Anhydrous Ammonia Burning
by Jeremy Williams on May.18, 2020, under News
Did you know that ammonia can burn? Pure anhydrous ammonia’s fuel rangeis accepted to be 15%-28% ammonia and remaining being air. This is 150,000 PPM – 288,000 PPM, way above life sustaining concentrations. Not all vendors/suppliers can agree to the flammability of the chemical. See below from these vendors recent SDS sheets.
We are excited to release today’s R-171 Video Tip of day “Can Ammonia Burn” presented by Jeremy Williams of GCAP.
Ammonia Refrigeration Systems and Anhydrator Vessels
by Jeremy Williams on May.12, 2020, under News
Anhydrous means lack of water, unfortunately ammonia is hydroscopic which means it loves water. Water can get in an ammonia system approximately six different ways and should be removed for several reasons. If more information on how it comes in and how to remove please see this post.
An anhydrator vessel is simply a batch process subcooler. If systems are pipe accordingly, they can also act as an oil still and/or a pump out accumulator. We hope you enjoy today’s R-717 Video Tip of the Day presented by Jeremy Williams and brought to you by Garden City Ammonia Program
