29/5/2014 · BOILER ACCESSORIES Feed pump Injector Economizer Air pre-heater Superheated Steam separator 9 10. FEED PUMP Its a pump which is used to deliver feed water to the boiler. The appliances in common use for delivering the feed-water into
Any boiler which does not exceed any of the following limits: 405 mm inside diameter, 1,065 mm overall length of outside to outside heads at center 1.85 mm of water heating surface, 7.03 kg/cm^2 maximum allowable pressure. Fitted on scotch boilers, and supplies
How boiler feedwater deaeration is done. Water at 70°F could contain oxygen at 8.6 ppm and water at 150°F could contain oxygen at 4.3 ppm. Oxygen content of 7 ppb is generally accepted by the ASME, but your boiler supplier should specify what level is ideal for operating their equipment. Heat is the most common method for removing oxygen.
25/5/2020 · Boiler thermostat: this should be set at 65 degrees, to enable it to deliver water of 60 degrees (see above). While radiators will get hot quicker if the boiler thermostat is set at a higher temperature, the boiler may not condense, which will reduce its efficiency by 10-20%.
Low quality water that contains impurities and gases will deliver lower heat transfer, cause overheating, boiler damage, boiler leaks and costly cleaning. As water is heated to steam and circulated throughout the system, it must be resupplied from returning condensate, or fresh water must be added to maintain the required steam pressure.
18/4/2020 · These valves are also referred to as pressure reducing boiler feed valves or feed water pressure regulators. Regardless of what they are called, their function remains the same; that is, to deliver water to·:the boiler at the required pressure. To perform this func tion
The water is heated in the boiler (4) to produce hot water and/or steam that can be used directly in the process or sent to a heat-exchanger (5). The heat-exchanger transfers the heat from the circulating boiler water to another media such as the product, as indirect process use.
Boiler feedwater pumps use high pressure to transport water into boilers. As a result, a boiler feed pump is designed to deliver feed water into the boiler system under extremely high water pressure. Gear pumps are small and simple compared to other pumps.
27/5/2016 · It is used to heat the feedwater by the utilization of heat from the hot fuel gases before it leaves the chimney. A economiser improves the economy of the steam boilers. 4. Feed pump It is used to deliver water to the boiler.
