The video shows (3) different size expanded gas engines that were reconfigured
to run by consuming thermal energy created by steam. In this case, the
test factory had excess waste steam available to utilize. Therefore,
for this application the EG engine was modified to be powered by thermal
energy from steam. The largest of the three engines will turn a generator
that will produce 3.7 megawatts of electricity. The video was produced
to exhibit this particular waste steam application of the engine and
all the facts and figures given in the video are based on this particular
type of engine configuration.
It should be noted that the same engine can be configured to be powered
by thermal energy from the environment, by steam pressure, or by a certain
quantity of head pressure of any liquid passing through a pipe such
as a natural gas line, or water line. The engine can also be configured
as a PA engine which only needs water to run and is the best choice
when little thermal energy is available from the environment.
