Waste heat recovery test result
Implement above-described embodiment 1-5 and comparative example 1-10 respectively, and carrying out the temperature variations before and after heat exchange with armoured thermocouple mensuration fresh air and damp and hot waste gas respectively, then the waste heat recovery rate of damp and hot waste gas is calculated, each embodiment and comparative example repeat five times, get its mean value to calculate, acquired results is as shown in table 1 below.
The waste heat recovery result of table 1 embodiment 1-5 and comparative example 1-10
As seen from the above table, when the temperature difference of step 2 is 9 DEG C, waste heat recovery rate is the highest, be 99.1% (embodiment 1), and when changing the temperature difference in step 2 a little (embodiment 2-5), all the reduction of waste heat recovery rate will be caused, but the rate of recovery now is still greater than 93%, but when temperature difference is not 1 ~ 10 DEG C of this scope (comparative example 1-5), the rate of recovery significantly drops to about 80%, the rate of recovery unexpectedly reduces about 15%, proves that temperature difference has remarkable impact to waste heat recovery thus.
Also can be found out by comparative example 6-10 simultaneously, be less than 80%RH when damp and hot waste gas humidity or be greater than 95%RH, waste heat recovery rate is all at about 82 (see comparative example 6-10), and the waste heat recovery rate of embodiment 1-5 is between 93.8-99.1, this further demonstrates damp and hot waste gas humidity and waste heat recovery is also even more important.
Therefore, apply to said method to control above-mentioned low temperature latent heat when releasing little temperature difference waste-heat recoverer, the heat exchange fully in time of damp and hot waste gas and fresh air can be realized, thus reach structural safety, the best combination that easy for installation and heat energy recovery rate is high.
Above specific embodiments of the invention are described.It is to be appreciated that the present invention is not limited to above-mentioned particular implementation, those skilled in the art can make various distortion or amendment within the scope of the claims, and this does not affect flesh and blood of the present invention.
