Carryover also known as priming is any solid, liquid or vaporous contaminant that leaves a boiler with the steam. In low/medium pressure boilers (<100 bar) entrained boiler water is the most common cause of steam contamination.
L8 is the Health and Safety Executive document that gives recommendations for the control of Legionnaire’s Disease. It recommends that domestic water tanks are inspected annually and if found to be dirty should be cleaned and then disinfected.
This is caused by the unchecked growth of micro-organisms which form a slimy biomass. The effect of the biomass is to restrict water flow, reduce system capacity, and inhibit heat transfer much the same as with deposition. The types of organisms most often encountered in industrial water systems are: Bacteria Algae Fungi Protozoa Some organisms…
The objective of a boiler water programme is to control/minimise deposit formation, corrosion and carryover, in order to achieve this, a treatment programme will comprise: An oxygen scavenger Polymers to provide deposit control Phosphate except for steam generators or where feedwater quality is very high and the Feedwater alkalinity is a high proportion of TDS…

Where the removal of chlorine is needed from the water (for example if there…
Broad Spectrum Biocides offer an encompassing solution to microbiological control Biocides can be useful for the control of microbiological organisms which can become very attached to the environment of your water systems be they cooled or chilled or even low temperature closed systems. This can be bad news as some bacteria such as Legionella can…
From the heavily used chartered steam train to the traction engine that only see’ service at a number of heritage fairs a year, all types of steam locomotive should receive water treatment of some kind. For many this is Tannin and Soda ash and maybe even a polymer sludge conditioner.
Corrosion inhibitors for Closed, heating and cooling water systems Corrosion inhibitors are an essential to ensure the longevity and efficient operation of your closed heating or cooling water system. The two main types of treatment for closed systems are nitrate or molybdate based corrosion inhibitors. In certain circumstances using a Tannin based inhibitor may be a better choice if,…
