Boiler water treatment has long been an important factor in the operation of boilers. As the power plant operating pressures increase, water quality requirements also become stricter. With the current units operating at very high pressures, the water quality requirements get more stringent. Continuous improvements and changes in the methods of maintaining water quality, understanding the corrosion mechanisms, and the development of new chemicals have resulted in a more economical and efficient water regime management.
Reasons for Boiler water treatment:
This Reverse Osmosis System provides boiler feed water treatment to high-pressure boilers at a power plant. The system is specifically designed to adjust for cold feed water during winter months without any loss in production capacity.
There are also chemical treatment requirements to minimize the corrosive effects of water in boiler feed water and is just as important as the mechanical equipment required for proper maintenance and operation. This can be discussed with a chemical manufacturer.
Types of mechanical boiler water treatment.
Mechanical water treatment: Softeners remove the hardness inherent in all water sources, as untreated water hardness leads to scale. Proper water softener operation improves boiler heat transfer and efficiency, reduces thermal stress on the boiler and minimizes blow-off losses, resulting in less water, chemical and fuel consumption.
Boilers can also lose efficiency from scale. Scale is a buildup of dissolved impurities, such as calcium, magnesium, phosphate, silica and iron oxide. These impurities concentrate in the boiler water due to evaporation. Only pure water evaporates as steam, leaving dissolved minerals behind. Scale on heating surfaces reduces heat transfer and is detrimental to boiler efficiency.
There are several types of mechanical equipment used to improve boiler feed water. Ddealkalizers, demineralizers and reverse osmosis. Dealkalizers regenerate like softeners, and caustic is added to drive reactions. They also increase conductivity of makeup water while reducing alkalinity. Reverse osmosis uses pressure and a membrane to filter out hardness, alkalinity and other ions.
Though it used to be expensive, reverse osmosis has now become more viable and often pays for itself in a short time period by reducing blow down and chemical use.
This Reverse Osmosis System provides pure water to high-pressure boilers for a large automobile tire manufacturer. Purified water from this system typically has less than 10 us/cm conductivity. This type of boiler water treatment improves the boiler efficiency, by minimizing scaling and improving heat transfer.
