Condensate return water treatment: These chemicals regulate the pH of the condensate from the boiler returning to the system. They also protect pipes from corrosion. Boiler inhibitors : These are all-in-one packages of chemicals that treat the boiler water to control pH, stop foaming, prevent corrosion and protect against scale and pitting.

Sugar is an excellent example of an organic which, when returned in a large quantity, can cause rapid loss of boiler water alkalinity and reduce pH of the boiler water to 4.3 and lower. Most sugar refining plants maintain standby pumping systems, to add caustic soda to neutralize these acids as quickly as possible.

This ratio depends on two factors: boiler pressure and boiler water pH. The value of the ratio increases almost logarithmically with increasing pressure and decreases with increasing pH. If the silica enters the boiler water, the usual corrective action is to increase boiler blowdown, to decrease it to acceptable levels and then to correct the condition that caused the silica contamination.

If the feedwater has dissolved iron, which may be either from condensate or from the make up water or generated within the boiler will again lead to foaming. If the feedwater contains suspended impurities then also carry over will be high.

Scale formation within a boiler is controlled by one of four chemical programs: coagulation (carbonate), phosphate residual, chelation or coordinated phosphate. Coagulation Programs In this process, sodium carbonate, sodium hydroxide or both are added to the boiler water to supplement the alkalinity supplied by the makeup, which is not softened.

K. Sipilä, in Advanced District Heating and Cooling (DHC) Systems, 20163.6.1.6 Gas cooling In the gasification of solid REF, impurities that cause boiler corrosion are transferred to the product gas. Therefore, the product gas is cooled from 900 C to about 400 C so that materials causing corrosion, such as alkali chlorides, turn from gas into solid particles.

Gravity one-pipe air-vent system—One of the earliest types used, this method returns condensate to the boiler by gravity. This system is generally found in one-building-type heating systems. The steam is supplied by the boiler and carried through a single system or pipe to radiators, as shown in Figure 12.10 .

Testing Boiler Condensate. Steam condensate is like money in the bank for boiler owner-operators. It has already been purchased and treated, making it most desirable for reuse as feedwater. The more condensate returned to the boiler, the less make-up water needed. Its heat content, when recycled back to the boiler, generates energy savings.
