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:

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,

Abstract:

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

We have compared the regeneration of axons through frozen-thawed or heated muscle autografts in the sciatic nerve of adult rats. Our results have shown that axons regenerate through muscle grafts which had been either frozen-thawed or heated to 60°C prior to transplantation. However, axons failed to regenerate through muscle grafts which had been pre-heated to 80°C. We speculate that this difference may be related to the thermal lability of components of muscle basal lamina, such as laminin and fibronectin, which are known to play an important role in axonal outgrowth.

Abstract:

Liquid desiccant cooling can provide control of temperature and humidity, while at the same time lowering the electrical energy requirement for air conditioning. Since the largest energy requirement associated with desiccant cooling is low temperature heat for desiccant regeneration, the regeneration process greatly influences the overall system performance. Therefore, the effects of variables such as air and desiccant flow rates, air temperature and humidity, desiccant temperature and concentration, and the area available for heat and mass transfer on the regeneration process are of great int

Abstract:

According to the structure and working principle of rotary air preheater,the heat transfer calculation model is set up with reasonable simplification. Combining with the design parameters of the rotary air preheater of a 400 t/h pulverized coal boiler unit ,the results of practical calculation show that the said thermodynamic calculation method not only has higher precision of calculation,but also can get the temperature distributions of the gas, air and heat surface in each cross-section of the rotary air preheater. The result of numerical simulation calculation tallies well with the original

Abstract:

The inactivation kinetics of horseradish peroxidase (HRP) heated in capillary tubes in the range 110 to 135°C was studied. Its regeneration kinetics when stored at 4 and 25°C was also considered. As the severity of the treatment increased, the absolute value of the regeneration decreased. The storage temperature of the enzyme did not affect the percentage of maximum activity regenerable, although when this temperature was raised from 4 to 25°C the speed of regeneration increased. Kinetics of HRP inactivation determined after heating and after regeneration were compared. Both forms of the enzym

Abstract:

Single-stage regenerative organic Rankine cycle (SSRORC) is a system that is used for increasing the simple organic Rankine cycle (ORC) performance. Open feed organic heater (OFOH) addition in the ORC system increase power and efficiency of the system. This paper analyzes the SSRORC performance with a variation of P6/P1 ranges from 1.25 to 3.75 with an increment of 0.25, where P6 is the OFOH pressure at the inlet side and P1 is the pressure at the inlet pump 1, respectively. Hot water was used as the heat source with 100 °C and 100 l/min of temperature and volume flow rate as the initial data.

Abstract:

This study presents a solar desiccant system using an adsorbent in an “integrated desiccant/solar collector” that uses direct solar energy as a heat source for efficient regeneration of the adsorbent. The objective of this study is to investigate an integrated desiccant/collector in which the adsorbent absorbs solar radiation fully and is heated for regeneration. Another objective is to obtain the regeneration characteristics in the equipment proposed by both experiments and simulations. Throughout this study, silica gel is used as the adsorbent.
