Heating water boiler «Kolvi 600»

Description

The KOLVI 600 boiler is a stationary fire-tube hot-water boiler designed for heating water in water heating systems of buildings and structures with forced circulation. It is made as a horizontal cylindrical prefabricated welded structure consisting of a shell with a furnace, a furnace door, a flue gas box, thermal insulation and decorative cladding. On the upper part of the body there are flanged supply and return water pipes with flanges and two pipes for safety valves, and in the lower part there is a drainage connection with an external thread. The body is made of carbon steel and includes two shells connected by a pipe board in the front part, and on the other side, each shell has a welded bottom with a gap. Between the shells are seamless steel convection bundle flue pipes. The inner shell forms a dead-end furnace chamber, where the flue gases from the bottom return to the door, pass through the flue pipes with turbulizers to the flue gas box and are discharged through the chimney. The hinged furnace door is protected by heat-resistant concrete, equipped with a viewing window and has a groove for the sealing cord.

The boiler operates on natural gas or liquid fuel (fuel oil, diesel fuel). The high efficiency (up to 93%) is ensured by a multi-pipe flue and optimized water circulation. The boiler is used in stationary and transportable boiler houses of closed heating systems.
