The primary function of a utility boiler is to convert water into steam to be used by a steam turbine/generator in producing electricity. The boiler consists of a furnace, where air and fuel are combined and burned to produce combustion gases, and a feedwater tube system, the contents of which are heated by these gases.Learn More
Mar 17, 2015 · Step 5: Determine Fuel Energy. Fuel Energy = Boiler Energy / Combustion Efficiency; Assumptions. Deaerator provides feedwater near the boiling temperature for the deaerator's set operating pressure. (Saturated Liquid) Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the Learn More
Boiler feedwater is an essential part of boiler operations. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used it is then dumped to the main condenser. From …Learn More
Some feed water treatment chemicals, such as chelants, if not properly applied, can corrode feed water piping, control valves, and even the boiler internals. While the elimination of oxygen from boiler feed water is the major step in controlling boiler corrosion, corrosion can still occur. An example is the directLearn More

Dec 21, 2020 · The heated water generates high-pressure steam used for the production of Electricity. To increase the economy of the boiler, exhaust gases also find use to preheat combustion air blown into the burners and to warm the feed water supply in an economizer. Types of Water Tube Boilers. Here is a list of water tube boiler typesLearn More
Boiler Feed Water for Power Generation. High purity feed water is required to ensure proper operation of steam generation systems and reduce the use of boiler chemicals and fuel costs due to less frequent blowdown requirements. Using treated water with lower levels of impurities also prevents scale buildup and reduces corrosion rates in the boiler.Learn More
This video explains the Boiler Feed Water & its specifications. The topic falls under the Engineering Chemistry course that also provides information on the Learn More
Answer (1 of 6): I think the question makes a common misunderstanding. Steam boilers for power or heating use highly purified and chemically conditioned water, which is largely recycled, so water use is not a serious environmental issue. The steam produced is condensed and used again. A small amoLearn More
Boilers are used in power plants to generate steam which is in turn used to generate power. The water supplied to the boiler which is converted into steam is called boiler feed water.The steam produced in a boiler is condensed after use and is returned to the boiler as recovered condensate and made-up with additional fresh water or makeup water. Learn More
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 …Learn More
Jan 08, 2021 · Hot water boilers are generally used for heating, but there are fewer production processes that require the use of steam. First of all, in terms of fuel consumption, hot water boiler heating saves Learn More
The main features of a gas boiler that use the most electricity are the central heating pump and the boiler fan. Some older boilers may use a gravity-fed system. These systems rely on gravity to pump water around the radiators without needing an additional pump. However, many modern heating systems will use a central heating pump. These devices use electricity to operate, however they only require …Learn More
Sep 28, 2020 · A condensing boiler utilizes a heat exchanger to heat the water before it is transported to the radiators and one to reheat water as it is returned. This allows them to use the energy in exhaust gases to have the water preheated before it returns to the boiler, making it …Learn More
Sep 06, 2001 · 4. Convert the pounds of steam per hour into the boiler kW requirements. Since saturated steam tables are based on feed water at 32 deg F, a simplified kilowatts-per-pound-of-steam table is used to determine a correction factor for feed water at some higher temperature (Table 3).Learn More
