Xi 'an stone big energy engineering technology co., LTD. (hereinafter referred to as the stone big energy) is a new technology research and development, the application of joint-stock enterprises. Founded in October 2006, the registered capital of 20 million yuan, from 2006 only has 20 employees, annual output value 790000 yuan to 790000 existing staff 300 people, an annual output value 15 million yuan, achieved a leap-forward development.

The development of large stone period can be summarized as the following:

Initial stage (2006 ~ 2007)

Technical problems such as oil field, refinery industry, stone big energy and xi 'an petroleum university professor, CPC changqing petrochemical, professor, senior engineer, carried on the thorough investigation, and solved many problems. In order to better serve the society, to set up operations.

Growth period (2007 ~ 2010)

Stone big energy after the establishment, the company with technology as the leading factor, for oil field exploration, geological analysis to do a lot of work, at the same time for the oil refining, electric power, municipal, building materials industry provides the electrical, automation, debugging and other services.

Growing period (2010 ~ 2013)

Stone big energy in the new century for petroleum, chemical industry, metallurgy, building materials industries such as remaining heat and pressure to use r&d. Successful application of the waste heat drag turbine, pump; Waste heat power generation. For the special turbo (TRT, all kinds of tail gas turbine, the ORT turbine, steam turbine low parameters) of the research and development, design, manufacturing; Developed high efficient "NO compressor", "the ORC turbine", "yu molten slag recycling equipment, etc., respectively applied for national invention patents, with a number of core intellectual property rights.

FeiYueQi (2014 ~)

Great energy and ten years, more than for domestic manufacturers to provide technical services. With xi 'an jiaotong university, xi 'an petroleum university professor of scientific research team, set up research and development base. We solved the manufacturers remaining heat and pressure using and other technical difficulties. And designed for domestic more than 20 various types of steam turbine and a dozen types of expander, are running well, made great economic and social benefits. We at the same time, many enterprises of waste heat utilization system provides the design, construction, commissioning, operation, maintenance and other services. Cumulative use of remaining heat and pressure generating 574 million kW (h), managing BiaoMei 156 million tons, reduce CO2 emissions of 572 million tons. Implementation efficiency of 310 million yuan. Company after years of efforts, has become the industry well-known enterprises energy conservation and emissions reduction.
