The device relates to the technique of flame spraying, in particular to a device for spraying ceramic materials. The invention provides a reduction in unit costs for the production of building materials. To do this, as a device for the manufacture of building structures used firebox for burning coal. The coal combustion chamber has a vertical combustion chamber as well as two air-fuel nozzles through which coal dust, primary air and recycled gas is supplied. The use of the furnace for the manufacture of building structures by spraying is based on the fact that the gases of the combustion chamber containing molten particles of ash, sand, are directed to a dense surface. To obtain sufficient strength of building structures by spraying sand, it is necessary to heat the surface of sand particles to a reflow temperature at a particle speed of at least 30–40 m / s.
