High pressure heater is introduced from the high pressure steam turbine to heat extracted high pressure boiler feed water, low pressure heaters are introduced to the low pressure steam from the turbine is heated by the condensation of low-pressure feed water pump,so that the water reaches the desired temperature,in order to improve Turbine flow characteristics, thus ensuring the output and improve cycle thermal efficiency of the plant unit.
Heat transfer effect
The use of advanced design methods, choose the best soda velocity, heat transfer, small steam resistance.
Structure
According to user requirements, design set along vertical and horizontal U-tube vertical U-tube and other types of heater coil. Unique coil heater structure, with good heat transfer, easy to replace the coil and so on. Heat transfer tubes according to user requirements, design of steel and stainless steel tube. Protection system
Each (sets)are designed with reliable security protection systems, each with water heater are displayed, regulation and alarm devices,automatically adjust the water level of hydrophobic, can go quickly bypass the accident, the tube side and shell side are installed there is a safety valve to prevent overpressure.
Small thermal stress
Overheating countercurrent heat, which reduces the tube sheet thermal stress, but also eliminates the stress corrosion pipe and tube plate junction.
Heat transfer area large margin
Under the same parameters, the ratio of domestic and foreign trade company designed heat transfer area of the heater left some large marain(about 5-10%), to ensure a good adaptability to different conditions in the water temperature rise. Anti-red device
In the design, the inner tube to limit water flow rate less than 2.4m /s,feedwater inlet side of anti-red means, to prevent erosion of the inlet end of the tube, the steam inlet of the installation of the baffle within the tube bundle steam flow rate limit, in order to cushion the impact of the heat transfer tube.
Reliable strength
On the basis of the pressure tube sheet design analysis, tube sheet pressure distribution is reasonable,even by force piping, the heater get high reliability in operating conditions.
Tube sheet welding
Automatic welder welding, thus ensuring the carbon content of the surfacing layer and welding quality tube and tube sheet Tube sheet drilling
CNC drilling drilling tube plate processing. to ensure the accuracy of holes, geometric tolerances and surface roughness.
Tube and tube plate Expansion
Expanding the use of machine Expansion, Expansion length can reach the entire tube sheet thickness, high efficiency and stable expansion quality ensure the bonding strength of the tube and tube sheet.
Tube and tube sheet welding
Using automatic welding, welding and two times over since the filler wire welding, fillet height ≥3mm, conduct testing and inspection to ensure weld quality.
Access to water,the tube plate,water-side cylinder, cover
Access to water, the tube plate, water-side cylinder, cover all grade 3 or 4 grade forgings, tube, cap sealing surface roughness of machining tools or abrasive than 3.2um, this sealing surface at various power plants in operation without a leak.
Tube plate case
After processing the tube plate were placed in clean oil tank corrosion,rust cleaning, after cleaning the tube plate and pipe welding quarantees the expansion quality.
