CAHENG---Low Temperature Waste Heat Power Generation Technology in Cement Plant
Large kiln furnace generally uselarge-scale kiln door cover technology and the third generation of inflatable grate cooler. Both of these have played a crucial role in recovering heat and reducing kiln exhaust gas temperatures. Large kiln door cover technology on the decomposition furnace with three wind kiln door cover, so that the wind speed tripled greatly increased, and now the wind speed three degrees basically rose to 900 ℃ above, three temperature rise, the corresponding reduction. To improve the wind temperature three times, but also from the operation to ensure that the ventilation in the kiln case, should be used as much as possible three times the wind, so that the rapid decomposition of coal pulverized coal to reduce the possibility of whirlwind coal combustion. Reducethe preheater outlet temperature. The third generation of inflatable grate cooler is the distribution of the air volume on the grate plate is more uniform, you can take the thick layer of operation to reduce the short-circuit phenomenon of the wind, clinker can play a role in quenching, but also to maximize the realization of high temperature zone Restore heat
Our company's cement plant low-temperature waste heat power generation technology has made great progress, and now we have to protect the new plant has completely canceled the power generation boiler fuel, complete use of kiln system emissions to tons of clinker actual power generation 35kWh, 320 years of operation Calculation, 5000t clinker production line can generate 5600kWh each year, the annual savings of 2240t standard coal, the energy saving effect is quite obvious
