For more than 15 years, Alfran has been supplying and installing a wide range of monolithic vibrocoated and projected refractories (Gun, High Gun and shotcrete Alfranjet) in coal-fired power plants. Likewise, it has carried out several desulfurization projects in their respective chimneys with supply and installation of different concretes from the Alfranjet range. The works include the demolition of the coatings in poor condition, welding of anchors and installation via shotcreting. The use of the technology shotcreting, with the machines of high pressesure and speed of pumping, makes possible the installation of more than 80 tonnes per day to heights superiors to the 100 m, which reduces considerably the times of installation, improving the conditions to the low rejection and little dust, at the same time as it allows simultaneous mechanical works in the same areas of the boiler. In the different boiler maintenance and chimney revamping shutdowns in which Alfran has participated since 2000 in Spain, we have supplied more than 6,700 metric tons.
