Controlling boiler blowdown in industrial steam generators is an important process used to manage the build-up of suspended solids and so control the formation of scale, corrosion, and wet steam carryover. In this guide the experts at Water Treatment Services consider the operation of steam generators looking specifically at blowdown, what it is, how it can be used to improve operational performance and energy efficiency, and factors that need to be considered to optimise blowdown rates.
Managing boiler carryover in steam generating systems is an essential engineering process required to maintain steam purity and boiler system performance. In this expert guide the boiler specialists at Water Treatment Services review the management of industrial steam generating systems looking specifically at the impact of carryover, what causes it, why it needs to be managed and how to control it.
If your steam boiler or hot water heating systems are not running at optimum efficiency then you could be wasting more money than you think. Inefficient boilers and poorly performing heating systems can result in higher fuel costs, lower thermal performance, more down-time and increased maintenance bills. However, it is possible to improve performance and reduce these costs by improving the quality of the water which feeds into your boiler system. This is can be done using specialist boiler water treatment chemicals or some other way of purifying the water. In low pressure boilers, water purification and pre-treatment would usually involve ion-exchange. However, with high pressure boilers where the pressures required in the boiler are significantly higher, the quality of the boiler feed water needs to be much better, and this can be achieved using a reverse osmosis (RO) pre-treatment process.
This short article is about steam boilers. A typical steam boiler is formed as a closed vessel with in which water or some other liquid is heated to elevated temperatures. The water used in a boiler is not necessarily heated to its boiling point although most often it is. Once in operation the heated water or liquid exits the boiler system where it is used in various industrial processes or heating applications, including water heating, central or space heating, steam-based power generation, cooking, and disinfection and many more applications.
