The 15 cooling fans of the front-line grille cooler are adapted according to the original design. As the output of the rotary kiln continues to increase, when the output of the rotary kiln reaches more than 5500t/d, the cooling capacity of the grate cooler is obviously insufficient. During production, the operation continued to adjust and optimize the material bed and clinker granulation. Even though 15 grate coolers were operating at full capacity and the valve opening was almost 100%, the clinker cooling requirements were still not met. The clinker temperature at the kiln outlet still reaches about 200°C, especially during summer production, the clinker temperature is higher according to the technical requirements of production design, the clinker temperature at the kiln outlet should be room temperature; plus 65°C, andthe reasonable clinker temperature should be 90°C ~ 100°C, the clinker is actually 100°C higher than expected, a large amount of heat is discharged by the clinker and is not recycled, causing waste; energy and increasing the coal consumption of the clinker.
For systems equipped with furnace head AQC furnace waste heat generation, the cooling efficiency of the grate cooler should be higher. Not only should the temperature of the secondary air and tertiary air be increased, but also. the AQC furnace exhaust gas temperature should also be equal. The air volume must be sufficient. Due to the poor cooling effect of the grate cooler, the cooling air cannot completely exchange heat with the clinker, and a large amount of heat is discharged with the clinker, which not only increases the coal consumption of the kiln rotary. OfAdditionally, the thermal enthalpy in the exhaust gas is reduced, and the waste thermal energy production is also reduced accordingly. The rated first-line residual thermal power generation capacity is 7,000 kW/h, and the average power generation is about 6,000 kW/h. It is difficult to operate above 6,500 kW/h. Electricity production per ton of clinker is only 23 to 24 kW. /t. It has been running at low load for a long time and has not reached the overall energy level, resulting in huge energy waste. Clinker cooling largely depends on the quenching effect, i.e. quenching of the high temperature recovery zone of the grate cooler. Inflatable beams and resistance grid plates are used in the high temperature recovery area to improve cooling air distribution. and improve clinker quenching.
What are some ways to save electricity?
Yes. Software and information technology services, information transmission, warehousing and postal services, rental, scientific research and technical services, finance, water conservation, environmental and public facilities management, services to residents, repairs and other services, education, health and respect for the environment.

Detailed informationThe service sector has gone through a long processabove history, from the service of life to the service of production. The social nature of the service sector has also changed with the development of history. In pre-capitalist societies, they primarily served slave owners and feudal lords. The capitalist service industry was about profit, and the relationship between capitalists and service workers was an employment relationship.
The socialist service industry is based on public ownership of the means of production and aims to improve the material and cultural life of the population. It’s an industry that truly serves society as a whole.

Save electricitySmall suggestions, for reference:
1. Save electricity and turn off the lights when people leave.
2. Do it yourself to save energy, protect theenvironment and save money.
3. Turning off the lights is a small step and a big step towards saving energy.
4. Reduce the sleep time of computer monitors, printers, copiers, and other electrical devices to achieve a “shutdown when people are away from the machine.”
5. Avoid peaks in power consumption. During peak periods, use high-wattage electrical appliances as little as possible.
6. Adhere to "turn off lights at will and eliminate waste" and achieve the goal of "turning off lights when people leave, stopping when people leave, and not turning on lights when there are enough light. Wait
