<p>PURPOSE:To keep stabilized gas atmosphere by providing a gas monitor which has a function to set the gas concentration arbitrarily, and is equipped with a contact to operate at the set concentration and another contact to operate at the concentration arbitrarily higher or lower than the set one. CONSTITUTION:The system is provided with a combustion furnace 12 for combusting carbon-containing fuel, a blower 14 for cycling the air, and adsorption unit 22 and 23 containing adsorbent to adsorb excessive carbon dioxide. A gas monitor 45 is provided with sequential controller 50 which allows various parts to operate based on the detection of the gas atmosphere in duct switching valves 28, 29, 33, 38, 41, 42, 49 and the storehouse 1, and has a function to set the gas concentration at an arbitrary level, a contact 48 operating at a prescribed gas concentration and another contacts 51 and 52 operating at a concentration arbitrarily higher or lower than the prescribed one.</p> |
