Growing emphasis on energy efficiency and conservation has led to increasing use of heat recovery equipment with incinerators. The most prominent energy recovery devices are the boilers in large municipal refuse incinerators, often referred to as waste-to-energy (WTE) or resource recovery plants, which generate steam to drive turbines for electric power generation. Heat extraction is also finding wider application in industrial incinerators used to dispose of chemical and other hazardous wastes. Boilers are by no means the only method for extracting energy from incinerator off-gases. Extensive use is made of gas/gas heat exchangers for preheating combustion air and waste streams, notably in sludge incinerators and thermal oxidizers. Other heat exchanger applications in incineration facilities include the coolers, condensers, and reheaters in air-pollution control gas trains and associated subsystems. This article addresses alloy selection for incinerator heat-transfer equipment. It discusses heat exchanger design configurations, construction materials, corrosion concerns, examples of material failures, and selection criteria for heat-resistant and corrosion-resistant alloys. The materials covered include stainless steels and nickel-based alloys. Nonmetallic materials (such as plastics, glass, graphite, and ceramics) are not covered because of their very limited use for incinerator heat-transfer applications.
