Used Technologies. At the core of the process there are rotary kilns. The first ones were long wet kilns, in which the whole thermal process took place. Introducing the dry process, the optimisation led to techniques which allowed drying, preheating and calcining to take place in a stationary installation rather than in the rotary kiln. The rotary kiln consists of a steel tube with a length-to-diameter ratio of between 10:1 and 38:1. The tube is supported by two to seven (or more) support stations, has an inclination of 2.5 to 4.5% and a drive rotates the kiln about its axis at 0.5 to 5.0 revolutions per minute. The combination of the tube’s slope and rotation causes material to be transported slowly along it. In order to withstand the very high peak temperatures, the entire rotary kiln is lined with heat resistant bricks (refractories). All long and some short kilns are equipped with internals (chains, crosses, lifters) to improve heat transfer. The fuel introduced via the main burner produces the main flame with flame temperatures of around 2000°C. For process optimisation reasons, the flame has to be adjustable within certain limits. In a modern indirectly fired burner, the flame is shaped and adjusted by the primary air (10–15% of total combustion air). Transient build-up of material can occur around the inner surface of the kiln depending on the process and raw materials, etc. These are known as rings and can occur at the feed end (gypsum rings), near the sintering zone (clinker rings) or at the product exit end (ash rings). The latter two types can break away suddenly and cause a surge of hot, poor quality material to leave the kiln, which may then be reprocessed or have to be rejected as waste. The cyclones and grates of preheater kilns may also be subject to the build-up of material which can lead to blockages. The table below summarizes the different types of kilns with their most important characteristics.17,18,19,20 Their electricity demand is about 90 to 150 kWh/t of produced cement. In turn, Figure 17 from the World Business Council for Sustainable Development (WBCSD) shows, the clinker production from 1990 to 2016 for each type of kilns described21.‌‌‌ While the most used kiln is the Cyclone, there is also another type of kiln that has not been shown in the table since it is less and less widespread because it has a production of only 300 tonnes/day and is defined vertical kiln or shaft kiln. A few shaft kilns are used for cement production in Europe. Kilns of ...

Used Technologies. As it is shown in the paragraph 5.3.3.2 5.3.3.1, the technologies used for steelmaking are mainly three: Basic- Oxygen Furnace (BOF), Open-Hearth Furnace (OHF) and Electric-Arc Furnace (EAF). The BOF and OHF technologies have both an integrated route with the Blast Furnace that is used for ironmaking, while the EAF technology can have a non-integrated route thanks to its steelmaking feature that allows to produce steel also directly with steel scrap (see figure aside47). Below, the technical features of the three different steelmaking technologies are described:

Used Technologies. There are two types of kilns for firing pigments. The first is the rotary kiln (adapted for firing pigments) similar to the concept used for cement, and the other is the innovative vertical kiln. However, there are other processes currently being tested for pigments firing, that have the potential to reduce emissions and save energy. The following table lists these new pigment firing technologies with the advantages and disadvantages compared to traditional technology. Type of Kilns Advantages Hindrances Rotary Kiln • Fast firing cycles (< 1h) • Higher temperature • Energy savings • Higher automation • Fast firing cycles (< 1h) • Higher temperature • Energy savings • Higher automation Open system:• Reduced effect of mineralisers• No efficient fluid mass transport Possible just where: • Solid state reactions predominant • Reactions kinetics is fast Vertical Kiln Fireless Processes Advantages Hindrances Microwave • Energy savings • Low temperature • Better control on synthesis • Better control on particle size • Slow kinetics• Uncomplete reactions• Too fine particle size distribution• Accelerate dissolution in glazes Mechanosynthesis Milling of raw materials inside a very high energy mil (vibratory, planetary, attritor) for long time. The final phase composition is achieved without firing, but only through mechanical alloying • Easy processing • No investment for kiln and refractory furniture • Fulfilment of particle size requirements • Many impurities from grinding media • Low productivity (low bulk density powders) • Difficult control of particle size distribution Hydrotermal • Easy processing • No investments for kind and refractory furniture • Fulfilment of particle size requirements • More expensive raw materials • Time consuming commplex treatments• Large amount of fluid effluents • Need of consistent plant investment Figure 53.
