These books are the most comprehensive technical treatments of the design and operation of large power steam turbines available today. Characteristic types.

Introduction A steam turbine can be defined as a form of heat engine in which the energy of the steam is transformed into kinetic energy by expansion through nozzles, and the kinetic energy of resulting jet is in turn converted into force on rings of blades mounted on a rotating disc.

Steam micro-turbines are considered to be such devices which produce output power of the order of a few kWs. Steam turbines on micro-power plants are capable of delivering electric power ranging 1 - 6 kW [1]. For optimal electricity production, a thermal power plant TPP is chosen to encompass effective and robust choice of facilities.

The turbine and the alternator are facilities of importance in the constitution of a TPP [2]. The ability of turbine to generate a rotary motion made it suitable to drive an electrical generator. In the search for an alternative source of energy, palm kernel shell was found to be a well-known biomass product because of its higher heat energy or calorific value.

Palm kernel shell has gained it status as a biofuel resource for biomass product which is cheap, readily available and due to its high calorific value, its properties can be utilized in creation of an efficient micro-power plant which comprises of five main components which are the boiler, turbine, generator, condenser and pump.

It is therefore beneficial to produce high pressure steam, and let it expand to the desired pressure and temperature through a turbine or to extract part of the steam from the turbine before it reaches the low-pressure stage and its rotary motion is used to drive the generator to produce electricity. The aim of this research is to conduct a design analysis for an efficient steam turbine for a palm kernel shell PKS fuelled micro power plant which will generate 5 kW electricity.

Description

The specific objectives of this research are to: design and analyze a steam turbine based on predetermined design considerations and materials selection criteria; and evaluate the performance of the steam turbine in propelling the generator to produce 5 kW of electricity.

The design analysis has formed a baseline for the development of a steam turbine with target of producing 5 kW of electricity in micro power plant using PKS as fuel.

The research is limited to design, simulation and analysis of the rotor, blades and nozzle of the steam turbine. Palm kernel shell PKS is the main by-product of palm kernel oil production. Palm kernel is kernel from oil palm fruit. After the oil palm fruit went through the palm oil process, the kernels are separated and kernel oils distilled [3]. Oladosu and Oladosu et al. The outcome supported the use of PKS for power generation because of its higher heating value, but the study failed to implement same.

Oladosu et al. By way of backward calculation approach, standard design equations were used to size furnace, Turbine and other components.

The results showed that to generate 5 kW of electricity from palm kernel shell, 5. This is the area this study attempted to address. Chandra et al. Further analysis based on thermal and structural distribution on blades was carried out [11].

Chenduran [12] analyzed, in blade design, stress failures, efficiency and nozzle angle using solidworks software. Many designs have been carried out on turbines ranging from single-stage axial-flow turbines, two-stage axial-flow turbines, radial-flow turbines to radial-axial-flow turbines [1] , efforts in the area of micro-turbine design for micro-power plant have been scanty.

This is the germane area in which this study is posed to contribute. Materials and Methods 2.

Advances in Steam Turbines for Modern Power Plants

Design Concepts In the design of a steam micro-turbine, there are major parameters to be considered. The input parameters included the superheated steam temperature, pressure, mass flow rate and other specific properties. The required output to achieve necessary power supply required are the angular velocity, speed, and torque. Others include the type of cycle for effective conversion, the classification of the steam turbine, the blade profile design and arrangement, the number of stages required for effective steam pressure utilization, nozzle and condenser design.

The turbine design process has a series of steps as enumerated in Figure 1. Determination of staging based on the turbine specifications; the turbine designer makes some basic decisions on which the flow path design is built, such as degree of reaction, desired blade peripheral speed, stage diameters, and number of stages in the turbine.

At this stage, the number of rows of stationary and moving blades is established.

Determination of optimum flow passage angles by creating velocity diagrams for each stage based on the mean diameter of the flow path to determine appropriate airfoil entrance and exit angles, for best performance at the design. Detailed stage design determines the quantity and the size that is the width or chord of the blades short constant section airfoils or a series of radial stations for tall blades with twisted airfoil shapes.

Reliability evaluation ensures that steady steam bending and centrifugal forces are within acceptable limits. The vibratory characteristics of the blades are predicted and compared with the frequency and shape of unsteady forces from a variety of sources that acted on the blades.

Steam turbine depends completely upon the dynamic action of the steam. Singh has been involved in developing and teaching application of lifing strategy to many mechanical components, this includes hcf, lcf, creep, fracture mechanics.
