GAS TURBINE EXHAUST SYSTEMS-HEAT RECOVERY STEAM GENERATOR

Baffles are vanes or panels utilized to direct the flow of exhaust gas, typically through the heated surfaces of a Heat Recovery Steam Generator (HRSG) / boiler (harps or modules). Our Aarding brand baffles are designed to minimize gas bypassing the harps or modules, and they maximize the exchange of heat in the harps or modules where steam …

Options for Improving the Efficiency of Heat Recovery

The low exhaust gas temperature from gas turbines, typically ranging from 900 to 1050F, generates less steam on unit gas mass basis in the HRSG evaporator compared to a package boiler. On the other hand, in a steam generator or package boiler, the flue gas stream is cooled from adiabatic combustion temperature of 3300 F and hence generates a

Combined Heat and Power (CHP) Level 1 Feasibility Analysis

Company A even without CHP. A wood boiler system without the steam turbine generator would generate about $8,500,000 in annual operating cost savings compared to the natural gas boiler baseline. Adding the steam turbine generator increases the annual savings by close to $800,000 at an estimated incremental capital cost of $3,500,000.

WASTE HEAT TO POWER SYSTEMS - EPA

Steam turbines are one of the oldest and most versatile prime mover technologies. Heat recovery boiler/steam turbine systems operate thermodynamically as a Rankine Cycle, as shown in Figure 2. In the steam Rankine cycle, the working fluid— water—is first pumped to elevated pressure before entering a heat recovery boiler.

Heat recovery steam generator - Wikipedia

A heat recovery steam generator (HRSG) is an energy recovery heat exchanger that recovers heat from a hot gas stream, such as a combustion turbine or other waste gas stream. It produces steam that can be used in a process ( cogeneration ) or used to drive a steam turbine ( combined cycle ).
