Crude, diesel fuel oil and natural gas are frequently combusted in gas turbines as well as boilers. The waste heat from a gas turbine, in the form of hot exhaust gas, can be used to raise steam, by passing this gas through a heat recovery steam generator (HRSG), the steam is then used to drive a steam turbine in a combined cycle plant that improves overall efficiency. In case no gas turbine boilers are usually used, where are fired by either crude or diesel fuel oil. The hot water inside the boiler get evaporated and converted to pressurized steam which used to run the steam turbine.
Power stations burning coal, fuel oil, or natural gas are often called fossil fuel power stations. Some biomass-fueled thermal power stations have appeared also. Non-nuclear thermal power stations, particularly fossil-fueled plants, are sometimes referred to as conventional power stations.
Different kinds of power stations
- Heat (thermal) energy generated from: Fossil fuels; Coal, petroleum, natural gas, solar thermal energy, geothermal energy and nuclear energy.
- Potential energy from falling water in a hydroelectric facility.
- Wind energy.
- Solar electric from solar (photovoltaic) cells.
- Chemical energy from: fuel cells and batteries.
The common fuels used in power stations include:
- Fossil fuels (coal, oil and natural gas)
- Nuclear fuels (uranium and, sometimes, plutonium)
- Renewable biomass (wood, straw and manure).
There are many kinds of thermal power stations machines as following;
- Diesel or gas engines;
- Small capacity gas turbines;
- Small capacity steam turbines
- Large capacity gas turbines;
- Large capacity steam turbines;
- Combined cycle of gas and steam turbines;
In ChemKleen business we are dealing with the diesel generators and or gas engines in building the small capacities power stations.
ChemKleen environmental scope of works is engineering, design, selection, delivery, installation, testing, commissioning, handing over and warranties the small size of power station.
