Busting The Myths About Condensing Boilers | GreenMatch

With modern condensing boiler systems, only about one litre per hour of condensate is produced, which has the pH levels of between 3.5 and 5 - less than the cow milk acidity levels. If a proper drain pipe is installed, then one has no reasons to worry about it.


Fire tube or "fire in tube" boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam circulates. (Refer Figure 2.2). Fire tube boilers, typically have a lower initial cost, are more fuel efficient and easier to operate, but they are limited generally to capacities of 25 tons/hr and pressures of 17.5 kg/cm 2.

What is Alkalinity of Water? - Water Treatment Basics

Alkalinity of water means acid neutralization capacity of water. When you add acid in water (adding H + ions) water absorbs H + ions without showing significant change in pH. Mainly, it is due to carbonate, bicarbonate & hydroxide ion present in water or the mixture of two ions present in water.

Understanding Alkalinity | Treatment Plant Operator

If the water contained only the exact amount of alkalinity required to neutralize the acids, there would not be enough alkalinity remaining to protect the final pH value from falling if any additional acid were formed or added downstream. Biological processes like nitrification and anaerobic digestion rely on alkalinity.

Technical - Raypak

Consider two copper finned tube boilers, both rated at 199,000 BTUH input, both with 1/7 HP circulating pumps, both connected to 80-gallon storage tanks. The only difference between the two systems is that Boiler A shuts down the pump when in standby mode while Boiler B pumps away continuously.

Water Quality - Slantfin

The lower the pH reading the more acidic the solution; the higher the pH the more basic the solution. The pH scale ranges from 1 to 14 with a pH of 7 being neutral. The pH of a system has a huge effect on the life of the system. Variations in pH can indicate a variety of problems and cause damage to the system components.
