Abstract:
Tri-sectional regenerative air heater is used widely because of its compactness and better performance. Study on the matching analytical calculation method of heat transfer is rarely carried out because of the complicated heat transfer process. This paper developed a model to solve the heat transfer calculation of multi-sectional regenerative air heaters, which usually have several layers. Then we designed the computational procedure to carry out the model. One example of a tri-sectional regenerative air heater with hot layer and cold layer shows the effectiveness of the algorithm, and the res

Abstract:
In this article, the performance of regenerative power plants in terms of second law of thermodynamics is discussed. The performance of the cycle is improved with the addition of backward cascaded-type and open-type feedwater heaters. This improvement is obtained by the reduction in irreversible losses as the number of feedwater heaters increases. A conventional energy-balance approach is used to calculate the irreversible losses in the cycle. The irreversible losses of each component of the cycle is given in a dimensionless ratio and from that ratio one can easily see the fraction of the irre

Abstract The paper presents an efficiency analysis of two transcritical CO2 power cycles with regenerative heaters. For the proposed cycles, calculations of thermal efficiency are given for selected values of operating parameters. It was assumed that the highest working temperature and pressure are in the range from 600 to 700 °C and 40 to 50 MPa, respectively. The purpose of the calculations was optimization of the pressure and mass flows in the regenerative heaters to achieve maximum cycle efficiency. It follows that for the assumed upper CO2 parameters, efficiency of 51-54% can be reached,

The transition from fossil generated energy towards regenerative energy sources is an important topic. Especially the generation from wind power plants and photovoltaic systems underlines the most important difference in comparison to conventional energy generation and distribution. One of the main characteristics of renewable energy sources is its decentralized generation, where existing distribution paths will become more and more a bottleneck in the future. The solution for this challenge is called smart grid and is driven by information, such as energy consumption, in order to match energy

Abstract Calculations were performed of the thermal system of a power plant with installed water pressure tanks. The maximum rise in the block electric power resulting from the shut-off of low-pressure regenerative heaters is determined. At that time, the boiler is fed with hot water from water pressure tanks acting as heat accumulators. Accumulation of hot water in water tanks is also proposed in the periods of the power unit small load.

Conventional concentrating solar power (CSP) plants typically have a very high levelised cost of electricity (LCOE) compared with coal-fired power stations. To generate 1 kWh of electrical energy from a conventional linear Fresnel CSP plant without a storage application, costs the utility approximately R3,08 (Salvatore, 2014), whereas it costs R0,711 to generate the same amount of energy by means of a highly efficient supercritical coal-fired power station, taking carbon tax into consideration. This high LCOE associated with linear Fresnel CSP technology is primarily due to the massive capital

Abstract:
Abstract Thermal power plants employ regenerative type air pre-heaters (APH) for recovering heat from the boiler flue gases. APH fouling occurs due to deposition of ash particles and products formed by reactions between leaked ammonia from the upstream selective catalytic reduction (SCR) unit and sulphur oxides (SOx) present in the flue gases. Fouling is strongly influenced by concentrations of ammonia and sulphur oxide as well as the flue gas temperature within APH. It increases the differential pressure across APH over time, ultimately leading to forced outages. Owing to lack of sensors with
