Abstract
锛?/p>
The dehydrated residual sludge with a water content of 85
锛?/p>
from the treatment
of chemical wastewater was mixed into fuel coal in different proportions
锛?/p>
Then
锛?/p>
an analog co
mbustion of the mixture was performed in a CRF semi-industrial thermal combustion test rig t
o test working safety of the heated surface of the boiler
锛?/p>
the stability and efficiency of t
he combustion and the changes of off gas discharging and of dregs composition. When the mixi
ng ratio of sludge was below 6 percent
锛?/p>
the combustion did not produce harmful effect to the
working safety of the heated surface of the pulverized coal boiler
锛?/p>
and when the mixing rati
o was
鈮?/p>
2 percent
锛?/p>
the off gas discharging could meet the environmental protection requirem
ents
锛?/p>
the optimum mixing ratio being 2 percent
锛?/p>
