The fan is designed to be installed on a column or other vertical structure. In addition, its oscillating function allows the air generated to radiate 100 ft. outward, The fan runs quietly and remains up and out of the way. A touch pad and dial controller allow adjustment of air speed, and the lightweight, low-profile cage protects the fan and workers.

China cow manure project to produce energy with biogas technology

Helping to alleviate China’s energy shortage, GE’s Jenbacher biogas engines will power the new Liaoning Huishan Cow Farm, which, once completed, will become the world’s largest biogas project based on cow manure.

The manure from the 250,000 cows at the Huishan farm, located in Shenyang, China, will be converted into biogas and is expected to produce 38,000 MWh a year through four GE JMS420 Jenbacher gas engines. The energy generated will be sold to the state grid in China.

One of the features of the project is
the use of fuel circulation. In addition to
the use of biogas for power generation,
the liquid (residual from biogas produc-
tion) will be used to nourish the grass
in the pasture, and the solid waste can
be sold as organic fertilizer, thus the
surrounding land will become a base
for organic agriculture.
