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.
Take a 5T boiler, containing approximately 8,200 litres of water, the amount of caustic required to maintain a pH of 10.5 would be 0.7kg whilst at 12.5pH that rises to 69.1kg of caustic

Optimizing hot water systems with condensing boilers Note that the pH of the water in the closed loop system will remain the same as that in a noncondensing boiler. The optimum pH in the condensate is 3 to 4 in condensing boilers. so proper disposal of condensate is required. The condensate shall also be piped through an acid
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.
pH Species Present 4-5 HSO 3-7 HSO 3-and SO 3 2-(1:1) 8.5-9.0 SO 3-Because of the alkalinity and sodium found in most boiler feedwater and boiler water, sulfite ion is the species found regardless of the initial salt. In the high temperature/pressure and alkaline atmosphere of the boiler, sodium sulfite will decompose.

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.
A steam boiler is a closed vessel, generally made of steel, in which water is heated by some source of heat produced by combustion of fuel and ultimately to generate steam.
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.
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.

This condensate water is highly acidic (pH of 2) and could be dirty if the fuel is dirty or if the boiler needs servicing. If the vent pipe exits through a side wall rather than through the ceiling, the horizontal portion of the pipe should be installed at a slight upward angle so that any condensate water drains back to a condensate drain line
Selling house, boiler has no gas safety register certificate please help I (water) plumbed my combi boiler in myself in 2008 (all new rads with TRV's, mostly new copper pipe throughout house, programmable room stat, I then let the flue through the wall and mortered it in, and connected the condensate drain to the kitchen sink waste).
The boiler receives the feed water, which consists of varying proportion of recovered condensed water (return water) and fresh water, which has been purified in varying degrees (make up water).The make-up water is usually natural water either in its raw state, or treated by some process before use.
Phosphate hideout usually results in an increase of PO4 concentration and a decrease of pH during load reduction and in an increase of pH and decrease of PO4 concentration during the load increases. The severity of phosphate hideout is boiler, heat flux, temperature, pressure, and boiler cleanliness specific.
