Model PAF 2014 Dual Furnace Coal Ash Fusion System

Z90-8252-02Model PAF 2014 Dual Furnace Ash Fusion System, 230Vac / 1ph / 50-60Hz



The Preiser Scientific Ash Fusion System is designed to determine ash cone deformation temperatures in coal and coke ash per ASTM Standard D-1857 and ISO Standard 540 (CO/CO2 reducing atmosphere option).

The Model PAF 2014 Dual is comprised of two furnaces, control tower, and a user interface PC.  An all-in-one style PC running Windows® operating system accommodates both image collection and analysis concurrently.

The mechanical structure features a functional design offering a "user friendly" operation coupled with very low maintenance.  The swing away camera mounting allows for easy image alignment and unobstructed sample insertion on both the single and dual furnace models.  

The control tower consists of the furnace temperature controller, over temperature protection, and video capture.  Video and furnace communications to the user PC are via a single USB interface transferring furnace command and query requests along with live streaming video from furnace cameras.

The analysis software allows the user to manually review and generate reports of completed tests.  An autosuggest algorithm is available to pre-populate analysis for the laboratory technicians’ review and refinement.  Test results, log files, and instrument settings can be viewed within the program.  These files can be directed to a printer, forwarded with built in email, viewed on a shared drive, or accessed via a LIMS system.  Instrument data storage allows the accumulation of approximately of 5 years of test data and images.  It is suggested that data archiving be scheduled on a 6-12 month basis for heavy instrument usage, and longer intervals for lighter use.  

An in-program Help Manual provides operational information and reference.  Remote on-line assistance and training can be provided.
