The heat recovery steam generator (HRSG) provides the thermodynamic link between the gas turbines and steam turbines in a combined-cycle power plant. Each HRSG solution is custom-engineered to meet your desired operating flexibility and performance requirements.
1. Determine the desired operating pressure. For existing steam-use facilities, the operating pressure has typically been set in the past and now acts as a constraint on the system design at hand. For new facilities, slightly more flexibility exists and yet operating characteristics of equipment in the steam-use
In a reheat steam turbine, steam flow exits from a high-pressure section of the turbine and returns to the steam generation system where more superheat is added. The steam then goes back into an intermediate-pressure section of the steam turbine and continues its expansion.
Efficiency of a steam driven generator. The efficiency of a steam driven generator depends on many factors such as the type of steam turbine, its size, the inlet steam pressure and temperature, the exhaust steam pressure and temperature, and the steam flow rate. Steam turbines are suitable for large thermal power plants.
Pressure. Steam-injection pressures vary from field to field, depending on the: Reservoir requirement; Steam-injection rate; Tightness of the formation; A steam generator can be operated at a pressure of approximately 2,700 to 3,000 psig and can be designed specially for a higher operating pressure if required.

High temperatures in a sealed volume results in high pressure, which can be used to maximize efficiency and power. High pressure boilers have historically been misunderstood and were therefore considered dangerous; there are multiple recorded instances of exploding industrial steam engines or locomotives resulting in death and injury.
Steam Pressure Reduction: Opportunities and Issues Some of the main potential losses in a steam system are noted in Figure 1. Only the energy losses that can be reduced by lowering steam pressure will be discussed in this technical brief, and are listed below: • Steam leaks from high-pressure components (e.g. valves and piping)

They accomplish this by boiling water at subcritical pressures with intricate fuel systems. In some jurisdictions, the high pressure and high steam output capability of steam boilers requires a fully certified and licensed operator to be on-site in order to be operated. There are two common designs for a steam boiler: firetube and watertube.
Sussman MBA Packaged Electric Steam Generators. Small size, small capacity Sussman MBA Electric Steam Generators are perfect for industries that require efficient, high quality steam in laboratories, hospitals, computer rooms, pilot plants and for small, low-steam consuming loads.
As the high pressure steam comes out of the high pressure turbine losing its pressure to rotate the blades, its specific volume increases (Pressure decreases). So in order to handle fluid with high specific volume, low pressure turbine is made bigger in size.
A steam turbine is driven with 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.
Steam Piping Best Practices ... Use a flash steam recovery system to flash high pressure condensate to steam and then inject the steam into the low pressure steam system. ... For example, a 5 psi system should not have condensate lines higher than 10 feet above the steam trap. Properly Size Steam Trap Drip Leg Lines.
