Heating water boiler «Kolvi 500»

Description

The KOLVI 500 boiler is a stationary fire-tube hot-water boiler designed for heating water in water heating systems of buildings and structures with forced circulation. The boiler design is a horizontally arranged cylindrical prefabricated welded structure, including a body with a furnace, a furnace door, a flue gas box, thermal insulation and decorative lining. On the upper part of the body there are flanged supply and return water pipes with flanges and two pipes for mounting safety valves, and in the lower part there is a drainage connection with an external thread. The body is made of carbon steel and consists of two shells connected in the front part by a pipe board, and on the other side, each shell ends with a welded bottom with a gap between them. In the space between the shells, the convection bundle flue pipes are made of seamless steel. 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.
