Summary: | A plant was designed and fabricated to carbonize the low rank coal to high rank
coal that is environmental friendly pilot plant. The outcome of the semi-coke or high rank
coal which are smokeless fuel, high carbon content, low moisture content and high
calorific value. The reason to construct this plant is because the trend has shown that
demand of the high rank coal will be increased. In order to save the cost of the production
cost, the raw material should be decrease. Therefore we must use the existing low rank
coal in the Malaysia rather than depend on the imported high rank coal. Due to the low
rank coal can not be used as a fuel for domestic and industrial purpose; therefore we have
to find the way to change the quality of the coal in the Malaysia. Mathematical model
equation had been constructed to estimate the temperature distribution inside the
carbonization chamber. The temperature distribution curve show concave curves at the
center. This indicates that the carbonization (pyrolysis) of the coal was an endothermic
reaction. Besides that, the simulation with assist with the software Ansys to the
cylindrical packed coal bed also have been done. Undeniable the result get from the
simulation also have a small deviation compare to the experiment. The result is
confirmed that the reliabilities of the product qualities and environmental friendly pilot
plant are suitable for commercialization. |
