What is the function of anti-priming device in boilers?
The anti-priming device in boilers is designed to prevent the carryover of water into the steam system. It helps to ensure that only steam, and not water droplets, is delivered to the steam lines, which can lead to efficiency losses and potential damage to equipment. By maintaining proper water levels and controlling the steam quality, the device enhances the overall performance and safety of the boiler system.
What is supercritical boiler?
The following extract taken from an article by Ingo Paul in Energy Issues No 19 April 1999 published by the World Bank [external link] briefly describes the difference between a subcritical and a supercritical boiler. "Supercritical" is a thermodynamic expression describing the state of a substance where there is no clear distinction between the liquid and the gaseous phase (i.e. they are a homogenous fluid). Water reaches this state at a pressure above 22.1 megapascals (MPa) The "efficiency" of the thermodynamic process of a coal fired power (sic) describes how much of the energy fed into the cycle is converted into electrical energy. The greater the output of electrical energy for a given amount of energy input, the higher the efficiency. If the energy input to the cycle is kept constant, the output can be increased by selecting elevated pressures and temperatures for the water-steam cycle. Up to an operating pressure of around 19 MPa in the evaporator part of the boiler, the cycle is sub-critical. This means, that there is a non-homogeneous mixture of water and steam in the evaporator part of the boiler. In this case a drum-type boiler is used because the steam needs to be separated from water in the drum of the boiler before it is superheated and led into the turbine. Above an operating pressure of 22.1 MPa in the evaporator part of the boiler, the cycle is supercritical. The cycle medium is a single phase fluid with homogeneous properties and there is no need to separate steam from water in a drum. Once-through boilers are therefore used in supercritical cycles. www.whizkris.com
What is the use of super critical boilers?
Supercritical boilers are used in power plants to generate steam at pressures and temperatures above the critical point of water, resulting in improved thermal efficiency and reduced emissions. By operating at supercritical conditions, these boilers eliminate the distinction between liquid and vapor phases, allowing for more efficient heat transfer and energy production. This technology helps optimize fuel use and minimize environmental impact, making it a preferred choice for modern coal and biomass power generation.
Is a boiler a chlorifier?
No, a boiler is not a chlorifier. A boiler is a device used to heat water or produce steam for heating or power generation, while a chlorifier is a system designed for the disinfection of water through the addition of chlorine. The two serve different purposes in water treatment and heating processes.
Water is heated and changed to STEAM?
That is called boiling. And it is something you can see and observe, but it is something tht is chemically relted and so it is a chemical change.
How steam boilers work?
Steam boilers work by boiling water to generate steam. The steam then is used to heat the engine.
Are hot water boilers similar to small steam boilers?
Yes, hot water boilers and small steam boilers are similar in that both are used for heating purposes, but they operate differently. Hot water boilers heat water and distribute it through pipes for heating spaces, while steam boilers generate steam that can be used for heating or powering equipment. Their design and operational pressures also differ, with steam boilers typically operating at higher pressures than hot water boilers. Despite these differences, both types of boilers serve important roles in heating systems.
What did they burn to heat water in the ships boilers to make steam?
Coal
What is steam accumulator?
A steam accumulator on some once through boilers, with no steam/water drum, is a device similar to a steam separator, which separates the steam and water before the steam is fed to the steam header.
What is the difference between a steam boiler and steam generator?
boiler use many type of working fluids like water, Mercury, liquid sodium, etc., but steam generator works only with water as working fluid. hence all steam generator are boilers but all boilers are not steam generators...
What is steam genarator?
A steam generator is simply a heat exchanger that is commonly used to change water into steam. This can also be described as low water content boilers.
Why steam boilers are coil type boilers?
All boilers are not coil type think of the pork chop steam boilers AKA cast iron sectional
What is the difference between a hot water generator and steam boiler?
boiler use many type of working fluids like water, mercury, liquid sodium, etc., but steam generator works only with water as working fluid. hence all steam generator are boilers but all boilers are not steam generators...

What are the 2 main types of boilers?
Fire tube and water tube. Steam Boiler and Water Boiler.
What creates steam?
Steam is created when water is heated to its boiling point, causing it to evaporate into a gaseous state. This can happen in various ways, such as boiling water on a stove or heating water in a boiler.
