By far, the most expensive part of any boiler operation is fuel usage. To maximize heat transfer efficiency, it is imperative that the heat transfer surfaces stay clean.
Boiler water treatment is important for both safety and efficiency. As water evaporates into steam, it leaves behind impurities as deposits. Over time, these deposits build, decreasing steam generation rates. Without proper maintenance, this can lead to mechanical failure or even boiler explosions.
Boiler water treatment is critical to ensuring your boiler is operating as efficiently as possible, and no proper water treatment program is complete without a thorough understanding of the feedwater setup. A crucial step in preparing the feedwater for the boiler is preheating and deaerating the water in a separate vessel directly upstream of the boiler.
Feedwater tanks are heated storage tanks that do not have a specific deaerating section and operate at atmospheric pressure. In addition to being a feedwater reservoir, these tanks also act as condensate receivers, cold-water makeup locations and as a point for chemical injection.
Boiler lay-up is performed for many reasons but always with one main objective: to keep the boiler in good condition until it is time to put it back into operation. Vapor-phase corrosion inhibitors can help make this process safer and easier.
Boilers used for steam and energy production, or operations such as washing, are sometimes taken offline for inspection and maintenance, or kept for backup use. Another common time for boilers to be out of service is during shipment or while in storage at a new plant still under construction.
Improve your steam heating return on investment by optimizing the cycles of concentration, enabling a higher condensate return. Other strategies include producing higher quality makeup water and implementing remote continuous operation and monitoring.
Process heating accounts for a large portion of the energy demand in industrial plants, and the fuel that is required to run a steam plant represents a costly and necessary reoccurring expense.
Hydraulic and solenoid metering pumps along with filter feeders can be go-to technologies for injecting and dosing the chemicals that are critical in delivering optimal boiler operation.
No question: water is the lifeblood of boiler operation. Yet, water can be rife with impurities that can result in rust, scale, corrosion and, ultimately, boiler failure.
A no-cost webinar on November 18 at 2 p.m. will provide a basic explanation of a process steam system from the generation of steam in the boiler to its transport to the various energy users.
A gas-fired power plant in the Samara area of the Volga region of Russia saved 1.3 million gallons of water annually and reduced water consumption enough to save $120,000 annually.
U.S. Water Services, Cambridge, Minn., is always looking for new tools to make a facility’s boiler system more efficient. One tool is a boiler inspection, which is a thorough checkup of internal and external boiler components in addition to the mandated inspections.
