Abstract

This research aims to calculate the amount of fuel in the multi-fuel boiler unit at PT Toba Pulp Lestari, Tbk. A boiler is a closed steam boiler, and the heat of combustion is transmitted to the water until it becomes hot steaming water or steam. In the work process, it is necessary to calculate the total fired and moisture to determine the efficient level of maturity for each unit. In this research, the author found that the energy needed to evaporate water in fuel up to 0% was Palm Caul 2303.67 kcal/kg, Palm Shell 3833.25 kcal/kg, and Bark 1513.69 kcal/kg. The energy used in the Multi Fuel Boiler requires Palm Caul 186,688.4 kg/hour, Palm sheel 97,683.6 kg/hour, and Bark 181,508.9 kg/hour.

Abstract

PT. KPBN Belawan is a company branch entrusted as an agent for buying and selling CPO (Crude Palm Oil). PT. KPBN Belawan operates a tank storage unit that temporarily stores CPO before selling it to customers. Regular inspections are necessary for the storage tanks, such as checking the thickness of the tank plates and ensuring the strength of the locking mechanisms on the shell central hole to prevent leaks during filling. This research aims to calculate the dimensions of the bottom cover of the storage tank (central hole), which serves as a seal for the CPO in a storage tank with a capacity of 5,000 liters. The calculated dimensions for the shell central hole are as follows: the nominal diameter of the shell maintenance hole bolts is 17.5 mm, the flange width is 40.25 mm, the outer diameter of the flange shell maintenance hole is 913.6 mm, the bolt circle diameter of the flange shell central hole is 887 mm, the inner diameter of the flange shell central hole is 869.5 mm, the number of bolts is 24, the flange thickness is 18 mm, and the bolt spacing of the flange shell mainhole is 115.77 mm.
