feed heating

But legislators also added proposals that could exempt utilities that feed heating systems or use high-efficiency technologies for heating and cooling.

The condensate then discharged to a de-aerator extraction pump before passing to the main boiler feed pump and three high pressure feed heating stages.

There are three stages of H.P. feed heating with six heater shells arranged in parallel pairs, a de-aerator and three low pressure heaters.

Steam is bled from the main turbine H.P. exhaust to drive the main boiler feed pump turbine, which exhausts to the feed heating system to improve the overall cycle efficiency.
