Thermal efficiency is a major concern when dealing with large utility boilers. By using a regenerative air preheater, you can increase efficiency with the last-expensive heat recovery system that also has the ability to endure harsh environments and extreme temperatures. The largest hindrance to the air preheating system is air leakage, which can lead to problems such as fouling, corrosion, increased auxiliary power consumption, ammonium bisulfate plugging and higher pressure differentials. These can all lead to a loss of efficiency and in turn, money. An article by powermag.com discusses the necessity of air preheaters in this month's offerings:
"The air preheater is a critical, yet often overlooked, component of the boiler combustion air system. Evaluating and optimizing a heater's performance is difficult given how entwined it is with the entire combustion system and the lack of standardized calculation tools. Reducing leakage by using modern seal technology will improve combustion efficiency, maintain fan performance, and keep your downstream air quality control equipment operating within spec."
By implementing and maintaining high-quality and high-durability air preheaters, you can rest assured that your large utility boiler will give you the maximum output without losing time and efficiency due to air leakage-related wear and tear. In a time when the economy isn't so great, even those in the power generation industry need to tighten their belts and watch their pocketbooks whenever possible. So, invest in an air preheater today and start saving that revenue for more important things: like operation expansion!
