Coal Power Plant
Absorber
Energy
The lime milk sprayed into the flue gas desulphurization system collects at the bottom of the absorber. The level has to be monitored to ensure that the absorber pumps do not run dry.
Absorber pump
Energy
Before the flue gas enters the absorber (scrubbing tower), its pollutant content (sulphur) is measured. If the degree of pollution of the flue gas requires it, the absorber pumps are switched on and a...
Adipic acid mixing tank
Energy
Adding adipic acid to the lime milk increases the effectiveness of the desulfurization process in the absorber. This is done by mixing adipic powder with water in the mixing tank. This acid lowers ope...
Ammonia feed tank
Energy
To protect the environment, the nitrogen oxide content in the flue gas is reduced as much as possible. This is accomplished by adding air and ammonia to the flue gas. Through a chemical reaction, the...
Belt transfer station
Energy
In a coal power plant, either hard coal or brown coal is burned as the main fuel source. The coal is transported on conveyor belts to the furnace. To avoid backup or overfilling at the belt transfer s...
Coal stockpile
Energy
After being unloaded from rail cars or ships, the coal is stored in stockpiles. Here, reliable measuring systems that function properly in any kind of weather are essential for level monitoring and be...
Coal surge bin I
Energy
In a typical coal power plant, lignite (soft coal) and anthracite (hard coal) are stored temporarily in bins up to 15 meters high. To ensure that the coal belts are continuously loaded without interru...
Coal surge bin II
Energy
In a typical coal power plant, lignite (soft coal) and anthracite (hard coal) are stored temporarily in bins up to 30 meters high. To ensure that the coal belts are continuously loaded without interr...
Combustion air pipe
Energy
To ensure an optimum combustion process in a coal-fired power plant, the amount of air flowing in the pipes leading to the furnace must be carefully monitored. A Venturi section of the air pipe is a d...
Conveyor belts for coal
Energy
For optimal quantity measurement of the coal being conveyed to the power plant or to the individual boilers, a continuous flow of material must be ensured. Throughput measurement on the conveyor belts...
Cooling tower basin
Energy
At the bottom of the cooling tower there are nozzles for atomizing and cooling incoming hot water. As the heated water is sprayed up inside the cooling tower, it warms the air, which expands, flows up...
Cooling water intake
Energy
Coal fired power stations use huge amounts of cooling water. This water is usually taken from rivers, with the help of specially built intake structures. At these extraction points, reliable level mea...
Cooling water pumps
Energy
A considerable amount of cooling water is required for a coal power plant. Large, powerful pumps are needed to keep the huge quantities of water circulating. Robust and adjustment-free sensors ensure...
Feed belt to the coal mill
Energy
To fuel the power plant boilers, chain conveyors must first bring raw coal from the bunkers. Feed belts (distributors) then transport the coal to the coal mill, where it is ground into dust and blown...
Fly ash silo, ash bunker
Energy
The burning of coal creates huge quantities of ash. It is collected in a silo or bunker and then dumped into an open pit. To determine the filling height, radar transmitters and level detectors are de...
Fuel oil storage tanks
Energy
To start up the combustion process in a coal power plant, fuel oil is required. Then later the plant switches over to its proper fuel, coal. The fuel oil is stored in large storage tanks equipped with...
Heating condenser
Energy
In the heating condenser, steam is used to provide energy for a district heating network. The outgoing temperature of the heating water is controlled by the prevailing weather conditions. As part of t...
Level measurement in the raw water basin
Energy
The raw water facility, is extracted mostly from rivers, it is conditioned for use in the steam and condensate loops. Reliable level measurement in the raw water basin ensures that there is always an...
Lime milk pipeline
Energy
The flue gas enters the scrubbing tower (absorber) and cools down further. Here the lime milk (gypsum suspension) is sprayed into the flue gas to wash out the SO2 gas component. The sulphur dioxide is...
Lime milk storage tank
Energy
The sulphur in the flue gas is chemically bound by injecting lime milk into the scrubbing tower. To ensure that there is always enough lime milk available for the scrubbing tower, sensors are required...
Lime silo I
Energy
Flue gas desulphurisation needs a continuous supply of lime milk, so the lime silos have to stay stocked. Lime clings to whatever it touches and the silo runs heavily dusty, which fouls instruments mo...
Lime silo II
Energy
Flue gas desulphurisation needs a continuous supply of lime milk, so the lime silos have to stay stocked. Lime clings to whatever it touches and condensation forms inside the silo, so one reading alon...
Oil feed tank
Energy
Turbines are highly complex systems in which lubricating oil plays an important role. The oil is used to ensure proper operation, to reduce maintenance costs to a minimum and to prevent turbine failur...
Receiving tank for feed water
Energy
The process water, which is usually extracted from a river, cannot be fed directly into the turbine loop until it has been treated. It has to undergo cleansing through filtering systems and ionizers....
Reversing conveyor
Energy
The gypsum extracted from the exhaust gases in the flue gas desulphurisation unit is transported by conveyor belts to the wet gypsum storage hall. The stockpile loading is carried out by a reversing c...
Silo for filter dust
Energy
In power plants, the flue gases are cleaned in several ways. One of them is electrostatic filtering, which efficiently extracts large amounts of dust from the gases. This material is collected in a si...
Steam drum
Energy
Process heat in a power plant is provided by steam at different pressures. The required process temperature is regulated via the steam pressure. Depending on the process temperatures there can be pres...
Steam pipe
Energy
To warm up the water for the boiler, steam is bled from the power plant turbine and delivered into a preheater. As the steam cools and condenses, it is removed from the preheater with pumps. Any conde...
Storage tanks for acids
Energy
The raw water, which is usually extracted from a river, cannot be fed untreated directly into the turbine circuit of the plant. It has to be treated first. To neutralize the water, either sodium hydro...
Storage tanks for fire water
Energy
To ensure fire safety, power plants are required to have an adequate supply of extinguishing water on hand for the fire brigade. The water is usually provided through a central fire water main. To mak...
Turbine steam line
Energy
The pressure in the steam loop has to be monitored at various points in the process. Reliable measurement is required especially at the inlets of the various pressure stages of the turbine. Pressure t...
Wastewater basin
