Online Chemical Elemental Analyzer on Conveyor Belt
Product Description
Online Chemical Elemental Analyzer on Conveyor Belt
Single Channel Analyzer on-belt ash-in-coal data for real-time control of plant operations. Recent advances in technology pioneered have significantly improved the performance of dual energy Ash Analyser.
Ash consists mainly of oxides of metallic elements like Si, Fe, Al and Ca. Multi-Channel Element Analyzer Measures the combined total of these elements present in the coal, and this correlates directly to the total Ash.
Two radioactive sources are used:
Am-241: low energy gamma radiation. Absorption of Am-241 gamma rays selectively occurs due to the presence of the major ash-forming elements (Si, Fe, Al, Ca) and the bed depth of the coal.
Cs-137 : high energy gamma radiation. Absorption of Cs-137 gamma rays will be due only to the bed depth of the coal. This allows the Am-241 measurement to be normalised for bed depth. The normalised Am-241 absorption is then correlated to total Ash Analyzer For Cement content by calibrating against laboratory reported ash sample results.

Successful Case: a power plant in India
An Indian company initially purchased 12 sets of EA-COAL through a single contract in 2017. All these analyzers are used for coal quality testing of burning coal. Online detection of coal quality data can be used to guide coal blending process. In the control room, the operator can adjust the coal blending ratio of different grades of coal through the coal quality information displayed by the instrument, in order to ensure the quality stability & optimize boiler feeding. It helps to reduce the cost of coal burning, excels the automation level of the power plant and eventually helps to improve boiler performance and also minimizes its maintenance. In view of the good effect, the company has placed order for six sets more EA-COAL successively.

Application
1. Classified Stacking
EA-COAL system can be used in combination with the process Integrated Control System to classify and stack the raw coal & incoming coal to plant. For the coal washing plant, the coal with high calorific value can be sorted out to maximize the output of high-quality coal; for the power plant and coal chemical industry, the coal can be classified and stacked according to the quality, which is conducive to the subsequent stable coal blending.
2. Coal Blending
EA-COAL system can be used in combination with the automatic proportioning system to optimize the process control of coal blending. The weighing scale and analyzer keeps on sending current analyzed results to the batching system on continuous basis. According to the target value of the user's quality control parameters (calorific value, sulfur content, ash content, and volatile matter, etc.), the batching system will give the optimized formula, and control the amount of feed for each raw material feeder in real-time to make the batching meet the quality control requirements. The batching system can also use manual mode to dispatch the feed quantity of each coal source through intercom system or other ways to guide coal blending.
