High Pressure Fired Heater For Heat Recovery Steam Generator HRSG ASTM A213

Fired Heater for Heat Recovery Steam Generator (HRSG) application

The high pressure superheaters are of finned tube design and arranged for efficient heat transfer. Steam side pressure drop is minimized, but be sufficient to achieve good steam flow distributions.
The high pressure superheaters tube banks are interspersed in a series configuration as shown on the flow diagram so that all of the exhaust gas flows through the high pressure superheater.

• High Energy Efficiency
  • Waste Heat Utilization: HRSG allows for the recovery of waste heat from the exhaust gases of gas turbines or other heat - generating processes. This otherwise wasted heat is used to produce steam, which can then be used to drive a steam turbine and generate additional electricity. By capturing and utilizing this waste heat, HRSG significantly increases the overall efficiency of the power generation process. For example, in a combined - cycle power plant, the use of HRSG can increase the overall efficiency from around 40% - 45% for a simple - cycle gas turbine plant to 55% - 60% or even higher.
  • Cogeneration Capability: In addition to electricity generation, HRSG can also be used for cogeneration applications. The steam produced by the HRSG can be used for industrial processes, heating buildings, or other thermal applications. This combined production of electricity and useful heat further enhances the energy efficiency of the system and reduces the need for separate heat - generating equipment.
• Environmental Benefits
  • Reduced Fuel Consumption: Due to its ability to recover waste heat and increase energy efficiency, HRSG reduces the amount of fuel required to produce a given amount of electricity. This, in turn, leads to a decrease in greenhouse gas emissions, such as carbon dioxide (CO₂), sulfur dioxide (SO₂), and nitrogen oxides (NOₓ). For example, a power plant equipped with an HRSG may consume 15% - 20% less fuel compared to a plant without heat recovery, resulting in a significant reduction in emissions.
  • Lower Emissions: The improved efficiency of HRSG - equipped power plants also means that less fuel is burned, which leads to lower emissions of pollutants per unit of electricity generated. This helps power plants meet increasingly stringent environmental regulations and reduces the environmental impact of power generation.
• Operational Flexibility
  • Load - Following Capability: HRSG can quickly respond to changes in electricity demand by adjusting the steam production rate. This is achieved by varying the amount of heat recovered from the exhaust gases, which can be controlled by adjusting the flow rate of the cooling water or the position of the dampers in the HRSG. As a result, power plants with HRSG are better able to follow the daily and seasonal variations in electricity demand, providing a more stable and reliable power supply.
  • Combined - Cycle Operation: HRSG enables the integration of gas turbines and steam turbines in a combined - cycle configuration. This allows for more efficient power generation by utilizing the different operating characteristics of the two types of turbines. The gas turbine can provide quick - start and high - efficiency operation at partial loads, while the steam turbine can operate efficiently at full load. The combination of the two turbines, with the help of HRSG, offers a flexible and efficient power generation solution for a variety of applications.
