Description

Online Coal Analyzer DF-5703(A) Online Neutron Activation Coal Analyzer DF-5703(A) adopts prompt gamma neutron activation analysis (PGNAA) technology to measure & compute various parameters in coal.The neutron source emits rapid neutrons with average energy at 2.35Mev, which are then degraded into thermal neutrons by the measuring unit. The thermal neutrons radiate materials, so that the thermal neutron capture reaction can be made among the nucleuses of various elements in the material to emit characteristic gamma rays with different energies and intensities.
  By testing the energy in characteristic gamma ray, the element categories in the material can be distinguished, and by testing the intensity of gamma ray with specific energy, the content of element can be determined.Measured parameters: ash content, moisture, sulfur content, SiO2, Al2O3, Fe2O3, CaO, MgO, Na2O, K2O, etc.
Calculated parameter: calorific value and any possible parameters that can use empirical equation.Application: Coal Classification & Piling, Coal Blending etc.Classification & Piling
DF-5703 (A) system can be used jointly with the process control system, so as to classify and pile the raw coal and commercial coal after washing in time. For coal washeries, it can sort the coals with higher calorific capacity to the maximum and improve quality coal output; for power plants and coal chemical plants, it can classify and pile the coals by quality, so as to facilitate subsequent stable coal blendingCoal blending
DF-5703(A) can be used jointly with the automatic batching software to carry out the optimized control during the coal blending course. Weighing instrument and analyzer can send current detection results into the batching software, and the latter then presents the optimization formula to control the feeding amount of each raw material feeder according to the target values of quality control parameters (calorific value, sulfur content and ash content) as set up by the users, so as to make the batching satisfy the quality control requirements. The batching software can also adopt manual mode. The feeding amount of each coal source can be controlled through the intercommunication system, thus guiding coal blending.
