E-class heavy-duty gas turbine AE94.2 and AE94.2K/KS
AE94.2, also known as E-class gas turbine, is widely used in natural gas power generation markets both domestically and internationally. It has the advantages of high reliability, durability, and high output performance. Due to its unique cylindrical combustion chamber structure, it can adapt to various special fuels, including light oil, some heavy oil, blast furnace gas, coke oven gas, etc., and has been favored by many dual fuel demand users in domestic and foreign markets. Structurally, the AE94.2 gas turbine adopts a horizontal split structure cylinder and a center pull rod rotor. The compressor consists of 16 stages of axial flow, 1 stage of adjustable stator blades, and the first 6 stages of compressor blades are coated with anti-corrosion coatings. The turbine is a 4-stage axial flow turbine, and the combustion chamber adopts two cylindrical combustion chambers distributed on both sides of the body, with 8 burners distributed on the upper part of each combustion chamber. The conventional loading rate of AE94.2 is 11MW/min, and when participating in grid peak shaving, it is 30MW/min. It has the characteristics of fast and flexible start stop.
Gas turbines play an unparalleled role in today's power generation field due to their cleanliness, environmental friendliness, speed, and flexibility. The three main gas turbines are AE94.3A, AE94.2 (or AE94.2K/KS), and AE64.3A, all of which have many characteristics such as cleanliness, efficiency, and flexibility, bringing customers diverse options and efficient economic benefits.
The AE94.2 series gas turbine has the characteristics of streamlined structure, high efficiency and reliability, easy maintenance, strong adaptability, stable and reliable performance, and excellent environment. The main technical advantages are as follows:
1) Structural features: Adopting a 16 stage high flow axial compressor, equipped with a single-stage inlet adjustable guide vane, 2 unique cylindrical combustion chambers, 2X8 low NOx burners, and 4-stage high-efficiency long-life turbine blades;
2) Easy to maintain: The rotor is a center pull rod rotor with high torque, high stiffness, and self centering, which can be inspected on-site;
3) Efficient and reliable: equipped with efficient and reliable secondary air systems, rotor displacement (RDS) systems, etc;
4) Strong adaptability: AE94.2K/KS gas turbine, LHV>3MJ/Nm3 can be utilized;
5) Quick start stop: Complete within 30 minutes from ignition to full load;
6) The gas turbine is shipped as a whole, with highly integrated auxiliary systems
