Abstract
Description
Claims (12)
- A condenser, comprising a steam inlet and an exhaust chamber which are connected with each other via a plurality of cooling tubes connected in parallel, which exhaust chamber is provided with an exhaust opening which is connected to a pump for discharging inert gas, wherein the condenser is provided with a supplemental barrier to screen the pump during use from steam breaking through a cooling tube.
- A condenser according to claim 1, wherein the supplemental barrier is designed as a flow resistance.
- A condenser according to claim 1 or 2, wherein the supplemental barrier is placed upstream of the pump and, while leaving clear at least one suction route from steam inlet to pump, at least partly closes off at least one other suction route from steam inlet to pump.
- A condenser according to claim 2 or 3, wherein the flow resistance comprises a restrictor.
- A condenser according to claim 2 or 3, wherein the flow resistance comprises a variable valve.
- A condenser according to claim 5, wherein the flow resistance comprises a thermal valve which hampers the throughflow when a predetermined temperature of the passing medium is exceeded.
- A condenser according to any one of the preceding claims, wherein the cooling tubes are divided into groups and terminate per group in a separate exhaust chamber.
- A condenser according to claim 7, wherein the exhaust chambers are each provided with their own pump.
- A condenser according to claim 7, wherein several exhaust chambers are connected with the same pump.
- A condenser according to claim 9, wherein between each exhaust chamber and pump, a separate exhaust line is present in which a flow resistance is included for screening the pump from steam breaking through.
- A method for condensing steam in a cooler, wherein by means of a pump, through discharge of inert gas, a low pressure is maintained in the cooler, and wherein the pump is screened from steam breaking through the cooler.
- A method according to claim 11, wherein the pump is screened in that, upon steam breakthrough, while leaving clear at least one suction route between steam inlet and pump, at least one other suction route between steam inlet and pump is closed off.
