By Pass Coal Analyzer

DF-5703(B) By-pass Neutron Activation Coal Analyzer

DF-5703(B) by-pass neutron activation coal analyzer needs to take coal samples from the sampling system, and then presents the detection results once every one minute. By analyzing main coal parameters and industrial indexes in a real-time manner, it can effectively supervise and control coal quality, and is characterized by short analysis time, high analysis precision, etc.

Principle:
DF-5703(B) adopts prompt gamma neutron activation analysis (PGNAA) technology. 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 got.

Technical parameters:
1.Measurement parameters: ash content, moisture, sulfur content, SiO2, Al2O3, Fe2O3, CaO, MgO, Na2O, K2O, etc.
2.Calculation parameter: calorific value and any possible parameters that can use empirical equation.

Product application:
1. Incoming coal detection
Application objects: Such major coal consumers as power plants, cement plants, iron and steel plants, coal chemical plants, etc.
By combining with a sampling system, that analyzer can measure incoming coals in a quick, accurate and objective manner and solve the above problems effectively. The analyzer is embedded in a sampling system to monitor incoming coal quality on real-time basis and at a fast speed. Fully automatic measurement and presentation of the measurement results by vehicle number ensures coal measurement accuracy and timeliness and provides scientific data for incoming coals.
