Water and energy go hand in hand. It takes energy to pump, treat, heat, and cool water for boiler and cooling systems. Not only can optimizing water usage help minimize energy usage, but managing scale deposits, corrosion, and biofilms also play a role in energy demands.
Boiler and cooling water systems require substantial amounts of energy to run our modern-day world. Proper water management can help reduce and optimize these energy demands. Multiple strategies are available to help meet energy-saving objectives, including optimizing water chemistry, improved pretreatment, preventing scale deposits, reducing water waste, and equipment maintenance.
Impact of Cycles of Concentration
As described in Part 2 of this series regarding water conservation, a core concept to efficiently operate boiler and cooling water systems is “cycles of concentration.” The cycles of concentration measure the degree to which the dissolved-solid impurities in the makeup water are concentrated. If too low, energy, water, and treatment chemicals will be wasted. If too high, scale, corrosion, and other issues can reduce energy efficiency and decrease equipment life. Finding the best cycles of concentration for a particular boiler or cooling tower system helps optimize sustainability and costs of operation.
Boiler Energy Saving Strategies
Steam boilers burn fuel to turn water into steam for space heating, process uses, power generation, and more. The makeup water quality, degree of system control, and mass balance of waters within the system can directly impact energy efficiency. Since energy is required to heat boiler water, water savings strategies also reduce energy usage.
Cooling Tower Energy Saving Strategies
Cooling towers are used to remove heat from building HVAC systems and industrial processes. Maintaining clean heat transfer surfaces is important to maximizing energy efficiencies and sustainability.
Closed System Energy Saving Strategies
Closed heating and cooling loops are recirculating water systems where heat is added to one part of the system and then removed in another part. Energy efficiency is directly impacted by insulating deposits that form on heat transfer surfaces, such as chiller tubes and heat exchangers.
