Waste Heat Steam Boiler

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.

Steam generation

Steam has many potential applications within an industrial process or for heating purposes, and we can design any waste incinerator with the technology to convert waste heat into this valuable resource.

​

 

Heat is indirectly recovered from the exhaust gases of the incinerator by passing them either through a gas tube heat exchanger or through a radiant tube boiler.

​

 

Energy is exchanged between the gases and water to produce steam. If the intention is that the steam is used for energy generation, such as electricity production, it is heated further in a superheater to produce a dry steam to drive a turbine / generator. Economisers are fitted to the boiler outlet to recover additional energy from the flue gas.
