A company that meets its electricity needs from the central grid and its thermal energy needs from coal is planning to make a new investment (natural gas motor cogeneration system) to reduce energy costs. Thanks to this investment, this firm's electricity and coal costs will be eliminated. The annual electricity and coal need is given in the table below according to the last digit of your Student Number (SN). The economic and technical information required for the current situation of the firm and for the establishment of a new cogeneration system are given separately in the tables below. The natural gas consumption required to generate 1 kWeh of electricity in the cogeneration system is obtained in the specific fuel consumption equation. The suitability of the new cogeneration system to be established will be determined by the following methods by using compound rate (for last digit of your Student Number less than 5 ) and real rate (for last digit of your Student Number equal to 5 and greater than 5) Descriptions; Cogeneration systems are the general name of energy conversion systems that produce electrical and heat energy simultaneously without using additional fuel. Energy saving is achieved by using the waste energy from electricity generation to meet the heat energy needs of the company. Internal consumption is the electrical energy that an electricity generation system consumes to generate electricity. Internal consumption rate is the ratio of the consumed electrical energy to the produced electrical energy You can make calculations using the Excel program. Systematically prepare the homework report by placing the excel tables and necessary explanations in the appropriate places. Specific fuel consumption = 3600 [m/kW.h) where; Hu = Lower heat value of fuel (kJ/m) ne = electrical efficiency of cogeneration system Hune Need to answer a. Determine the electrical power capacity (Ne [kW]) of the cogeneration system. b.
