How can kiln manufacturers reduce the heat extraction of roasting kiln cooling zone
In the case of ensuring the drying effect of the drying kiln or at least ensuring that the drying kiln does not collapse the billet, the heat extraction of the roasting Baoling can be appropriately reduced.
According to the heat balance calculation of the furnace of the kiln manufacturer, the heat required for manual drying accounts for about 30% of the total heat in the kiln. If measures can be taken to reduce this ratio to about 20%, it can save a lot
Lireli can reduce the underfire of finished bricks accordingly. The measures that can be taken are as follows:
a. Make full use of the billet storage line, so that the well-coded brick billets can be fully dehydrated on the billet storage line using the ambient temperature. When the moisture content of the bricks entering the drying kiln decreases by 1%, the drying treasure can be reduced accordingly
Heat consumption 6% ~ 8%:
b. The principle of drying in low temperature and strong wind can be used. When the supply air temperature is slightly lower, measures to increase the wind can be adopted to achieve a better drying effect. Intake air in heat exchange fan
More cold air at the mouth can achieve this purpose:
e. It is also a good energy-saving measure to send part of the high-temperature flue gas of the exhaust fan into the drying treasure:
d. The low-temperature hot air extracted from the bottom of the kiln is generally 60C ~ 80C). Using the hot air blower to feed the drying treasure, it can also save part of the heat of the roasting kiln:
e. When the above measures are taken, the above two measures c and d are actually energy-saving measures taken during the design of the kiln. If this measure is not taken during the design, it will be difficult to implement during on-site operation)
When the dry residual moisture content exceeds the standard, we generally require the average residual moisture content of the dried bricks to be less than 2%, the smaller the better), can be used in conjunction with a tropical brake to ensure the calcined quality, although and measures d
It is a bit contradictory, but the use of bridge brakes is a relatively compromise method, which can not only ensure the firing quality of bricks with high residual moisture content, but also not waste the Dali heat.
