Design And Research Of The Yukun Combined Cooling Heating And Power System Based On Gas Turbine

As the development of the world’s economy the energy consumption is increased. Many industries took related measures to increase the use ratio and decrease the output faced with the tendency of energy price up. No exception for shipping industry. It brings huge interest to the nation; meanwhile, consumes a great deal of energy. The fuel fee took more than half of the total expenditure of shipping. However, only small part of fuel energy can be taken into usage, most of that is given out which is a great waste. Gas turbine’s combined cooling heating and power system as the main integrated form of distributed supply system has the advantages of energy high-usage ratio, applying multi-fuel, environmental protection and etc. which enjoy the mainstream of nowadays energy development direction.This thesis applies distributed supply system’s combined cooling heating and power system into ship energy supply system to discuss and evaluate its technical economy and economy. First, taking "Yukun", Dalian Maritime University’s teaching and practice ship, as an example and researching its anchor condition, separately calculating the target’s cooling, heating and electric load according to ship load calculation rules:heating load 475kW, air conditioning load 520kW, power load 362kW, Domestic Hot Water load and preheat load for fuel oil and lubricating oil 562kW. Based on the results, the author designs two sets of gas turbine’s combined cooling heating and power system and makes choice for them. Then to evaluate each system on the analysis of the original energy supply system and the two sets of combined cooling heating and power system’s economy and thermal economy. After comprehensive assessing, The second project is superior to other project in Economy and thermal economy’s performance.The first part of this thesis’s last chapter gas turbine combined cooling heating and power system’s thermodynamic process. The following part makes mathematical modeling, edits combined cooling heating and power system’s calculation process and draws relation diagram of gas turbine’s performance and combined cooling heating and power system’s output energy. And then to discuss the influence of gas turbine’s pressure ratio, temperature ratio for the whole combined cooling heating and power system.
