Abstract:
The invention relates to a device for treating water of the spray type, such as a deaerator or preheater. According to the invention the connection between the vessel (12) and the sprayer (34) and the supply of water to be treated comprises a pipe section (40) having a first open end in fluid communication with a treatment chamber and a second open end provided with a first flange (60) for connecting to a sprayer (34), the sprayer (34) comprising a sprayer flange (68) connected to said first flange (60), the sprayer flange (68) carrying the sprayer (34), which is in fluid communication with a connecting pipe (72) at one end thereof, the connecting pipe (72) extending through the first flange (60) to a coupling flange (74) for connection to the supply of water to be treated.
Abstract:
The invention relates to a heat recovery unit (10) for generating a heated fluid by a hot exhaust gas, comprising: a housing (12) having an inlet (14) for introducing hot exhaust gas and an outlet () for discharging treated exhaust gas, and arranged in said housing (12) at least one heat exchanger (20) for heat exchange between the hot exhaust gas and a fluid, and an auxiliary combustor (22) for combusting fuel with hot exhaust gas, the auxiliary combustor (22) being provided with a fuel supply (24; 82), which auxiliary combustor (22) is arranged downstream of the at least one heat exchanger (20) in said housing, wherein an exhaust gas bypass (26; 27) for a part of the hot exhaust gas is provided, having an inlet (108) for exhaust gas, and being positioned upstream of the at least one heat exchanger (20), and having an outlet (113) in fluid communication with the auxiliary combustor (22).
Abstract:
A device for degassing water and separating a steam/water mixture into steam and water comprises a vessel (41) having at least one sprayer (4), which is arranged in the top of the vessel, for feeding water which is to be degassed, at least one outlet (6) for gases which have been separated off, a manifold (7) which is arranged in the vessel and has a feed connection (47) for steam, and at least one outlet (11,12) for degassed water. The device furthermore comprises a separating device (2) for separating water and steam. The water which is to be degassed is sprayed, by means of the sprayer (4), as droplets (29) into the vessel, which is also partially filled with at least partially degassed water (30). Via the manifold (7), steam emanating from the separating device (2) is passed through this water. The steam is discharged from the vessel together with gases which have been released from the water and with gases which have been released from the water sprayed by the sprayer, and the degassed water is drained off. The water which has been separated off in the separating device is added to the degassed water in the vessel. That part of the steam separated off in the separating device which is not used for degassing purposes is used as process steam.
