Energy from waste
Hot water | Steam | Electricity
One of the most significant advantages of waste-to-energy incineration plants is the generation of cleaner and more sustainable energy. Traditional waste disposal methods, such as landfilling, contribute to the release of greenhouse gases and air pollution, which can harm the environment and human health.
In contrast, waste-to-energy incineration plants utilise advanced technologies to convert waste into energy. The process involves controlled combustion of waste materials, such as municipal solid, industrial, or agricultural waste, in specially designed chambers. This combustion process not only reduces the volume of waste but also harnesses the energy released during the process.
By converting waste into energy, these incineration plants offer a cleaner alternative to traditional forms of energy generation. The combustion process is carried out under strict environmental regulations and utilises sophisticated air pollution control systems. These systems capture and treat harmful emissions, such as particulate matter, heavy metals, and dioxins, before they are released into the atmosphere.
Electric generation
ORC’s are to be used when energy recovery in the form of hot water energy recovery cannot be utilised.
An ORC system allows the energy in the hot water to be transferred to electricity by using the hot water generated from the waste heat recovery boiler to heat a working fluid within the ORC.
The ORC works according to the same principles as a normal steam turbine. The main difference is that the working medium makes it possible to use lower quantities or low-temperature waste heat to generate electricity.
The basic working principle is as follows:
-
The heat from the hot water causes the working media to evaporate at high pressure.
-
The vapour is expanded to low pressure in a turbine, generating electricity or mechanical work.
-
The low-pressure vapour is condensed using cooling water and is pumped back to the high-pressure side.
