high pressure steam produced by . a boiler or heat recovery steam generator (HRSG). Unlike gas turbines or microturbines, steam turbines do not directly consume fuel. Rather, the fuel driving the process is the fired boiler or plant equipment that produces heat for the HRSG (e.g., a gas turbine). Table 1. Summary of Steam Turbine Attributes for CHP

Cycle Chemistry –Why is it important? "It is clear that the major Boiler/HRSG failure mechanisms are driven by thermal and/or cycle chemistry influences" (EPRI, 2003) Effective cycle chemistry monitoring and control is required to: Operate plant safely. Protect plant integrity. Meet legal requirements, e.g. PSSR. Maintain reliability and availability.

Blowdown control. Boiler blowdown is the removal of water from a boiler. Its purpose is to control boiler water parameters within prescribed limits to minimize scale, corrosion, carryover, and other specific problems. Blowdown is also used to remove suspended solids present in the system. These solids are caused by feedwater contamination, by

As a starting point for specifiers, Gdaniec suggests a single-pressure HRSG to serve GTs rated up to about 20-25 MW. "You can comfortably produce steam in the 650F to 700F range with such a boiler," he adds. Dual-pressure HRSGs probably make most sense when the GT is in the LM6000 class of machines.
