Thermal Processing of Domestic Solid Waste Part 1 of 2 Combustion Processes

Walter R. Niessen, PE, BCEE

This course attempts to answer the question: What is a municipal incinerator? In the early years of refuse incineration in the United States, incinerators were uncomplicated refractory furnaces equipped with metal grates (drawn in most respects from existing coal furnace designs) to move the waste into and through the burning chambers and with (looking back) incredibly simple controls and inefficient air pollution abatement. The furnaces were designed in a technical collaboration between the public works department of the owner city (county, etc.) their consulting engineer and the major component vendors (esp. the grate and/or boiler manufacturer). The 1970's saw the emergence of a new incineration concept: high pressure, waterwall boilers that produced superheated steam that was fed to turbo-generators for power generation (Waste-to-Energy or WTE plants) and equipped with sophisticated process control systems and costly, highly efficient air pollution control. This is the technology that dominates the existing inventory of incineration systems throughout the world.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
