Thermal Processing of Municipal Solid Waste


The 1970’s saw the emergence of the incineration systems that started the Waste-to-Energy movement. Remarkable, these systems still dominate the world marketplace today.

So what is a municipal incinerator and how does it work?

Join Walter Niessen for the first session in our 3-part Incineration Series exploring the current options in mass burn incineration systems, their design and operating components, their relationship to the basic characteristics of domestic solid waste, and the special characteristics of refuse derived fuel (RDF) based combustion systems.

In this presentation we’ll take a step beyond our Combustion Series to delve into the details of the current waste combustion and waste-to-energy systems dominating the marketplace. We’ll start our discussion with the fundamental characteristics of solid waste and their impact on combustion systems and air emissions. We’ll discuss the key handling properties of combustion systems and each system’s characteristics (Maximum Continuous Rating) and how these define incinerator operations. We’ll explore the details of current mass market waste combustion systems, their designs, their operating features, and applications, as well as mass burn incineration, refuse derived fuel (RDF), and densified RDF. Within this discussion, we’ll discuss the elements, applications, and alternatives for incinerator components and sub-systems, including: waste receipt, storage, and feeding systems; combustion alternatives (grates, hearths, and fluidizing beds); enclosures; ash and ash processing systems; air pollution control systems; RDF-type incineration systems; and modular-type incineration systems. And finally we’ll end our discussion with an overview of municipal waste combustion where it is today, and preview our next session discussing where it is going tomorrow.

Learning Objectives 
Attendees can expect the discussion and education of the following learning objectives.
