<![CDATA[This study aims to determine and compare the results of the syngas volume generated from variations in mixing of galam wood powder and bentonite catalyst coal. This research was carried out by mixing galam wood powder and coal with a mass of 200g which was given a bentonite catalyst. There were 4 variations of mixing ingredients namely 200g galam wood powder and 0g coal, 180g galam wood powder and 20g coal, 140g galam wood powder and 60g coal, 100g galam wood powder and 100g coal which added 50%, 30% and 10% bentonite catalysts from the mass of material in each variation of the temperature. Material in updraft gasification with a temperature of 500oC for 120 minutes or 2 hours. The results showed that variations with a mixture of 200g of galam wood powder and 0g coal were the ones that produced the most syngas. This was due to the density of galam wood powder which was more tenuous so it was more flammable at temperatures up to 500oC. The amount of bentonite catalyst addition also affects the volume of syngas produced, where the more addition of bentonite catalysts the more syngas volume is produced, this is because bentonite contains Al2O3 which has good heat conductivity so the heating rate is faster, due to the heating rate faster makes the syngas volume produced more for 120 minutes when gasification.]]>

<![CDATA[This study aims to determine the water supply / discharge system of water pretreatment station equipment which is then processed for the purpose of operating a steam power plant. In the distribution process, the reliability of the equipment and the resulting discharge will be observed whether it is in accordance with the provisions for the ideal operation or not. The expected discharge is 518 m3 / h according to the water balance so that the plant can operate full load (2x66 MW). With this condition, the company is expected to benefit. In the actual conditions this ideal discharge condition is not achieved so that the impact of the plant cannot operate full load (2x66 MW). With water conditions that do not match these expectations, it is feared that the company will continue to suffer losses. In fact, this study only obtained a maximum discharge of 402.2 m3 / h. From this figure there is a difference in water debit of 115.8 m3 / h. Furthermore, this debit shortage must be overcome so that the generator can meet the maximum full load performance. For long-term steps, standby backup equipment must be provided in anticipation of the operation.]]>

<![CDATA[The use of sand in the cfb boiler function as a coal burner which enters the combustion chamber. Sand in the combustion chamber is lined up and coal enters the combustion chamber. With the entry of coal into the furnace fluidization occurs, where the heat in the sand burns coal that hovers, so that the heat that arises is used to heat the water in the boiler tubes. The remaining coal combustion (ash) wil float/fly inhaled by IDF air. Sand movement is expeted to only always bubbling up ang down in the furnace area only so that complete combustion occurs and the boiler is reliable. Because the bubbling is influenced by air pressure, coal quality, which can cause friction between material (sand and coal) and refractory giving rise to abrasives on refractory. If refractory is abrasive it can cause abrasive on the tube water wall boilers, tube cyclones so that boiler performance will decrease.The use of sand that is not clear is one of the causes of refractory damage in cfb type boilers. So that the cfb boiler remains reliable, the use of sand must be in accordance with the type and size according to the particular boiler.]]>
