Additives for Steam Boiler Systems
The fundament for the assessment of boiler water in Austria is the so called „Dampfkesselbetriebsgesetz“ (Law for Operating Steam Boilers, BGBl. No. 212/1992 i.d.g.F.) and the ABV (BGBl. No. 352/1992 i.d.g.F.), which has been passed subsequently to BGBl. No. 212/1992.
An essential part of the corrosion prevention in steam boiler systems is the fight against oxygen: Oxygen in feed water, which can lead to very heavy corrosion in the boiler, is firstly removed largely by thermal degassing; afterwards still existing oxygen has to be fixed with specialised oxygen scavengers like sulfite, DEHA or hydrazine.
For this special corrosion protection purpose in steam boiler systems we are able to offer five basic product types:
Combination products with O2 protection based on sulfite
These products are delivered as combined protection agents, so that by addition of one single product an optimum of corrosion protection is achieved, However sulfite is not steam volatile, hence steam and condensate sections of the system are not protected by these products; on the other hand an unlimited application in the food industry is possible.
