Pit heating
Requirements:
- Modernization of an existing pit heating
- At a depth of 60 meters, a minimum temperature of 8 ° C is desired
- Use of three heat generators, which are used in cascade, to realize the heat capacity
nordluft's solution:
Usage of three warm air heater with a heat capacity of 860 kW each. The combustion chamber is made of chromium-alloyed, high heat-resistant stainless steel. The shell-and-tube heat exchanger, also made of alloyed stainless steel, is equipped with flue gas turbulators and a condensate drain.
Technical data for each device:
- Rated air flow: 43.000 m³/h
- Warm air capacity: 50.800 m³/h
- Heat capacity: 860 kW
- Temperature increase: 50 K
