning ceramic is a fuel containing carbon and to react with oxygen (air) that generate heat.<\/span> The main thing in this combustion reaction is how to drain the air (oxygen) to taste the carbon-containing fuels.<\/span> In principle, before the combustion process occurs, for solid fuels (wood and charcoal) or liquid (oil) should be turned into a gas that can cause heat.<\/span><\/p>\n

Change the fuel into gas will only occur when the combustion temperature rises.<\/span> The higher the temperature, the faster the combustion process occurs.<\/span> During the combustion process takes place there needs to be controls in the following:<\/span>
\n a. Temperature.<\/strong><\/span> Temperatures during the combustion process can be measured with thermocouples and pyrometers installed in the furnace.<\/span><\/p>\n

b. Speed Stove Burner (Burner).<\/strong><\/span> Burning speed can be adjusted by increasing or decreasing the amount of fuel in the combustion chamber by adjusting the fuel valves.<\/span> By adding the fuel, the incoming air is needed for combustion and must be increased so that there is a balance.<\/span> Burning speed can be controlled through a thermocouple or pyrometer and adapted to stretch the planned burning.<\/span><\/p>\n

c. Time.<\/strong><\/span> The time required in the combustion process is determined by three factors, namely high and low temperature combustion to be achieved, the speed of temperature rise, and important capacity furnace.<\/span> The greater the capacity of the furnace the longer time required for combustion.<\/span><\/p>\n

d. Pull the Chimney.<\/strong><\/span> Pull chimney governed by skepticism or damper mounted between the furnace and the chimney.<\/span> The pull of the chimney will affect your fuel consumption efficiency and the temperature rises.<\/span> When the pull of the chimney is too high \/ fast hot gases do not have enough time to provide heat to the ceramics so that it takes more fuel to be able to raise the temperature.<\/span> If the chimney is too small tug \/ low then the heat of combustion is not smooth and uneven.<\/span><\/p>\n

e. The atmosphere combustion.<\/strong><\/span> Atmosphere burning question is oxidation, reduction, or neutral.<\/span> Atmosphere oxidation will occur when air is needed for combustion excessive compared with the fuel, the reduction will occur when air is needed less, while neutral will occur when the air and fuel balance.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
