Heating water boiler «Kolvi 120»
Description
The KOLVI 120 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, as well as two pipes for safety valves. A drainage connection with an external thread is located in the lower part of the body. The casing is made of carbon steel and consists of two shells connected by a pipe board in the front part. Between the shells are seamless steel convection bundle flue pipes, and the inner shell forms a dead-end furnace chamber. The flue gases pass through the flue tubes with turbulizers to the flue gas box and are discharged through the chimney. The hinged furnace door is protected by heat-resistant concrete and equipped with a viewing window.
The boiler operates on natural gas or liquid fuel (fuel oil, diesel fuel), depending on the burner. The high efficiency (up to 93%) is ensured by a multi-pipe flue and optimized water circulation. The automation system guarantees stable operation and safety. The boiler is used in stationary and transportable boiler houses for heating residential, administrative and industrial facilities in closed heating systems.
