<p>The arrangement for automatic pressure monitoring is used for monitoring firing plants, using gas or liq. fuel, for hermeticity. A continuously operating monitor detects leakage and concentration of dangerous substances in the boiler firing plant during plant operation. Samples are drawn from combustion chamber (5) of a heat generator by a pump (1) through pipes (2). The measuring sensor (3) acts in conjunction with an electronic analyser which releases warning signals when dangerous concentrations are reached and the plant may be shut down. The leakage is detected by concentration measurement e.g. by the properties of the volumes of unburnt gases and volumes of air.</p> |
