      Gas turbine is a kind of internal combustion power machine, which uses continuous flow gas as working medium to drive the impeller to rotate at high speed and change the energy of fuel into useful work. The structure of gas turbine is the simplest, and it can embody a series of advantages, such as small volume, light weight, fast start-up, less or no cooling water.In the main flow of air and gas, the gas turbine cycle consists of compressor, combustor and gas turbine, which is called simple cycle. Most gas turbines use simple cycle.The compressor sucks air from the outside atmosphere and compresses it step by step through an axial-flow compressor to make it pressurized, and the air temperature increases accordingly; the compressed air is pressed into the combustor and mixed with the fuel i...

      Turbofan engine, also known as 'turbofan engine'. A gas turbine engine is a gas turbine engine which is ejected from a nozzle and ejected from a fan to produce reaction thrust. It consists of a compressor, a combustion chamber, a turbo (driven compressor), a low pressure turbine (driven fan) and an exhaust system. The first three parts are called 'core engines'. The available energy in the gas from the core engine is used to drive the low-pressure turbine to drive the fan, and the gas from the nozzle is used to accelerate the emission. Culvert ratio is closely related to fuel consumption rate. The first generation of turbofan engines appeared in the late 1950s, the bypass ratio, the compressor turbocharging ratio and the gas temperature in front of the turbine were relative...

'At present, China's gas turbine market competition is fierce, the past business model is no longer applicable, the future should be a new machine + localized service model to respond to China's energy transformation period of market demand. Only by thoroughly localizing the supply chain, technical service personnel and spare parts, can we quickly respond to customer needs to help power plants reduce operating costs and maximize revenue. 'Yao Zhenguo, Executive Vice President of Siemens (China) Co., Ltd., General Manager of Power and Natural Gas Group Greater China, is in Yixin...

Turbofan engine is a kind of aircraft engine, which is developed from Turbojet. Compared with turbojet, the main feature is that the primary compressor has a much larger area and is used as an air propeller (fan), pushing partially inhaled air back through the periphery of the jet engine.The air passing through the core part of the engine is called the inner passage, and the outer passage is called the outer passage only when the fan air passes through the outer part of the core engine. Turbofan engines are best suited for speeds between 400 and 1,000 kilometers, so most aircraft engines now u...
