China's first 500kw. low concentration gas generating unit recently passed the review by experts. The new technology developed by Shengdong Group of Shandong Province fills the blank of low-concentration gas generating unit in China.

The successfully developed generating unit uses low-concentration gas. Under normal conditions, only gas with a concentration of above 25 % can be used to generate electricity. Concentration below this lower limit can easily lead to explosion. By installing several explosion-proof devices in the gas transmitting system, Shengdong Group extends the gas utilizing range by 20 percentage points, which means that as long as the gas concentration is above 5%, the electricity generating process is safe.
