Either for gas turbines OR for internal combustion engines, for the sustainable renewable energy future of Mauritius, explain which fuel(s) can be used and explain the combustion process with the help of relevant equations and diagrams. Show clearly how sustainability is achieved
through the proper thermal engineering processes.
Only few information provided in the images.
Your team started by assessing the boiler and steam network. You gathered the following information:
The boiler operates at a pressure of 7 bar.
The AF ratio is adjusted manually.
The steam network is insulated, except at certain points where fittings and valves are present
No visible steam leaks.
The exhaust gas temperature is 330°C.
The O2 percentage in the exhaust was found to be 8.5%.
Maintenance is not regular.
The boiler consumed 23,000 GJ of natural gas in 2022 (price of natural gas is JD 7.5/GJ). Prepare a short note (to be incorporated in the audit report which your team leader will compile) to provide your assessment of the boiler and steam system. Your contribution should include the following:
1. Estimation of current boiler efficiency.
2. Measures that can be taken to improve the boiler efficiency.
Why renewable energy sources are called sustainable? List out any two reasons why they are considered environment friendly?

- Scenario: You are offered an apprenticeship at GE power company which has more than 125 years of integrating the latest innovations in electricity generation and its delivery including hybrid power technology. Nearly 1/3 of the electricity generated in the world uses GE equipment. GE's hybrid energy system portfolio can be customized and scaled for specific customer or system needs. Depending on the specific needs of a customer, GE can offer the following solutions for a full hybrid power generation system: • Hybrid power plant and grid feasibility studies - Determine the specific benefits a hybrid solution can provide • Hybrid power plant and equipment design – Customize the plant and equipment design to take full advantage of the hybrid components • Wind, hydro and solar forecasting via digital wind, digital hydro and digital solar farms - Evaluate the suitability of different forms of generation at a specific site • Hardware and software solutions - Combine the physical and digital…arrow_forwardWhat would be the likely steps needed to be taken to plan the research, funding, and installation of Hydrogen car Chargers in a big city?arrow_forwardAnswer question 2 based on the results of question 1. You have a natural gas furnace in your home that used 78,500 cubic feet of natural gas for heating last winter. Your neighbor has a furnace that burns heating oil, and used 516 gallons of heating oil last winter. You can convert the natural gas and heating oil consumption data into Btu to determine which home used more energy for heating. Natural gas BTU: 1,028 Btu per cubic foot Oil BTU: 138,590 Btu per gallon Natural Gas BTU= 80698000 Btu Oil BTU = 71512440 Btu The home that used a natural gas furnace used more energy for heating. 2. You need a new furnace for your home, and you are comparing systems that use natural gas and heating oil. One factor to consider is the cost of fuel. You can compare the price of the fuels on an equal basis by dividing the price per unit of the fuels by the Btu content per unit of the fuels to get a price per million Btu. Assume Natural gas price = $10.50 per thousand cubic…arrow_forward

The Tarraleah scheme redevelopment pre-feasibility study was undertaken through this initiative, with funding support from ARENA under the Advancing Renewables Program. For this assignment problem you will be using your knowledge of hydro power to: (1) estimate extended specifications for a new power station on the left bank of the Nive River opposite the existing power station; and (2) to reverse engineer specifications for the Pelton turbines currently installed at the Tarraleah power station. The pre-feasibility design team established basic parameters of a new power station to comprise two Francis turbines with a design flow of 20 m³/s (total 40 m³/s), a net head of 305 m and an installed capacity of ~57 MW (total 113 MW).

- View Policies Current Attempt in Progress A High-Performance Engine. You and your team are tasked with evaluating the parameters of a high-performance engine. The engine compresses the fuel-air mixture in the cylinder to make it ignite rather than igniting it with a spark plug (this is how diesel engines operate). You are given the compression ratio for the cylinders in the engine, which is the ratio of the initial volume of the cylinder (before the piston compresses the gas) to the final volume of the cylinder (after the gas is compressed): VV, Assume that the fuel-gas mixture enters the cylinder at a temperature of 26.0 °C, and that the gas behaves like an ideal gas with y-7/5. (a) If the compression ratio is 14.9:1, what is the final temperature of the gas if the compression is adiabatic?
