Hot water boilers of KVGM-180 type have several advantages in comparison with PTVM boilers. They include: high altitude of the furnace with a lifting flow of water in the screen pipes at two-flow circulation scheme; arrangement of convective packages in the downtaking ducts; ensuring shot-blast cleaning of pipes; installation of two speed fan blowing and exhauster, as well as equipping the boiler with the gas recirculation exhauster.
