WELLONS.RU LLC is a manufacturer of boiler equipment with a high unit thermal capacity (up to 280 MW, high pressure steam), a representative of the American company Wellons USA in Russia. In the projects, both in North America and in Russia, we traditionally use monolithic plastic refractory for lining the working layer of high-temperature boiler furnaces. It is important for us that this refractory, in addition to the basic properties of refractoriness, wear resistance, is completely ready for use, i.e. did not require preparatory work, formwork devices (in most cases). This can significantly reduce the lining time and does not require the involvement of highly qualified personnel.
