Respectively take 10g as sample compound A-B at random, use micro- sem observation, it is observed that：It is larger in compound B
Particle (may be considered fusion formed particle) concentrate on center substantially, do not scatter；And it is larger in compound A samples
Particle (may be considered fusion formed particle) be distributed in everywhere, disperse more uniform.Therefore, addition Boratex has
Help make poly butylene succinate equably merge with other raw materials, be then observed that the bulky grain being fused into throughout
It is uniformly distributed.
2nd, calcining matter chemical change
The Nexus 670 of Nicolet companies of the U.S. is used to embodiment 2, the compound A-B of comparative example 2 and calcining matter A-B
Type Fourier transformation infrared spectrometer is detected under similarity condition.As a result find：Compound B and calcining matter B infrared light
Spectrum is extremely approximate；Calcining matter A and compound A infrared spectrum difference is larger, except the ester group absworption peak in calcining matter A spectrograms subtracts
It is weak outer, 3 absworption peaks more than the spectrogram of calcining matter A infrared spectrum also than compound A.Therefore, addition Boratex helps to gather
Chemical change occurs in roasting process for succinic acid-butanediol ester.
Experimental example 3：Desulfuration efficiency
Determine dioxy in gas 1-2, gas A-B cumulative volume and each gas that embodiment 4-5 and comparative example 3-4 is collected into
Change the content of sulphur, and calculate desulfuration efficiency according to the following formula, the results are shown in Table 2.
Desulfuration efficiency=100% × (V0×C0-V×C)/(V0×C0×t)
Wherein:
The cumulative volume (L) for the gas that V obtains for collection；
Content of sulfur dioxide (mg/L) in the gas that C obtains for collection；
V0For the cumulative volume (L) of flue gas；
C0For sulfur dioxide in flue gas content (mg/L)；
T is desulfurization time (h).
Table 2
As shown in Table 2, compared with comparative example 3, the desulfuration efficiency of the utility model device is higher, more economy.Also,
Compared with comparative example 4, when the utility model carries out desulfurization to flue gas at high temperature using the mixture of nitrogen and desulfurizing agent, desulfurization
It is more efficient.
Experimental example 4：Contamination and dust stratification amount
After coal combustion, the exhanst gas outlet flue (radial dimension and length phase of flue of observation embodiment 4-5 and comparative example 5
Contamination together) and dust stratification amount, the results are shown in Table 3.
Table 3
As shown in Table 3, relative to comparative example 5, the utility model device addition waterglass and calcium oxide together burn with coal
Contamination degree it is lower, dust stratification amount is less.
Obviously, above-described embodiment is only intended to clearly illustrate example, and the not restriction to embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or
Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or
Among the protection domain that variation is created still in the utility model.
