Abstract

Abstract A steam boiler is a device used to process water into steam with a planned temperature and pressure. Then the steam which has that pressure is flowed into a process. Broadly speaking, the way the boiler works, hot steam that comes out of the fire is absorbed by the boiler wall (heating field). Process of processing palm oil at CPO (Crude Palm Oil) mills Through the process of boiling palm kernels with the help of a much needed tool, namely a steam boiler. A steam boiler is a device that works by heating water to boil and producing hot steam with high pressure, the resulting heat energy or what is often called heat is absorbed by the boiler wall (heating field), then it can be used for boiling coconut ore processes palm.

Abstract

Abstract Steam boilers are devices that work by heating water to boiling and producing high-pressure hot steam, heat energy or often called heat can be used for oil palm boiling processes at CPO mills. Heating Value is chemical energy released by fuel during the combustion process. Fuel value consists of two types, namely: Highest Heating Value (HHV) Low fuel value (Lowest Heating Value / LHV) Low fuel calorific value is the amount of heat obtained in perfect combustion of 1kg of fuel without taking into account the heat condensation of water vapor on the fuel.

Abstract

Exhaust emissions are waste products of fuel combustion from inside the machine issued through the exhaust system. Premium fuel is a fuel consisting of a mixture of hydrocarbon liquid are very volatile which has an octane rating of 88 ron. Premium is the product Pertamina which contains C2H6- C6H14 with a minimum content of sulfur (S) 0.05%, Lead (Pb) 0.0013%, and oxygen (O) of 2.7%. Motor fuel is such a machine types of calories that converts chemical energy of fuel into mechanical energy

Abstract

Abstract Palm oil processing plants (CPO) in the process really need the role of a steam boiler. A steam boiler is a device that works by heating water to a boil and producing steam. A steam boiler basically consists of a drum that is closed on both sides, with a to hold water. The classification of the steam boiler can be based on the fluid flowing in the pipe, its use, the location of the kitchen, the location of the pipe, the water circulation system, and the boiler heat source. This water in the drum is not only used to get steam heating, it is also useful to prevent the temperature rise that is too high from the parts that are directly related to the flue gas. Theoretically, to get steam with a capacity of 43 tons/hour and a pressure of 28 kg/cm2, the area of the drum pipe A = 28.26 m², the thickness of the drum plate T = 0.875 cm, the stress that arises in the transverse direction = 1184.05 kg /cm² In planning the allowable stress is 2400 kg/cm², and the calculation results are 1184.05 kg/cm². So this plan meets the requirements that t is 2400 kg/cm² 1184.05 kg/cm². Inspection that the drum does not break 0.875cm 0.4 Meets the requirements that the drum is not easily broken

Abstract

Abstract Air pollution is a major threat to humans, which results from motor vehicle fumes. Each combustion process will produce dangerous exhaust gas products that have a negative impact on human health and the environment, if the composition is above the threshold. One of the exhaust gas content is CO gas (Carbon Mono Oxide). Two methods can be used to reduce motor vehicle emissions, namely: First, by increasing knowledge about the selection of fuel (HC), the second provides further treatment of vehicles by periodic maintenance of the motor vehicle.

Abstract

Abstract The oil palm processing industry in CPO mills really needs the role of a boiler, where the working process of a boiler is by heating water to boiling and producing high-pressure hot steam. Based on the fluid flowing in the pipe there are two kinds of boilers, fire tube boiler and water tube boiler. The difference between the two lies in the resulting steam pressure where the water pipe steam boiler is higher than the fire pipe boiler

Abstract

A steam boiler is a device that works by heating water to a boil to produce high pressure hot steam. The drum is made of forged steel DIN 17100, St 37-1 with a tensile strength of 240 N / mm² = 240 kg / cm². In the palm oil processing industry CPO (Crude Palm Oil) the hot steam produced by the steam boiler is used to drive steam turbines, as source of electrical energy, oil palm boiling, and other palm oil processing processes.The economizer is part of a steam boiler which serves to heat water for filling the kettle so that it reaches its boiling point.
