Most boiler systems today burn natural gas as the primary fuel. Many systems are also set up to burn an alternate fuel if the natural gas supply is curtailed or cut off. In most cases, the alternate fuel is No. 2 fuel oil, a light distillate that is the same as diesel fuel.
Some industrial and utility boilers may use No. 6 oil as the alternate fuel. No. 6 is a heavy residual oil that must be heated to approximately 150oF to be easily pumped. If No. 6 oil were fed to a boiler that was set up to burn No. 2, the burner would not burn the fuel efficiently, and the unit’s combustion efficiency would decrease. No. 6 oil is not a good “fit” for a boiler set up to burn no. 2.
Just as the type and quality of the fuel affects a boiler system combustion efficiency, the type and quality of the water treatment chemical program has an impact on the overall efficiency of the boiler system. If the chemical treatment program is not a good fit for the system, overall efficiency can be reduced, with a corresponding increase in operational costs. In today’s uncertain economic environment, this can put a company or facility at a competitive disadvantage, even threatening its very survival. Continue reading
It’s time to shut your cooling system down for the winter. Don’t let all your hard work keeping the system running smoothly go to waste – follow these guidelines to assure that your system stays protected all winter long and is ready for a trouble-free start-up next spring.
In July our Legionella risk assessment partner, Environmental Safety Technologies, reported…“We have seen an increase in the prevalence of Legionella colonization throughout the United States. We are seeing a greater percentage of Legionella positive cultures and identifying more high risk sites than in our 20 year history.”
On August 28, 2012 MyHealthNewsDaily reported: “Outbreaks of Legionnaires’ disease have been reported by health officials in two major cities this summer: Eight people have died and 107 have been confirmed infected in an outbreak that began in mid-July in Quebec, and eight infections, including two deaths, occurred among the guests at a hotel in Chicago. The Chicago outbreak was announced Monday.
In Quebec, where the average of those who have died is 79, the outbreak’s source is believed to be water cooling towers. Towers are being inspected and disinfected with bromine, according to Canadian media reports.”
In Chicago the article states…”health officials said. Details about the deaths have not been released. There is no ongoing health risk to hotel guests, according to the Chicago Department of Public Health, although more cases may yet be reported because symptoms of the disease can occur several weeks after exposure.”

Cooling Tower Replacement can be a costly proposition and the average life expectancy of a commercial cooling tower, according to most manufacturers, is 15 – 20 years, before they need to be rebuilt or replaced. Many cooling towers were installed in 1980’s and are 30 years old now. If the integrity of the tower’s metal sump, sidewalls and distribution pans are relatively sound, but the fiberglass fill has deteriorated to the point where it needs to be replaced, there are many dollars ($) that can be saved versus the cost of replacement.
In a cooling tower fill media replacement, we completely remove the fill from each tower cell, angle grind and metal patch all metal surfaces, seal the seams, and re-coat internal, wetted surfaces with a two part epoxy coating, – Belzona Immersion Grade. Once the towers are refurbished you can expect another 15 -20 years of useful life expectancy at a fraction of the cost of replacing them with new towers.
An example of the dollar savings expected for refurbishing a tower vs. replacement is when Bond Water Technologies completely refurbished four (4) 200 ton cooling towers (800 tons total) at a cost of approx. $80,000.00 vs. the cost of new towers quoted at $100,000.00, plus installation costs. If you elect to buy new towers vs. rebuilding the existing ones, you also need to consider budgeting in the cost of a construction crane to lift them to the roof, after normal working hours or on a weekend, which would cost approx. $12,000 to $15,000 per day, plus the labor cost of the mechanical contractors installation, so you’re now looking at $200,000+ for this one example. We can verify these costs from actual proposals done compared to a new tower replacement cost quote.

Over the past 12 years we have completely refurbished many cooling towers in the MD/VA/DC area by dissembling them, re-coating and replacing the fill with “honeycomb” media,, which is more effective in the cooling process vs. vertical hung fill in most of the older towers. It also adds another 15 years of life expectancy to these older towers, and offers the additional benefit of making the towers easier to clean.

Rebuilding is particularly attractive if you have already invested in mechanical repairs, such as shafts, bearings, blower wheels, etc.

We believe there are two educational areas that are critical to the success any water treatment program. First, it is critical that your water treatment representative understand your specific program needs and that he participates in ongoing education and training. Second, and often overlooked, is client education. Your water treatment company should make sure that you and your staff understand the basic chemistry behind your water treatment program.
We believe that client education and ongoing Bond representative training are Continue reading
