Fly ash can be added to clinker to make Portland cement composite, which can increase the initial strength.
It can also be added to asbestos tiles and floor tiles. Can increase intensity and adjust color.
It can be used to touch the wall during the greasy phase of the project.
Generally speaking, cement plants use it more.
What are the types of hazardous waste in coal-fired power plants?
Depending on the type of coal-fired boiler, some boilers (such as chain kilns, gas kilns coal jet), etc.) mainly produce pieces of ash, usually cooled with water and broken into small pieces. Some boilers (such as pulverized coal furnaces, circulating fluidized bed boilers, etc.) mainly produce fine coal ash. According to different processes, some are cenddry res (like electrostatic precipitator, bag duster, etc.) and others are wet ash. (like wet dusting). The emission, storage and transportation of dry ash can easily pollute the environment, but market demand is large and steps are being taken to gradually move toward dry ash.
The role of slag collection machines in thermal power plants
Coal-fired thermal energy production units must now be equipped with desulfurization and denitrification projects. Despite this, desulfurization and denitrification are necessary. still effective to a certain extent and cannot guarantee complete takeoff safety.
Wastewater contains heavy metals and there is a large amount of CL▔ in the desulfurization system
Exhaust gas contains nitrogen oxides, oxides carbon, sulfures, dust, etc. ;< /p>< p>Solid waste, ashes and dust can be sold to make cement, etc. The ashes cannot be used at all and most heavy metals remain in the ashes. The ashes are generally landfilled. Coal-fired power plants are equipped with ash dumps;
Waste heat, there are two types of cold ends of coal-fired power plants, one is the cooling tower, and the heat at the cold end is discharged to the atmosphere; the other Since rivers, lakes and seas serve as cold sources, the heat is released into the rivers, lakes, rivers and seas, causing serious ecological damage to the water intake areas of cooling and drainage.
Thermal power plant slag collection machine: It is the main equipment for mechanical slag removal in power plants thermic. The scraper slag shovel is placed at the bottom of the boiler, and the ash and slag are discharged from the end of the slag shovel for loading by conveyor or truck to achieve continuous and efficient slag discharge . Slag can also be transported directly by truck. achieve intermittent slag discharge. This machine can also be used to transport gravel, coal or other solid materials.
Operating principle
The equipment is installed under the kiln slag outlet. It consists of an upper and lower tank body, an overflow tank, a driving device, a transmission device and a guiding device. The slag passes through the slag pit and closes the door, then falls into the upper water tank of the slag shovel. The ashes and slag are cooled, cracked and depositedu bottom of the tank. They rise gradually with movement. of the transport scraper, discharging most of the cooling water and collecting the slag. They are discharged from the end of the machine for belt transport, hydraulic transport or loading and unloading.
