waste heat boiler and hrsg,heat recovery steam

2019-4-8·A heat recovery steam generator (HRSG) is an energy recovery heat exchanger that recovers heat from a hot gas stream. It produces steam that can be used in a process (cogeneration) or used to drive a steam turbine (combined cycle). The term HRSG refers to the waste heat boiler in a Combined Cycle Power Plant.

heat recovery steam generator - an overview

The heat recovery steam generator (HRSG) in a natural gas combined cycle (NGCC) plant may provide a viable disposition route for the reclaimer waste. For example, in the United States, a gas turbine-powered petrochemical plant has used a supplementary firing in the HRSG

Types of Heat Recovery Steam Generators (HRSG)

Normally HRSGs do not have any additional heat input. The performance and output of the HRSG is dependent on the exhaust heat of the gas turbine. At part loads, this leads to reduced output from the HRSGs. In addition, ambient conditions also affect the Gas Turbine performance. This could affect the downstream process were the steam is used.

The small footprint makes it suitable for both onshore and offshore applications, like floating platforms. It is able to cope with lesser fuel quality. When required, the HRSG can be designed for dry-running capability. The gas turbine continues operation and can be shut down later, at any given moment.

HRSGs for small plants - Rentech Boilers

For a boiler producing saturated steam, half-load operation demands no special consideration. However, for a HRSG designed to produce superheated steam, the gas flow and temperature at reduced load might dictate a change in superheater arrangement, a different tube material, and revised thinking with respect to the superheater. Supplementary firing
