Waste-to-energy (WtE), also known as energy-from-waste (EfW), is the process of generating electricity or steam from municipal or industrial waste—essentially anything that has BTU content. The current global trend is to minimize landfilling, and the methods to do so are a combination of recycling programs and WtE incineration.

The process starts by sourcing and transporting waste streams to the incineration site. Exact procedure and vessels vary greatly, but their commonality is the combustion of the waste material in the presence of steam heat exchanger tubes. Steam is then used either by processes requiring heating or to turn a steam turbine to generate electricity. Vessels are refractory lined to protect structural as well as heat-exchanging components from heat and chemical/alkali attack.

Refractory choices are dependent on the unit design, location within the unit, and most importantly the composition of the waste material being incinerated. Common refractory challenges include:

  • Alkali and other chemical attacks
  • Thermal shock due to the loading of a “cold” fuel source
  • The use of water jets to regulate vessel

HarbisonWalker International is a strong supporter of WtE technology. HWI has solutions for any waste stream and preferred installation type. For example, within our phosphate-bonded plastic refractory line, we have a range of products, including those with varying amounts of alumina content, products that contain chrome, and products that contain high levels of silicon carbide, like ECLIPSE-80 GR PLUS. We can tailor our refractory offerings to your needs.
