Heating water boiler «Kolvi 270»

Description

The KOLVI 270 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 cladding. 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 hand, each shell has a welded bottom with a gap between them. 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 and is equipped with a viewing window, and has a groove for a sealing cord around the perimeter.

The boiler can operate on natural gas or liquid fuel (fuel oil, diesel fuel), depending on the burner. The high efficiency (up to 92%) 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.
