The results indicate thatthe efficien- cies of heat exchange and heatrecovery after adopting cyclone separater are in the ranges of 65% to 75% and1 5% to2 0 % ,respectively. The above result reveals that the heat recovery rate from the CHRS is notvery high.
drawing μ--η,t ws --η graph and comparing the heat recovery rate under the spray coefficences and the reasonable out-door wet-bulb temperature to determine the heat recovery rate on the superior states.
Introducing a newly heat recovery unit-double spray chamber, utilizing the Fantran-77 computer language to acquire respective spray chamber s exiting paramers in term of equations, and with which acquiring the heat recovery rate matching with the spray coefficence.
Through utuhe revamping of heat exchange system, it is possible to increase the heat recovery efficiency from 67% to 80. 8% and the thermodynamic efficiency of heat exchange pro- cess from 65. 2% to 75. 8%.
Methods and main equipment of waste heat recovery in sulphur buring sulphuric acid plants are described Some measures of improving heat recovery efficiency are provided to decrease energy requirements, consumption and operation cost and increase economic benefits 〔
The temperature efficiency and heat recovery efficiency of honeycomb potter heat storage bed used in High Temperature Air Combustion are experimentally tested.
It was pointed out that the use of the double (multiple) shell heat exchangers can lower the capital investment, raise the thermal energy recovery ratio and the energy integration level of the process systems.
IA in serum bound with 125 I-insulin and the concentrations ofIRI and F-IRI were measured by radioimmunoassay (RIA). Results The hot recoveryratios of F-IRI assay in IA-negative and IA-positive serum were different(98.35% vs. 5.87%),but in cold recovery test no difference was found between the two groups(P>0.05).
The on-site tests show the plate heat exchangers give very good economical effects of waste heat recovery and the heat recovery ratio can reach to 80-90%.
A energy-analysis and exergy-analysis model is established for metal hydride cooling systems, in which the efficiency of sensible-heat recovery and hysteresis are considered. The working cycle of a metal hydride systems using LaNi5/MmNi4.15Fe0.85 as working media is simulated and its performances are calculated. The effects of plateau slope and hysteresis, heat recovery on system's performances are investigated.
The energy-analysis and its model are established for a metal-hydride heat transformer using LaNi4.5Al0.5/ LaNi5 as working media, in which the relative mass and specific heat capacity of reactors and the efficiency of sensible-heatrecovery etc. are considered. The effects of heat source temperature, the relative mass and specific heat capacity of reactors, the efficiency of sensible-heat recovery and the ratio of hydrogen transfer on system's performance are investigated.
