Abstract:

Heat recovery steam generators are important equipment at district cooling plants. The capability of heat recovery steam generators in generating steam influences the steam absorption chiller’s performance. The steam generation capability of the heat recovery steam generators in turn is linked to the values of pinch point and approach point. Hence, a study on the pinch point and approach point for the heat recovery steam generators would be useful in understanding the effects of varying pinch point and approach point values to the heat recovery steam generators’ performance.

Abstract:

Combined cycle power plants play an important role in the present energy sector. The main challenge in designing a combined cycle power plant is proper utilization of gas turbine exhaust heat in the steam cycle in order to achieve optimum steam turbine output. Most of the combined cycle developers focused on the gas turbine output and neglected the role of the heat recovery steam generator which strongly affects the overall performance of the combined cycle power plant. The present paper is aimed at optimal utilization of the flue gas recovery heat with different heat recovery steam generator

Boilers are widely used in industries to produce steam. In some sectors, the steam generated is utilized directly in the production line for heating. Certain industries use steam to produce electricity. Fire tube boilers are limited to generating steam for processing; meanwhile, water tube boilers are widely used in electricity generation besides steam generation for processing lines. Subcritical boilers, supercritical boilers, and Heat Recovery Steam Generator (HRSG) are types of boilers commonly used to produce high capacity steam.

In installations where a gas turbine is coupled to a steam prime mover through an exhaust heat steam generator, the need may arise to estimate the behaviour of the latter away from its specified design conditions. For example, the performance of the steam generator when the gas turbine is operating away from its design conditions may be of fundamental importance in relation to the economics of a proposed coupled installation. In particular, it determines inter alia the extent to which supplementary firing may be required. A question closely related to that of the off-design performance of a gi

Abstract:

The working principle of the combined cycle in the combined cycle power plant (CCPP) is to utilize a certain amount of waste heat in the gas turbine, which reaches temperatures of 1650°C, to generate steam in the steam turbine. Due to the high temperature of the exhaust gas in the gas turbine, a device is needed to recover this waste heat, known as a Heat Recovery Steam Generator (HRSG). Compared to conventional HRSG, a once-through heat recovery steam generator (OTHRSG) offers the advantages of faster design time (25% faster than conventional) and lower design costs because it does not requir

Abstract:

Fossil fuel power plants, as combined cycle plants (CCGT), will increasingly have to shift their role from providing base-load power to providing fluctuating back-up power to control and stabilize the grid, but they also have to be able to run at the highest possible efficiency. Combined Heat and Power generation could be a smart solution to overcome the flexibility required to a modern power plant, this work investigates different layout possibilities allowing to increase the overall efficiency through the heat recover from the hot flue gasses after the heat recovery steam generator (HRSG) of

Abstract Calculations of the characteristics concerning the heat exchange equipment of the Flash/ORC power plant for the usage in waste heat recovery (WHR) cogeneration plants are presented. The use of hybrid power plants with water steam and organic working fluids, on the one hand, leads to an increase in the mass of the heat exchange equipment, and on the other hand, it ensures the generation of electrical energy and heat at high temperatures of the heat source, when the use of high-temperature working fluids is limited their thermal stability (for example, the thermal stability of silaxanes

Abstract:

The gas-steam power plant combines a gas power plant and a steam power plant, where Heat Recovery Steam Generator (HRSG) is a unit for generating steam. The waste heat from this system is channelled to the chimney with a Thermoelectric Generator (TEG) module to generate electrical energy. TEG uses the waste heat from the thermal conduction process from the chimney wall, where the height, diameter, and velocity variables are considered for analysis. To optimize this analysis, we used dimensional analysis to get a laboratory-scale system, and the method used the matrix dimensionless of the balan

Abstract:

Steam power plants have been extensively used in Iran for a long time, yet no specific step has been taken for promoting their performance. In this regard, full repowering is considered as a way to enhance the performance of steam power plants. Furthermore, because of the continental condition of Iran, duct burners can be used as a common strategy to compensate for power generation shortage caused by environmental conditions. In this study, the effect of using a duct burner on the full repowering of Be?sat Steam Cycle representing both single-and dual-pressure cycles was investigated based on

Abstract:

Approximately, 20%-50% of the total energy consumption during cement production is disposed of unintendedly as waste heat. This is very unfortunate considering that this waste heat still has the energy that can be further utilized. The heat recovery steam generator (HRSG) boiler system is one of widely used solutions in the chemical industry process to save operating costs in the chemical industry process. The purpose of this research is to determine the amount of energy that can be saved by implementing the HRSG system under ideal operating conditions. Based on the simulation results, the HRS

Abstract:

Flue gas from gas turbines at Nhon Trach 1 and Nhon Trach 2 gas power plant are in the temperature range of 100 - 113oC after heat has been recovered at the heat recovery steam generator. These heat flows are not recovered by conventional methods since they are not effective. Meanwhile, the organic Rankine cycle (ORC) uses organic fluids with low boiling point, that is why it can recover heat from low-temperature flue gas streams. Results of the ORC investigation reveal that with R245fa as a fluid, the Nhon Trach 1’s capacity will increase by 2.0 MW, and the Nhon Trach 2’s capacity will see an

Abstract:

High-pressure direct-fired steam-gas generator (HDSG) is to produce multiplex thermal fluid (contains water, CO2, N2 etc.) through efficient direct-contact heat transfer, which would utilize the flue gas heat and reduce the gas emission caused by ordinary boiler. Furthermore, the multiplex thermal fluid can promote the heavy oil recovery by both steam flooding and miscible flooding. This paper introduced three kinds of HDSG: pressurized submerged combustion vaporization (PSCV), multiplex thermal fluid generator and supercritical hydrothermal combustor, which are different in work pressure and
