Product DescriptionVenturi steam pipelineThe desuperheating atomization system adopts the Venturi tube, which is the most widely used and most frequently used in China, in combination with various nozzles to meet the requirements of various complex working conditions. This system features low noise, no transmission components, durability and no jamming. Its characteristics are as follows:1.The Venturi tube design takes into account that when the steam load is low, the steam flow rate slows down. No matter what kind of nozzle is used, the atomization effect is not ideal, and the steam carries water. Therefore, our company adopts Venturi tube auxiliary atomization, which greatly increases the flow rate of steam, ensuring that the desuperheating water and steam can be fully atomized. The desuperheating effect is excellent under various complex working conditions.2. A protective inner lining is added inside the mixing tube to prevent thermal shock, protect the outer tube and extend the service life of the equipment. If no protective pipe is added, the steam will come into direct contact with the inner wall of the pipe. The temperature and pressure inside and outside the steam pipe will differ greatly. Under the alternating cold and hot conditions, it is easy to cause metal fatigue, form network cracks, and even cause the outer pipe to bulge, resulting in safety accidents. The protective liner is designed and installed in the mixed pipe section. The protective liner is a non-pressure-bearing component and has been fully preheated. The temperature and pressure inside and outside are balanced. When the desuperheating system malfunctions, it greatly reduces the impact of desuperheating water spraying on the protective liner and avoids accidents.3. According to the working conditions, the insertable multi-nozzle assembly (see the figure below for details) is selected for design, which ensures stable and reliable atomization and facilitates the disassembly, assembly and maintenance of the nozzles.SpecificationThe unique design generates high velocity and turbulence to mix cooling fluid and steam,achieving ultrasonic atomization for effective desuperheating.Cooling water enters a preheating chamber surrounding the internal Venturi tube and is injected through small holes, facilitating final atomization by superheated steam passing through the throat. The mist then contacts the main steam flow, ensuring minimal pipe wall erosion and optimal efficiency.Key Features:1.Turndown ratio up to 20:1;2.Cooling fluid atomization allows downstreamtemperature to approach steam saturation temperature;3.No moving parts, reducing wear and maintenance;4.All-stainless-steel internals;5.Relatively low pressure drop;6.Feedwater pressure exceeds steam pressure by 0.1~0.2MPa.Physical photo 1Physical photo 2Physical photo 3 Dimensional SpecificationsSizeABCDEFWeight(kg)DN505015755025030018DN8080151255030035023DN100100151507035042535DN1501502017812753366068DN20020020225150650800125DN250250202502008001000180DN3003002525020010501250320DN3503504030022513001525390DN4004004030025016001850500DN4504505035030019752275DN5005005037535022502600Basic ordering requirementsFor customized desuperheating and pressure-reducing devices or valves, please provide the corresponding data as presented in the table below.Device modelDevice nameQuantity (sets)Inlet steam flow rate Q(t/h)Range of changeImported steam pressure P1(MPa)Range of changeImported steam temperature T1(℃)Range of changeRated outlet steam pressure P2(MPa)Deviation rangeRated outlet steam temperature T2(℃)Deviation rangePressure of deheated water Pb(MPa)Range of changeTemperature of deheated water Tb(℃)Range of changeNoise(dBA)The layout method and structural form of the device1,Horizontal 2,VerticalDimensions of imported pipelinesFlangeDimensions of the outlet pipelineFlangeThe size of the desuperheating water pipeWeldingWeldingControl modeThe required documentsOthers1,Electric control 2,Pneumatic control 3,Hydraulic controlenforce standardsSpecial requirementsAfter Sales ServiceWarranty period: Within 12 months from the date of equipment acceptance and normal use, or 18 months from the date of arrival, whichever comes firstTraining: Remote operation/maintenance trainingAfter-sales service commitment: Lifetime provision of spare parts and maintenance services.
