INCREASING THE ENERGY EFFICIENCY OF BOILER
2019-10-9 · Recent examples: A chemical plant is saving $500,000 per year by checking for, and replacing, all leaking steam traps. A plywood plant reduced its steam load by 2700 kg/h (6000 lb./h) by upgrading its piping insulation. Lowering the systems steam pressure or water temperature to what the involved processes actually need can also reduce energy consumption.

Combined Cycle Plant for Power Generation-
In a Flexicycle power plant, each combustion engine generator set has an associated HRSG. Bypass valves are used to control the admission of steam to the steam turbine when an engine set is not operating. One engine can be used to preheat all the HRSG exhaust gas boilers with steam to keep the HRSGs hot and enable fast starting.
