Mar 27 2003 · Instead of say 140*F water coming back to your boiler you've got make-up water out of the municipal system at 40*F. You've lost 100 BTU for every lb of water you didn't get back. If you're running 80% boiler eff you need to burn 125 BTUs of fuel just to get that lb of water
Jun 01 2017 · In boiler feedwater conditioning the hardness of water can cause the formation of scale on evaporative surfaces as well as excessive sludge or "mud" unless properly treated.
Why does my home have hard water? The hardness or softness of your water will depend on the region of the country you live in. 60% of homes in England and Wales receive hard water with The East Coast and areas around London very likely to have it. How can hard water affect my boiler? The limescale formed by hard water can cause problems in ...
Neutralizing amines are used in boiler water treatment to control condensate return line corrosion. The amines do not have any adverse effects on copper or copper alloys under normal treatment conditions where pH is maintained between 7.5 to 9.0 and where only a few ppm of amine are continuously added to the boiler water.
At a minimum boiler feedwater must be softened water for low pressure boilers and demineralized water for high pressure boilers. It must be free of oxygen and essentially free of hardness constituents and suspended solids. Recommended feedwater limits are shown in Table 1.
Answer: c Explanation: Hardness of water is due to the presence of salts of calcium and magnesium. Hard drinking water may have moderate health benefits but can pose serious problems in industrial settings where water hardness is monitored to avoid costly breakdowns in boilers cooling towers and other equipment that handles water.
Caustic soda (NaOH) is the only normal boiler water constituent that has high solubility and does not crystallize under typical boiler conditions. Its caustic concentration can be as high as 10000-100000 ppm. Careful control of boiler water chemistry can prevent caustic gouging. If
Alireza Bahadori PhD in Essentials of Oil and Gas Utilities 2016. 4.10.3 Water. The boiler water concentration in the steam drum should be specified in the job specification. Samples of water for testing should be taken from the continuous blowdown. Samples should
Pre-heating the feed water to achieve an ideal boiler feed water temperature will allow the boiler to run most efficiently as the heat input required to raise the temperature of the water up is reduced. The difference between 140°F and 180°F in boiler feed water temperature equates to about a 3-4% difference in boiler efficiency.
Dec 03 2019 · Boiler water treatment is the conditioning and treatment of boiler feed water with the purpose of meeting three objectives. In order for boiler water treatment to be maintained there must be a continuous heat exchange protection for high-quality steam and corrosion protection. Boilers are designed to heat fluid after which the vaporized or heated fluid will exit the boiler and be used for ...
At a minimum boiler feedwater must be softened water for low pressure boilers and demineralized water for high pressure boilers. It must be free of oxygen and essentially free of hardness constituents and suspended solids. Recommended feedwater limits
Look for a small boiler when purchasing a continuous fill as this heats quickly and maintains excellent pressure as the and steam for those Commercial and/or heavy cleaning jobs. A favorable design as the boiler normally remains 90% full at all times adding approximately 1 - 2 oz per injection of water into the boiler.
The phosphate-hydroxide boiler water treatment prevents hardness Condensate Water Treatment: Because Steam Boiler Pipes Are Dec 5 2013 Returning the condensate back to the boiler saves water but more boiler makeup water or using a water softener to remove hardness The amines do not have any adverse effects on copper or ...
If your house has a boiler water hardness levels are important. Extremely soft water with a high volume of flow rate can leave pits in the copper tubing of the boiler. Extremely hard water can...
