Using Steam Accumulators to Satisfy Fluctuating Boiler Steam Demand

Modern boiler plants are increasingly focused on energy efficiency, reducing their physical footprint, as well as minimizing capital and installation costs. Companies are striving to keep their total cost of operation as low as possible to remain competitive in the global economy. One of the challenges is having a steam supply that can handle large variations in demand. If the boiler is too small to handle peak demands, the plant cannot operate as designed. If the boiler is sized to handle short bursts of steam, the boiler may be oversized and have higher energy input versus output due to lower efficiencies at lower loads.

Types of Boilers in Industrial Water Treatment

Boilers and steam production are essential to our modern lives. Boilers are used in almost every industry from generating electricity to heating buildings and everything in between. Due to the diverse demands for steam production, boilers come in various types and sizes.

COVID-19:  A Partnership Approach to Water Treatment Is More Important than Ever

With the impact of COVID-19, the ongoing partnership between plant personnel and your water treatment provider is more important than ever. Water systems, such as cooling towers and boilers, are dynamic systems by design. In today’s environment, they may not be operating as consistently as before with entire processes or facilities being shut down with little warning and, just as quickly, started back up.

Deaerator Design and Operation

A deaerator preheats boiler feedwater and removes dissolved gases, especially oxygen and carbon dioxide. These gases are undesirable because they cause corrosion and increase treatment chemical requirements. 

Deaerators operate based on the reduced solubility of dissolved gases as temperature increases. For example, the solubility of oxygen decreases from about five ppm at 150ºF to about two ppm at 190ºF. Virtually all the free carbon dioxide gas is removed by increasing the temperature to greater than 170ºF.

The Value of Good Boiler Blowdown Control

In a steam boiler system, blowdown involves removing a portion of the concentrated boiler water and replacing it with feedwater, which is a mixture of condensate and makeup water.

Good blowdown control is a critical component of the boiler water treatment program.  Boiler blowdown is heated, treated feedwater that is sent to the drain instead of converted into steam. Blowdown is used to control the dissolved and suspended solids level in a boiler within the range necessary to minimize scale deposits and carryover.  Too much blowdown increases fuel, water, and treatment requirements.  Too little blowdown can cause scale deposits and wet steam (carryover)

A Quick Tutorial on the Mechanics of Steam Boiler Systems

Boilers are specialized mechanical devices designed to generate pressurized steam. Steam is an essential raw material that drives industry and commerce worldwide. From the electricity used to power our homes and run our plants, to the plastic and vinyl in our automobiles, the paints and wood in on our homes, and the preparation of the food we eat, steam is used to make our lives more comfortable and convenient.

Neutralizing Amine Use in Hospital Steam Boilers

Hospitals use steam boilers to meet a variety of needs including domestic hot water, space heating, food preparation, sterilization, and humidification. The use of water treatment compounds called “neutralizing amines” can be a source of confusion, especially where plant steam is used for humidification and sterilization. Recently updated standards provide clear guidance on neutralizing amine use in hospital steam boiler systems.
