Abstract

The present invention relates to a small gas turbine engine generator apparatus, which is primarily employed in generation of backup power. The apparatus utilizes the high-efficiency and low-pollution features of the gas turbine in combination with an air compressor to provide a high-pressure air source to start up a turbine pressure booster, which is taken as the power kernel of the generator rotator. In addition, its burning room has a two stage design to burn out the fuel more completely, thereby reducing the environmental pollution. Modularized production allows the apparatus to replace the currently existing reciprocating piston generator due to small size and light weight of the machine. In addition, the vibration generated by the apparatus in operating is small and the restriction of the fundamental requirement for construction is low. Furthermore, it modularization design makes the generator convenient to maintain and repair, thereby greatly reducing the cost of establishment.

200412393 V. Description of the invention (5) Exhaust gas generated from the start-up to idle operation of the “Type” gas turbine generator device will not enter the power full wheel 1 1. One keeps the simplification of the start-up procedure and one facilitates the start-up of the unit. In addition, the fuel supply device 42 can be connected to the above-mentioned heat exchanger 24 in advance, and the fuel can be preheated first, and then connected to the first-stage combustion chamber 2 丨 1. The turbocharger 10 is mainly used for operation. The high-temperature waste heat gas discharged at that time passes through the role of the heat exchanger 24. When the fuel passes through the heat exchanger 24, it can be preheated to increase the temperature of the fuel. In addition, there is a heat exchanger 25, which is installed between the compressor 101 and the combustion system 21 of the turbocharger. The main purpose is to use the hot gas discharged from the power turbine to enter the heat parent and change to 25 to improve After the air temperature from the compressor 101 is introduced into the combustion chamber 21, the waste heat gas energy can be effectively used, and the power generation efficiency of the generator device is greatly improved. [Embodiment] ± Please refer to "Figure 1". When operating, the high-pressure air storage unit 31 first sends the air in the high-pressure air bottle 32 to the turbocharger 10 to push the blades of the turbine 102. Make the turbocharger start to rotate, causing the compressor 101 of the turbocharger 10 to suck in the external air through the filter 103. When the speed reaches a preset value, the gas supply device 41 or fuel oil The supply device & starts to send fuel (gas or fuel) to the first stage combustion chamber 2 1 ^. After the successful ignition, the fuel flow is gradually increased to increase the turbocharger 10 speed to idle speed; the fuel is mainly The snoring sound is completed in the first-stage combustion chamber 211. At this time, the second-stage combustion chamber 212 is used to provide additional combustion space to reduce air pollution caused by incomplete combustion when the motor device is operating. At the same time, X is also 200412393. V. Invention Explanation (6) Therefore, it can accelerate the time for the generator unit to reach idle speed. It mainly uses the hot gas discharged from the power turbine 11 to enter the heat exchanger 2 5 ′, and the hot gas and the air introduced from the compressor 101 enter the heat exchanger 25 to raise the temperature of the air introduced from the compressor 101. Referring to the figure, when the turbocharger 10 is started to idle, the high-temperature waste heat generated by the turbocharger 10 can be guided into the heat exchanger 2 4 ′ through the three-way valve 27 to heat the heat exchanger 2. 4, and then introduce the heat exchanger 25 to preheat it. When the heat exchanger 25 is heated to a certain value, the so-called load mode can be started. The main purpose of this program is to preheat the heat exchangers (24, 25) at the same time as the generator unit is started. In addition, it also simplifies the startup process. In other words, the power turbine 11 does not run during the startup. Another feature of this start-up procedure is the operation of the three-way valve 27. When the unit is running under load, the high-temperature hot gas exhausted from the full wheel 102 will enter the power turbine first to generate electricity and then enter the heat exchanger 24. This design is to avoid excessive pressure loss caused by preheating the fuel, which will reduce the power generation efficiency and cause an outweighing effect. In order to allow the heat exchanger to quickly reach the operating temperature, during the generator device startup mode, the three links The valve 26 can send the high-pressure air passing through the compressor 101 directly into the combustion chamber 21 without passing through the heat exchanger.

When the generator unit runs into the load mode, the function of the first-stage combustion chamber 2 1 1 is similar to the mother fire (P i 1 〇tf 丨 丨, ^ occurs in the second-stage combustion chamber 212, fuel :) empty: two After the second material is burned, the chemical energy is converted into thermal energy after the process: the turbine 102 is transmitted, and the turbocharger 10 rotor is driven to rotate two degrees;

Description of the invention (7) _ The dynamic power turbine 11 can be achieved by the speed of the power turbine's speaking-speed rotor power generation technology or through traditional mode operation. ^ ^ ^ That is, the rotational kinetic energy is converted into electric energy through the transmission gear, and the required rotational speed of the motor is transmitted. A waste heat recovery device 2 9 can be installed, and the head 1 3 · 'In addition, as shown in the figure, Other heating applications, for example, the recovery of hot gas that generates more than 埶 1, can be used to understand from the above that the present invention constitutes steam; The combustion chamber can be mixed and burned in the stage combustion chamber when the turbocharger starts the? =: Remain time, ahead of the first first stage combustion chamber "= When in the 载 load mode operation, the main combustion space, this setting can change the ^ — stage combustion chamber into $ _ # + @ ^ ° In addition, the period from the start of the Syrian motor device to the load operation plate type was reduced to reduce the production due to incomplete combustion.
