Abstract
The invention discloses a heat accumulating type pure air heating system with the constant outlet temperature. The heat accumulating type pure air heating system comprises a heat accumulator, a burner and a pipeline heat exchanger. The heat accumulator is horizontally arranged, and a ceramic honeycomb body is mounted in the heat accumulator. The burner is mounted at the front end of the heat accumulator and connected with the heat accumulator through a flange. The pipeline heat exchanger is mounted at the rear end of the heat accumulator and connected with the heat accumulator through a flange. After heat accumulation is completed by the heat accumulator, normal-temperature high-pressure air is introduced through the front end of the heat accumulator, passes through the heat accumulator and then enters the pipeline heat exchanger, the temperature of the outlet high-pressure air is controlled to be the specified temperature by adjusting the water flow entering the pipeline heat exchanger at the moment, and the cooling water flow is gradually reduced along with time, so that the exhausted high-pressure air outlet temperature is kept constant as the specified temperature. The heat accumulating type pure air heating system is suitable for ground test systems needing high-temperature high-pressure pure air and can provide the high-temperature high-pressure pure air with the constant temperature for a long time.
