Abstract

Hot water boiler contains a rectangular panels and tubes, connected by a water bypass pipe so that they form a radiation and convective heating surfaces, which are in prismatic flue boiler. Prismatic vertical flues enclosed rectangular pipe and round pipe convection heating surfaces without the use of collectors connected inside the duct with rectangular vertical pipe and form a coil bundles of tubes with a corridor or chess. Each individual coil bundles lower end attach to the bottom of a vertical rectangular tube, and the upper end to the upper part of the same vertical pipe so that the pipe with a rectangular coil circuit forms a natural circulation. Outside prismatic flues edged sheet metal, vertical rectangular tubes, located on opposite sides of the prismatic combustion chamber or flue made to shift at least one step, so to rectangular pipes on one side duct on opposite its side located recess formed adjacent pipes and the outer metal rim. Niches are used for fixing the coil convection heating surface of vertical and horizontal displacement.
