The installation of suitable installation material in buildings is a cost effective way to reduce energy costs. The manufacture of insulation from minerals or mineral products, such as glass. Recycling glass to form insulation materials is another way to keep the process "green".
The manufacturing of glass wool begins with glass melting and refining. Here, molten glass is produced in a furnace running up to 1700°C. The molten glass is formed into fibres through the rotary spin processes, with a chemical binder is simultaneously sprayed on the fibres as they are created, which is a resin to hold the fibres together in the finished product. Typically the binder consists of a solution of phenol-formaldehyde resin, water, urea, lignin, silane, and ammonia.
Emissions from the glass wool process need to be measured at various locations. The furnace flue gas for melting the glass as a starter will require monitoring for combustion gases such as CO, NOx and SO2, if fossil fuels are used.
In the forming and curing of the glass wool, emissions of components of the binder that have vaporized need to be monitored – so Formaldehyde, Ammonia, Phenol and other phenolic species all need to be measured. Protea’s range of FTIR gas analysers are ideal for measuring these gases, as we can detect and speciation out these gases. The multiple range of our equipment means that the high concentrations in process can be monitored. As well as the post-abatement emissions to atmosphere for legislative reporting can be measured with the same analyser, if the site is using wet ESP, thermal oxidiser, scrubbers or other filtration means.
