Flame detector cooling air system is to ensure that an important part of flame detector probe long-term security work, often as spare by two sets of cooling fan, pressure gauge, pressure switch, air duct conversion baffle, cooling fan control cabinet and so on, two Shared a control cabinet, fan control cabinet according to the operation condition of cooling air system automatic start-stop control two fan.
For some of the operation condition of the cooling air system requirements is not high, such as external snapshot of flame detector probe, discontinuous operation equipment, such as spare fan cooling air system is not set, only using a single fan.
Can of air cooling are taken directly from the atmosphere, can also be taken from the power plant of blower exports.
