product description

Micro gas turbine:

Micro gas turbine refers to a newly developed small thermal engine with power within a few hundred kilowatts. The basic technical characteristics are the use of radial impeller machinery and regenerative circulation. The rotor speed is generally between 50000 ~ 120,000rpm. The overall structure is simple and compact Easy to move. Because of its structural characteristics and the application of a series of advanced technologies such as air bearings and high-speed motors, it has the advantages of long life, good expandability, low pollution emissions, and low maintenance rates. The supply market, the oil and gas field market, the biomass gas market, the coal-bed methane and blast furnace gas and other low-calorific value gas markets, the mobile vehicle and the military market have been increasingly widely used, gradually becoming the main development direction in distributed energy supply technology . At present, the company has successfully developed a 100 kW class model (E100 series) with completely independent intellectual property rights. The core components are 100% domestically produced. Compared with similar foreign products, it has a higher cost performance. It has entered the market application stage and filled domestic Gas turbine industrialization gap. At the same time, research and development of a series of micro-turbines is also underway. Among them, the 300 kW class model (E300 series) is undergoing overall machine performance debugging and will be put on the market in 2019; the 600 kW fuel class model (E600) has also completed product design and has started processing parts.



E100 gas turbine:

The E100 micro gas turbine uses a single-stage high-efficiency centrifugal compressor, a two-stage high-efficiency axial-flow turbine, and an external low-pollution combustion chamber. The rated speed is 51000rpm, the power generation is 110-135kW, and the power generation efficiency is 26%. The noise index reaches the international advanced level, and the price is only about 1/2 of the foreign unit under the same power level. At the same time, the core components of the E100 microturbine have been 100% domestically made, which is more convenient and cost-effective for later maintenance. At present, it has entered the stage of product demonstration and marketing, which has filled the gap in the domestic industrialization of micro-turbine engines. Subsequent upgrade models will use air bearing and high-speed motor technology, greatly reducing weight and volume, and performance will reach international leading levels .
