To make electricity steam boilers produce hot high pressure
steam. The steam goes into steam
turbines which turn the alternators that actually make the electricity. The steam, cooler and lower pressure comes
out of the turbine. This waste steam is
too cool and too low pressure to feed into a turbine, but it is plenty hot
enough for space heating. Locate your
building close to an electric power station and you can heat it with waste
steam from the turbines. The electric
company will be glad to sell it to you at a good price.
For cogeneration to
be really effective, the electric power station has to be located downtown
where there are plenty of buildings needing heat. This works, electric power stations run
quietly, are not very big, and make fine neighbors. I used to own a triple decker in Cambridge
right off Western Ave. There was a nice power station right on Western
Ave.
For fossil fuel
plants cogeneration works fine. Nuclear
plants not so much. The greenies hate
nuclear power and put out all kinds of anti nuclear propaganda and run off
demonstrations at nuclear plants under construction. So we can skip nuclear plants for
cogeneration.
But we ought to
insist, thru our public utility commissions, that new fossil fuel electric
power stations be located downtown so that cogeneration is possible. It will save a good deal of fuel over the
years.
