“…Prism ensures homogenous injection of secondary air via multiple nozzles that are on the prism sides and boiler walls. This supply ensures that there is high turbulence and mixing of waste with excess air which prevents the deposition of ash and also facilitates sulphation process to occur [52], which in turn reduces the corrosion impact [47]. In addition, the prism results in a uniform distribution of flue gas speed, temperature and oxygen, thereby preventing the creation of hot spots within the boiler [32].…”

“…In addition, the prism results in a uniform distribution of flue gas speed, temperature and oxygen, thereby preventing the creation of hot spots within the boiler [32]. Moreover, the prism removes heat from the combustion zone, and reduces the temperature, which then reduces the volatilization of alkali chlorides, leading to generation of less chemically corrosive deposits [47,52].…”

MSW generation has increased drastically throughout the world surpassing the ability of municipalities to handle it. Treating waste in incinerators with energy recovery have been opted as an environmentally preferred method of waste management. However, waste incineration result in inefficient energy generation. The objective of this chapter is to provide a summary of issues leading to inefficient treatment of MSW and the potentials for improving it. High-temperature corrosion and ash-deposition on heat exchange surfaces are the major causes of inefficiency during waste incineration. Optimizing the operating conditions during incineration reduces the deterrent corrosion and ash deposition problems. The operating conditions can be optimized by conducting a kinetic modelling which identifies the conditions that reduces corrosion rate. These conditions are moisture content ~10 vol.% and SO2 ~250 ppm. Also, use of ecotubes and sergher-boiler prisms ensures high turbulence and mixing within the boiler which reduces the ash problems, thereby improving the incineration efficiency. Sorting of MSW using max Al robotic sorter and removal of alkali chlorides in waste through the use of sink-float process, centrifuge and hydrocyclone separation technologies lowers chlorine load hence lowering the severe ash problems and proves to be beneficial in improving the efficiency of treating MSW in incinerators.

“…The waste is fed into a gasification reactor at a standard condition where it is converted in syngas and granulate that can represent a byproduct. The feed of the plant (Refused Derived Fuel or RDF) (Agovino et al, 2016;Rispoli et al, 2021a) has a flowrate of 127 t/h and it is modelled as a non-conventional component, based on the analyses in the Table 1 (Grillo, 2013):…”

The objective of the paper was to analyse possibilities and advantages of energy recovery from municipal solid waste during the thermal treatment in boilers with a moving grate system. The state of the art of Waste-to-Energy (WtE) boilers was investigated mainly by reviewing papers published in scientific journals and at conferences but also by taking into consideration reports from research institutes. The article shows the main aspects that determine the popularity of this type of boilers as well as new solutions which greatly improve the process of thermal treatment of waste. It proves that waste incineration boilers based on the moving grate technology prevail mainly because of its simplicity, reliability and effective energy generation to which special attention was paid. Additionally, the article mentions how WtE boilers are designed and operated to incinerate municipal waste with a great variation in composition with simultaneous notable energy recovery and low environmental impacts. Contemporary development of the Polish WtE infrastructure can be a very important factor influencing the national municipal waste management together with renewable energy and energy efficiency policies.
