Which type of HRSG boiler is more compact in structure and used in smaller plants?
Which type of HRSG boiler is more compact in structure and used in smaller plants?
The vertical boiler is more compact in structure and can be fit in smaller plants and even indoor facilities. The horizontal boiler is used mainly in larger plants. With our solution, you can produce steam that can be used in a process (cogeneration) or used to drive a steam turbine (combined cycle).
What is HRSG in power plant?
The heat recovery steam generator (HRSG) is a heat exchanger designed to recover the exhaust ‘waste’ heat from power generation plant prime movers, such as gas turbines or large reciprocating engines, thus improving overall energy efficiencies.
How does a horizontal once through HRSG work?
The Horizontal Once Through has the same basic arrangement as the Horizontal Drum, but eliminates the High Pressure Drum while using GE’s in-house OT technology to increase flexibility, efficiency and daily cycling capabilities. With vertical gas flowing across horizontal tubes, this HRSG type is ideal when site space is limited.
What are the different types of HRSG units?
These HRSG units are designed under our proprietary technology based on two design options: horizontal gas flow with natural circulation and vertical gas flow with assisted circulation. Most of the units have been successfully tested and entered into commercial operation during the last five years.
What’s the difference between horizontal and vertical steam generators?
Horizontal types require a 30 % larger footprint area. More expansion joints are required in horizontal units. Structural requirements are higher in vertical types. Horizontal types are more difficult for maintenance and inspections. Overall cost may be same in both types.
How many pressure levels does a HRSG use?
In larger units, for optimizing the performance of the HRSG, steam generation takes place in multi pressure circuits. The current optimum is to use three pressure levels. (Details in the next article)
