GCM Water understands the importance of continuous boiler monitoring. We take care of the water analysis function and leave the customer to concentrate on their core business.
GCM Water’s boiler analysis is dependent on the specific method of chemical treatment used varies with the type of boiler and the specific properties of the feedwater. So the boiler analysis will vary from operation to operation but GCM Water has the testing capability to cover all your requirements.
Proper boiler chemical control requires the testing of three types of water to ensure the water system is managed comprehensively.
Feedwater
Boiler feedwater is supplied from varying sources such as municipalities, dams, rivers or boreholes. All feedwater should be analysed in order to correctly determine chemical type needed as well as the dose rates of treatment the chemicals.
Depending on operation to operation, feedwater is usually a mixture of condensate and make up water from a pre-treatment system such as a softener, reverse osmosis, or demin plant. Typical tests used for boiler feedwater include:
- Chloride or salinity
- Conductivity
- Water hardness
- pH
- Silica
- Iron
- Suspended solids
- Dissolved Oxygen
- Total Dissolved Solids (TDS)
The frequency of the testing of the feedwater will be determined by the consistency of the water quality.
Boiler Water
The boiler is dosed with chemicals to maintain efficiency by preventing deposit formation and corrosion. The purpose of boiler water analysis is to keep the parameters within established limits.
Analyses of boiler water includes:
- Chloride
- Hydroxide (OH) Alkalinity
- pH
- Phosphate/polymer
- Silica
- Sulphite/hydrazine
- Total Dissolved Solids
Condensate
Condensate water is water that is system generated and will be sent back as feedwater. It is therefore critical to monitor it and ensure any contamination is picked up quickly and remedial action taken.
Analyses of steam should include:
- Ammonia
- Conductivity
- Copper
- Iron
- pH
- Conductivity/TDS
