How Does an Ammonia Refrigeration System Work? …

Ammonia refrigeration systems operate in a similar manner to fluorocarbon systems, but have several key differences. While you will not usually find an ammonia-based system inside a home (ammonia is a very toxic substance, and the refrigerators are very expensive), they are used in factories that need large refrigeration devices that can cool substances very quickly.

Science and technology of ammonia combustion - …

The advantages of ammonia are not only that it is a hydrogen carrier, but also its availability, amenability to storage and transport, and its utility as a fuel for various energy and industrial applications. The combustion of ammonia, which is the most effective way to use ammonia as an energy source, is …

Oxygen Scavenger for Feed Water & Boiler System

Accepta 2061 is a DEHA based oxygen scavenger; it is volatile and alkaline, contributing no dissolved solids or ammonia to the system, and can be fed into feedwaters used for spray at temperation. Accepta 2061 is not suitable for use with highly oxygenated feed waters – a minimum feed temperature of 85 o C is essential and de-aeration is
