Abstract

Currently, several material production industries have used self-sustaining power generation systems. Where the most common steam power plant system is found as an option to be used as a source of electricity. The use of biomass as an additional material for fuel in power plant has been widely carried out. This method is more commonly known as cofiring. Analysis of the cofiring combustion system of biomass in the boiler needs to be carried out in order to determine the characteristics of the combustion system that occurs. By varying the composition of the fuel, an analysis of the energy produced from the combustion reaction will be calculated. In this study, the comparison of the use of coal and wood bark was varied at conditions 80:20, 70:30, 60:40, 50:50, 40:60, 30:70, 20:80. Assuming that the steam rate and temperature conditions to be achieved from the combustion products are constant. From the results of the analysis it was found that an increase in the amount of cofiring bark resulted in a decrease in the heating value of the combustion reaction and an increase in fuel capacity. Thus, it can be concluded that the use of bark cofiring in boilers with a coal design is less effective because it will require additional energy to increase the fuel consumption rate and reduce combustion efficiency due to not achieving optimal combustion energy because the initial design combustion chamber capacity is fixed.

Abstract

The dual fuel line 2 100MW steam power plant (PLTU) is one of the power plants owned by PT Riau Andalan Pulp and Paper. To produce steam PLTU line 2, PT RAPP used biomass as the main fuel and natural gas as an alternative fuel to achieve the required steam production target. The combination of exergy analysis (second law of thermodinamics) with economic analysis is exergoeconomic. With this exergoeconomic analysis the value of losses in each component of the steam power plant is more noticeable because it is already in the value of the currency. By carrying out this research the value of the cost of loss can be identified specifically, from the highest loss to the lowest loss. At the dual fuel line 2 PT RAPP 100MW steam power plant the biggest cost of the loss was at the boiler at US$ 533.048,48/hour, followed by the HP pre-heater 2 for US$ 262.869,97/hour, the HP pre-heater 1 for US$ 83.153,52/hour, condenser US$44.063,03/hour, pump 2 US$42.846,85/hour, feedwater tank US$34.849,08/hour, steam turbine US$234.05/hour and the smallest was pump 1 US$71,48/hour. With a total value of a loss of US$ 1.011.509,52/hour. Through this research, it was expected that the value of the cost of losses due to exergy destruction can be reduced.

Abstract

Indonesia is a maritime country that has an abundance of marine catches. In 2022, the production of marine catches reached 24.85 millions tons, while the export amount was 1.221 millions tons. This is due to the limited technology that can extend the freshness of marine catches. Based on this problem, a cooling system was designed in the form of an ABF that can freeze marine catch products. The Air Blast Freezing (ABF) system is designed at an air temperature of -40oC using a cascade refrigeration system. The working fluid used is R290/R32 hydrocarbon, which has very low GWP and ODP so it is safe for the environment and the earth's ozone layer. The results obtained show that the cooling load is 444.037 Watts, the LTC compressor power and HTC compressor power are 116.19 Watts and 205.98 watts. The designed air blast freezing system has a surface area of LTC evaporator of 2.670 m2 and HTC condenser of 4.780 m2. The calculated capillary pipe length is 1.94 m for HTC and 1.51 m for LTC, the COP of the ABF system is 2.774.
