  1. 1. Investigations of Chlorine-Induced High Temperature Corrosion of Steels

    Författare :Nicklas Folkeson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sulphur; alkali; chlorine; field exposures; HCl-induced corrosion; high temperature corrosion; deposits.; chloride-induced corrosion; waste; 310S; HCl;

    Sammanfattning : The high corrosivity of the fireside environment in waste and biomass fired boilers is commonly attributed to the presence of chlorine-containing compounds. Chlorine-induced high temperature corrosion is not well understood, however. LÄS MER

    Sammanfattning : The effects of greenhouse gas net emissions on global warming, stricter legislation on waste handling, and the pursuit of ever cheaper heat- and power production are all important factors driving the introduction of complex fuels in incineration plants. However - without fundamental knowledge regarding ash transformation, corrosion control, and materials selection – this introduction of potentially economically and environmentally beneficial fuels, might instead cause economic loss and environmentally adverse effects.

    Sammanfattning : The use of renewable wood-based fuel has been increasing in the last few decades because it is said to be carbon neutral. However, wood-based fuel, and especially used wood (also known as recycled wood or waste wood), is more corrosive than virgin wood (forest fuel), because of higher amounts of chlorine and heavy metals.

  4. 4. Chlorine Induced Corrosion in Biomass and Waste Fired Boilers: Laboratory and Field Investigations

    Författare :Nicklas Folkeson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; austenitic; chloride; biomass; high temperature corrosion; ferritic; waste; steel;

    Sammanfattning : The fireside corrosion in biomass and waste fired boilers is widely believed to arise from the presence of chlorine-containing compounds in the fuels. Although many researchers have studied the influence of such compounds on the high temperature corrosion of various steels, the mechanisms underlying chlorine-induced corrosion are still poorly understood.
