Abstract

Boiler is a tool that serves to convert water into pressurized steam. In the heat causes heat boiler heat transfer through the water into pressurized steam that is heated from the fuel in the furnace.And often a problem of burning in the boiler is less than the maximum. Because the incoming energy is energy derived from the fuel, there is some energy lost during the combustion process it happens because the fuel has a low heat so that the combustion is not maximal cause the boiler performance is reduced. To avoid this, it is necessary to  maintenance for the boiler component in order to improve performance. Direct method is "input - output method" because this method uses only the heat in the fuel and steam coming from the boiler output. Boiler efficiency of research results from the date of March 27, 2017 until the date of 10 April 2017 with a total average - average efficiency were analyzed, namely 74.4%. On April 3, 2017 the calculated efficiency of 76.57% indicates that the boiler performance is still feasible to operate but on April 4, 2017 the boiler efficiency becomes 71.59%. Boiler efficiency at commissioning, with boiler efficiency of 85.13% and in 2017 done the boiler efficiency calculation theoretically on 27 March until 10 April 2017 with total average 74.4% where the efficiency decrease equal to 10.73%. Factors affecting the efficiency ratio are in the coal content used. Keywords:Boiler, Performance, Direct Method

Abstract

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.
