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.
Back-pressure Steam Turbine Back-pressure steam turbine – schema. Back-pressure steam turbines or non-condensing turbines are most widely used for process steam applications. Steam is a principle energy source for many industrial processes. The popularity of process steam as an energy source stems from its many advantages, which include:
File Size: 513KB Based on the specified operating pressure, the boiler manufacturers will design the boiler parts and safety valve pressure settings in accordance with the ASME Boiler and Pressure Vessel Code, Section 1, Power Boilers. The boiler shall be specified for the maximum steam temperature required at the superheater outlet for operation of the
Back pressure turbines are available in single stage or multi-stage options. Primarily, this kind of turbine is used as a reducing station between boiler unit and the process steam header. Back pressure turbines are commonly employed in industrial plants where a large quantity of steam is required. Their straight-back pressure nature makes them useful in …
Back Pressure Turbines: a type of steam turbine that is used in connection with industrial processes where there is a need for low or medium pressure steam. The high pressure steam enters the back pressure steam turbine and while the steam expands – part of its thermal energy is converted into mechanical energy. The mechanical…
Steam electric power plant with a back pressure turbine. • Gas turbine power plant with waste heat recovery and a steam generator (boiler). • Combined-cycle gas turbine plus steam turbine plant (steam turbine can be back pressure or condensing type). The bottoming cycle is not very efficient.
Jul 08, 2016· Firstly: A steam based power generation unit is a combination of boiler and turbine. The boiler generates steam using coal, natural gas or other fuels such as biomass, and the super-hot, high pressure steam runs a turbine to generate electricity. This is pretty much most power plants worldwide work to generate the electricity for you and me.
a pressure-reducing valve (PRV)—it reduces steam pressure—but uses the pressure drop to produce highly valued electricity in addition to the low-pressure steam. Shaft power is produced when a nozzle directs jets of high-pressure steam against the blades of the turbine’s rotor.
Jan 15, 2019· Boiler in thermal power plant accumulates the steam and build up a pressure to expend it in turbine and convert thermal energy to mechanical energy. The generator which is connected to turbine converts the mechanical energy into electric energy. Types of boiler . 1. Based on Tube Content. Fire Tube; Water Tube; 2. Base on Operating Pressure
several pressure casings and complex design types that maximize the efficiency of the steam thermal cycle in the power plant. In industrial process applications, steam turbines are generally smaller and operate at a lower steam pressure; therefore, the design is …
File Size: 429KB Back Pressure Steam Turbine is also called as Non Condensing Steam Turbine is mostly used in process steam industries or co-generation plants. The non-condensing steam turbine uses high-pressure steam for the rotation of blades. This steam then le
Figure 4 shows the efficiency, η t-s plotted against the pressure ratio, PR obtained for the LPT and compared with that of a commercial low speed turbine which was tested at Imperial College by Szymko .The figure clearly shows that the LPT operates at very low pressure ratios - 1.07 to 1.3 - and that, for the range of speeds tested, all the efficiencies fall between 0.75 and 1.07 of
