Abstract

Abstract Pelton turbines are widely used for micro scale power plants, this research aims to study the performance of pelton turbines with blades from L bow paralon material used for power generation. The equipment used is a pelton turbine, turbine blade is made of paralon material with a width of 2.5 cm and a length of 8 cm and a height of 1.25 cm. runner diameter is 35 cm with a number of 8 blades and 16 blades. The study was carried out by varying the number of blades and the angle of blades and the flow rate with pump pressure with a slope angle of 750 and 900 and water pressure of 0.9 bar, 1.5 bar and 1.8 bar. To produce electricity, the turbine is connected to the alternator, the measurement of the power generated by the turbine is done by measuring the voltage and current generated by the generator. Pelton turbine with 8 blades with 1.8 bar pump pressure with 750 blades produces 7,343 watts of power with an efficiency of 87.18%, at an angle of 900 produces 7,06 watts of power and an efficiency of 89.11%. On the 16 blades with a pressure of 1.8 bar with an angle of 750 produces a power of 7.7418 watts with an efficiency of 91.98% and at a blade angle of 900 the power produced is 7.886 watts with an efficiency of 93.62%. So the greater the pump pressure and the greater the number of blades and blades, the greater the power and rotation of the turbine produced.

Abstract

Abstract Electrical energy is the main energy needed for electrical equipment. Electrical energy is energy that is very important for humans because electrical energy is currently one of the basic human needs. Current power plants rely heavily on fossil materials, while availability is dwindling, and an alternative energy is needed to get electricity, namely the Pelton turbine. This study aims to obtain water power, namely the Pelton turbine and to obtain efficiency, power, TSR and torque by varying the number of blades. The result is that for 9 blades the value of Cp max = 0.71, CT max = 0.95, TSR max = 2.68, max efficiency = 71%, power P turbine max = 4.08 watts. Whereas for the 12 Blade Pelton turbine, the result is that Cp max = 0.79, CT max = 1.38, TSR max = 2.74, max efficiency = 79%, turbine P power = 4.69 watts.

Abstract

The Darrieus turbine consists of one or more long darrieus blades that traces imaginary cylindrical forces such as screw threads. Darrieus aerfoil blades give a reaction force that can attract it faster than the fluid flow itself. This test is carried out irrgation streams Sengkuang Village South Seluma District where the flow rate of water 0,9 m/s. The results obtained in this study were Darrieus Turbine without guide angle at water flow velocity (v) 0,9 m/s, torque coefficient (CT) = 78.80, Turbine efficiency (nt) = 46.847 %, rotation (n) the turbine power (PT)= 43.565 watt. Darrieus turbine uses a steering angle 300 at the velocity of water velocity (v)= 0,9 m/s. the torque coefficient (CT)= 94.32. turbine efficiency (nt)= 27.575%, round 95 Rpm and turbine power (PT)= 43.565 watt. Darrieus Turbine uses 450 directed angle at water flow velocty (v)= 0.9 m/s, torque coefficient (CT)= 95.52, turbine efficiency (nt) = 80.583%, round (n) = 105 Rpm and Turbine Power (PT)=43.565 Watt.

Abstract

Abstract Advances in technology in the industrial era now must be followed by developments that are more effective and efficient. Likewise, the problems that occur in each industrial production process, one of which is the production of palm oil processing (CPO). The problem that occurs is the presence of waste that requires special handling. There are several wastes generated from the processing of oil palm, one of which is the waste of mud and waste of boiler fuel ash. Waste sludge and ash from boiler fuel can be used to become an organic fertilizer. In the process of making fertilizer, it requires tools to make the production process effective and efficient. Hummer mill is a crushing machine for the process of making fertilizers, fertilizer ingredients that are mixed and fermented must be destroyed so that the process of continuing organic fertilizer materials is evenly distributed. Planning a Hummer mill engine design is planned according to needs begins with data collection machine functions so that designing (drawing) engine design and determine some metal materials. Considerations determining the material in accordance with the design and capacity that has been determined and needed. Based on the results of the discussion, the material used is shaft material, iron plate, unp iron, bearing, electro motor, pulley and V-belt as well as filter iron plate. The Hummer mill engine design is designed according to the needs and functions of the final destination of a fertilizer manufacturing process.
