Case details

The fly ash produced in the coal burning process needs to be centrally stored in the ash storage bin or ash reservoir, and then sent to the open pit mine. In order to measure the level, it is necessary to use a radar level meter and a high alarm instrument.

Case details

The stacked gypsum is pushed through a scraper reclaimer to a belt conveyor and then transferred to a waiting transport vehicle. The radar level meter measures the level height of the gypsum pile, thereby controlling the position of the reclaimer and enabling efficient transport arrangements.

Case details

A spray head is arranged in the circular cooling tower to spray out the hot water that needs to be cooled. After the hot water enters the cooling tower, the air absorbs heat, expands and rises, thereby driving the flow of fresh cold air below (chimney effect). Through the dehydrator in the tower, the cooled water drips again into the sump. Therefore, the water level of the sump must be measured continuously.

Case details

In coal-fired power plants, lignite and hard coal are temporarily stored in 15 m high bunkers. In order to ensure that the coal conveyor can run uninterrupted, it is necessary to measure the coal level height safely and reliably. In addition, limit alarm device can be installed to avoid coal bunker overflow.

Case details

In coal-fired power plants, the coal used for boiler combustion needs to be taken out of the bunker through the chain conveyor, and then sent to the mill through the coal feeder, where it is ground into pulverized coal and then blown to the boiler. In order to ensure the stability of the coal supply of the boiler at full load and especially at low load, three instruments need to be installed on the conveyor belt for redundant measurements.

Case details

The desulfurized gypsum obtained from the flue gas desulfurization equipment is delivered to the gypsum warehouse by a conveyor belt (belt stacker). In order to ensure safety, it is necessary to use two radar level meters at the end of the conveyor belt to monitor the pile height. When the pile height reaches the specified position, the stacker moves forward.

Case details

Steam turbine is a very complex equipment, among which the turbine oil that plays a lubricating role is very important. Turbine oil ensures the smooth operation of equipment, significantly reduces maintenance costs and avoids turbine failures. The main component of steam turbine oil is high quality mineral oil, which has the characteristics of anti-emulsification (water separation) and air release. The oil level in the tank must be monitored to ensure that there is always enough turbine oil for lubrication.

Case details

In the absorption tower, the sulfur in the flue gas is absorbed by spraying limestone slurry. In order to ensure that there is enough limestone slurry for the absorber, a separate slurry preparation tank is required. Gauges are used to regulate the tank level to reliably avoid tank overflow.

Case details

In order to achieve efficient combustion of boilers, coal-fired power plants need to use fuel oil first, and then invest in the original fuel, which is coal. Fuel is stored in large tanks that require level gauges.
