Sea water, as from oceans, is salty. If used in a boiler the salt will deposit as scaling, which is a bad thing. It's also more corrosive, so the boiler and all associated pipework will rust out faster.
A boiler in a coal power station is responsible for converting water into steam. The coal is burned in the furnace of the boiler, producing heat which is used to generate steam. This steam is then used to drive a turbine, which spins a generator to produce electricity.
Boiling water will not remove oxygen from boiler water; it will actually deaerate the water, reducing the dissolved oxygen content. Oxygen removal from boiler water typically relies on mechanical deaeration processes or chemical treatments.
The pH value in boiler feed water is typically maintained between 8.5 and 9.5. This range helps to prevent corrosion and scaling in the boiler system. Regular monitoring and adjustment of pH levels are important to ensure the proper functioning and longevity of the boiler.
Morpholine is often preferred over ammonia for dosing in boiler feed water because it has lower volatility, lower potential for corrosion, and it offers better pH stability. Additionally, morpholine provides effective protection against both acidic and alkaline corrosion in the boiler system, making it a more versatile and reliable option compared to ammonia dosing.
A scum forms when soap is used in hard water. This occurs because the calcium and magnesium ions in the hard water react with the soap to form insoluble salts, which precipitate out as a scum.
It shouldn't be ideally, as hard water deposits limescase (a solid) in the boiler
An electric water boiler is a small appliance used to boil water. This can then be used for hot drinks or in a recipe that requires boiling water. An electric boiler is also helpful if the water coming from the tap contains contaminants, because boiling the water will eliminate them.
Mineral deposits from use of hard water.
Hard water is softened before being used in boilers to prevent scale formation, which can accumulate on the boiler's heat exchange surfaces and reduce efficiency. Scale buildup can lead to overheating and potential damage to the boiler, increasing maintenance costs and reducing its lifespan. Softening the water removes minerals like calcium and magnesium that contribute to hardness, ensuring smoother operation and improved energy efficiency. Additionally, softened water helps maintain better heat transfer and reduces the risk of boiler failure.
One function: to safely heat water. Whatever the resulting hot water or steam is used for is not a function of the boiler, but the system it is connected to.
Some older ships used the power of steam to propel them through the water. A boiler is used to heat water to make steam which is passed to a steam engine which turns the propeller. In ships like the Titanic the boiler was fuelled by coal but later steam ships used gas to heat the water.
The most common boiler problems often arise because the boiler is not maintained. One is that in hard water areas the element is furred up and so it is not able to heat up the water as it should. Another is that the insulation is shifted and so no longer covers the boiler and keeps the heat in.
Water is a power supply because it is used in power plants. The water is inside the boiler and the boiler is heated to make the water turn into steam. The steam is what makes the power.
scales are actually formed by deposit of calcium and magnesium that make water hard
Boiler scale removers are chemicals or descaling agents used to remove mineral deposits, such as calcium and magnesium, from the interior surfaces of boilers. These deposits can reduce the efficiency of the boiler and potentially lead to equipment damage if not removed. Scale removers help to clean and maintain the boiler for optimal performance.
it is used to burn the fuel(coal,usually) with primary and secondary air.the burning coal is then used to heat the water in the boiler to produce steam.
only water is used in boilers to reduce the cost. and if other liquid like petrochemicals will be used than the cost will be more and there will be the higher risk because if the boiler bursts than it will cause more damage than water boiler.
