Thermal circuits can become complex based on the operating pressures, the type of makeup water, the use for which the steam is intended, the characteristics of the users, the length of the distribution lines, the quantity of recovered condensate etc.
To function properly, thermal circuits require a systematic and complete approach: prepare the feed water before it enters the boiler, protect and keep the surfaces of the boilers clean, constantly monitor the significant process parameters and maximise the condensate returns.
We have studied a line of chemicals exclusively designed for the treatment of boiler water and steam-condensate networks, capable of:
- Avoiding the formation of deposits in all water circuits;
- Minimising corrosion in the boiler, in the steam distribution system and in the condensate return system;
- Minimising foams and water entrainments into the steam, hereby ensuring the best steam quality.
A single day of lost steam production can, in fact, lead to higher costs than the cost of a proper water treatment program.
Scientific studies have shown that every mm of calcareous encrustation on the heat exchange surfaces increases the need for energy input by up to 9%, to satisfy the same heat demand.*
This problem also poses a serious safety risk. As high temperatures and pressures are reached in steam generators, if deposits hinder the heat exchange between the flame (and the fumes) and water, the pipes overheat, hereby leading to the risk of explosion.
Through the appropriate precautions we are able to guarantee:
- A long plant life to avoid costly downtime and unplanned capital expenditure;
- Maximum efficiency and excellent thermal efficiency;
- Safe and reliable steam production that avoids production interruptions;
- Saving of water and energy that immediately reduces total operating costs by 8-15%;
- Safe and risk-free operation;
- Minimal maintenance.
