WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
1. Digitized manufacture
The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
The front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful.
2.Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
3. Longer working life
Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boilers working life.
Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will have 100% radiographic inspection.
Fin tube us ND steel or stainless-steel material which avoid low temperature corrosion.
Inspection procedure point is set up to guarantee the sequence of expanding and welding, avoid cracking of the tube sheet holes.
4. Less fuel consumption
High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ to control heat lost.
Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power.
Condenser is added to reuse the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce emission temperature, which can increase the thermal efficiency above 98% and save operating cost.
The vacuum deaerator adopt wooden cases package:Generally, use pine and multilayer composite board will be adopted for export;the positions or standard forklift and fork arm have been left at the bottom;the length,width and height are set in accordance with the specifications and dimensions of the vacuum deaerator;adopt bolt,nut,gasket and
User rating: 5/5 Deaerator Data Sheet. Internal design pressure shall be a minimum of 30 psig. Design temperature shall be a minimum of 400 ºF. The vessels shall be designed for full vacuum. The materials used for pressure parts and for external supports shall be in accordance with the ASME Code, as necessitated by the design pressure and temperature. The
The deaerator specification is the most important tool available to improve the construction full vacuum to eliminate vacuum breakers, which allow oxygen to be drawn into vessels during sw and (g) high oxygen in the boiler feedwater from the deaerator. Conclusion
Model SP Deaerator. Specification. Furnish and install as one Deaerating Heater as designed and manufactured by Precision Boilers. Deaerator shall be model number _____ and shall consist of the following: (1) Basic: _____PPH Spray/Scrubber Type Deaerator with a capacity of _____ gallons to overflow (_____ minutes of storage). Storage vessel
A typical vacuum deaerator is shown in Figure 10-7. Important Considerations Inlet water to the deaerators should be largely free from suspended solids, which can clog spray valves and ports of the inlet distributor and the deaerator trays.
Since the reinstatement of the deaerator section Kansas City Deaerator was instrumental in writing a majority of the current HEI specification for deaerators over the last 30 years. ABMA: Kansas City Deaerator is a past member of the American Boiler Manufactures Association.
Vacuum deaerators are used where there is no possibility to heat the water to 102-104°C due to the absence of steam. Therefore vacuum deaerators are used for the district heating boilers and hot water systems. Principle of operation. water is heated to a temperature to 60-70°C using a plate heat exchanger, and then enters the top of deaerator.
The deaerator system should be designed to maintain a constant operating pressure and temperature within the deaerator through all operating ranges. Several design suggestions should be considered. First, install a pressure-reducing valve in the steam line that feeds the deaerator, with its sensing line inside the deaerator itself.
A vacuum deaerator is used for treatment of circulating water in heating plants. The circulating water should not contain oxygen as this increases the risk of corrosion on the system. The oxygen is dissolved in the make-up water and thereby enters the tank together with the make-up water, which normally contains 6-8 mg/l oxygen.
