It is known for a long time that "classic" heating systems in which boiler rooms and water radiators are used are ineffective for production facilities of large area especially if they have considerable height (usually more than 5–6 meters). It is purposeful to switch to direct-gain systems (infrared heating) for heating factory and industrial workshops of considerable height in conditions of modern technology development.
Works on designing, procurement, installation and commissioning of the decentralized heating energy-saving system using Robert Gordons (USA) gas IR burners were executed in the scope of implementation of the project at the first aisle of Storehouse No. 7, Production Department No. 60, Izhorskie Zavody OJSC. The IR Heating System allowed providing surface temperature at the storehouse not lower than +5 °C. At that the existing system of centralized water heating of the specified aisle should be disconnected and not used.
The heating system based on gas infrared burners is the most economically advantageous as it allows performing zoned heating and reducing heating costs as a whole. In addition infrared heating burners only allow achieving preset temperatures in the existing shop features: large height and therefore volume, enclosing structures with low heat-protective properties, large area of glazing, outer gates without heat insulation etc.
16 infrared gas radiators are used to maintain indoor temperature not lower than +5 °С at the entire area at outside air temperature down to -26 °С.
All instruments are mounted on walls in the room and connected to unified automatic zoned temperature control system. Therefore they are switched on for a time at temperature decrease below required value.
The heating system of total power 800 kW and with heated area 2592 km2 at building height 20 m was created.
