plics® − easy is better Instrument platform plics® The plics® idea is simple: Each instrument is assembled from prefabricated components once the order is received. This modular design allows full flexibility when selecting the required sensor features. You receive your customised, user-friendly instrument within an amazingly short time. The best part: these instruments are more cost-effective and advantageous in every way – throughout their entire life cycle. Display and adjustment The display and adjustment module PLICSCOM is used for m ­ easured value indication, adjustment and diagnosis...

Depandable measurement Level measurement and point level detection in the coal surge bin even during filling In a typical coal power plant, lignite (soft coal) and anthracite (hard coal) Cost effective are stored temporarily in bins up to 30 meters high. To ensure that the coal Efficient use of the entire container ­capacity User friendly belts are continuously loaded without interruption, a robust and reliable level m ­ easuring system is required. Additional point level detectors are used to prevent any overfilling of the bins. Simple mounting and setup VEGAPULS 69 Non-contact level...

Feed belt to the coal mill Reliable Quantity measurement on the feed belt to the coal mill Reliable monitoring of chain To fuel the power plant boilers, chain conveyors must first bring raw coal from conveyor loading Cost effective Optimal plant operation User friendly the bunkers. Feed belts (distributors) then transport the coal to the coal mill, where it is ground into dust and blown into the boiler. In order to ensure the fuel supply to the boiler in periods of full load, and especially low load, three redundant measuring systems are employed per feed belt. Simple installation without...

Combustion air pipe Reliable Combustion air flow measurement Reliable flow measurement To ensure an optimum combustion process in a coal-fired power plant, the of ­ ombustion air c Cost effective Exact volume control possible for optimal combustion process User friendly amount of air flowing in the pipes leading to the furnace must be ­ arefully c monitored. A Venturi section of the air pipe is a defined constriction in which the pressure drops a few millibars proportional to flow rate. Differential p ­ ressure transmitter measures the pressure drop across the measuring section very...

Level measurement in the wet deslagger Reliable water level measurement In a coal fired power station, either hard coal or brown coal is burned as ensures optimal operation of the ­process Cost effective Maintenance-free measurement with high accuracy User friendly the main energy source. Most plants have a so-called “wet deslagger” for e r­ moving the bottom ash (slag) from the combustion chamber. Level control in the wet deslagger fulfils two important functions: First and foremost, it controls the water level, which cools and removes the hot slag. Secondly, it maintains a hermetic seal...

Lime milk pipeline Reliable Density measurement in lime milk Maximum safety through approvals In today’s power plants, the wet process with lime washing has established a ­ ccording to SIL Cost effective Reliable density measurement itself as the primary method for flue gas desulfurization. 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. ensures high plant availability The sulphur dioxide is converted into calcium sulphite, which then falls into User friendly...

Wet gypsum storage hall Reliable Level measurement in the wet gypsum storage hall Reliable function under The gypsum extracted from the exhaust gases in the flue gas ­ esulphurisation d all operating conditions Cost effective Simple installation on existing unit is stored in the wet gypsum storage hall ready for further transport. Level sensors are needed to determine the stockpile height of the gypsum and quantity of the stock to optimise transportation management. ­infrastructure User friendly Maintenance-free operation VEGAPULS 69 Non-contact level measurement with radar in the wet...
