to produce 1 ton of steam how many GCV of coal is required?
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
Petroleum is a crucial raw material in manufacturing, primarily used to produce fuels, lubricants, and various petrochemicals. These petrochemicals serve as building blocks for a wide range of products, including plastics, synthetic fibers, and rubber. Additionally, petroleum-derived substances are used in the production of solvents, adhesives, and coatings, making it an essential component across multiple industries. Overall, petroleum's versatility underpins the manufacturing of many everyday items.
The amount of fuel required to evaporate 1 kg of water in a spray drying tower varies based on factors such as the efficiency of the drying process and the type of fuel used. Generally, it takes about 1.5 to 3 kg of fuel to evaporate 1 kg of water, depending on the specific energy requirements of the system and operational conditions. Efficient systems may reduce this ratio, while less efficient ones may require more fuel.
The petroleum industry consists of so many different types of processes because so many different things can be made from petroleum.

Coal produces energy through combustion where heat is generated by burning coal in a furnace. The heat produced converts water into steam which drives a turbine connected to a generator, producing electricity. Coal is a fossil fuel that releases stored energy when burned, making it a primary source for electricity generation in many countries.
I'm currently benchmarking a number of plants in my company which produce steam for downstream processing. What is a typical kWh/kg of steam ratio I could set as a best practice target? Thanks Paul
Steam generators are being used in many coal plants. There it is used to fuel the engines that process newly found coal so that it may be refined and used.
Coal used in boilers does not usually require an MSDS, but many have probably been created by coal suppliers. Ask you potential coal supplier for a copy.
You can use many different things. some examples are: Bio-Fuel (still in development) Wind (not as reliable as coal) solar (doesn't produce as much energy as coal) hydro (doesn't produce as much energy as coal)
Coal power stations use coal as their primary resource to generate electricity. They also use water for steam production, cooling, and emissions control. Additionally, they require land for infrastructure and waste disposal.

There is lumber, produce, fish, oil, coal and many more.
Coal began to replace the wood in the 1800s because the wood became scarce in some places. in the 1900s coal replace wood as a chief energy source because of its many used such as the fuel for steam engines which powered the many railroad engines popular during the period, and fuel for the steam turbines used in the production for electricity.
magnetsMISHcoal is another example of energy sources that produce electricity in our homes daily through by burning after mine. Coal is a solid fossil fuel that formed in several stages as the buried remains of land that lived 300-400million years ago. Many people have been asking of how coal generate electricity , well it is very simple, '' the coal is first burned for mainly thermal or heat energy. . That thermal energy is used to boil water and to produce steam.. That steam is then forced through a high pressure tube called a steam line.. The steam then pushes a turbine to the electric wires which is very dangerous.. That turbine then produces electrical energy.that is all bout generating electricity. Now if you have any question or comments contact me on facebook or on twitter ,here is my name ''Amin yansaneh'' and my email [mraminy7@yahoo.com].thank you have a good time.
