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.
Steam Pressure Reduction: Opportunities and Issues varies directly in proportion to the boiler’s net stack temperature (the difference between the flue gas tem-perature and combustion air temperature). When boiler pressure is lowered, a lower stack temperature results. This, in turn, causes slightly improved combustion efficiency.
A boiler is an appliance designed to heat water and produce energy. The heat is applied to water in an enclosed container before being distributed throughout the system. The major difference between a low-pressure and a high-pressure boiler is the amount of pressure per square inch and pounds per square inch gauge that the boiler produces.
Jan 15, 2019· Heat Transfer In Steam Boiler. A steam boiler is designed to absorb the maximum amount of heat released from the process of combustion. There are three way (Radiation, convection & Conduction) that heat is transfer in the boiler and relative percentage of each heat transfer within system boiler is dependent on the type of steam boiler, fuels and the designed transfer surface.
Based on pressure steam boiler can be classified as high pressure steam boiler and low pressure steam boiler. A high pressure steam boiler is boiler in which steam is generated at pressure exceeding 15 psig and operates hot water boiler above 160 psig or 250o F. Application this type usually is used for utility plants, big industrial plants and
File Size: 428KB For example, if a process of which steam consumption is only 5% of boiler output is turned on rapidly (such as with an on-off valve), the system demand can easily increase by 15% or more until the process reaches a steady state of operation. When a steam valve opens, two problems occur in the boiler. First, steam pressure drops rapidly.
Knowing the Cost of Steam C.Percentage of make-up water or percentage of condensate return Normal condensate returns have a higher Btu content than make-up water. Today’s industrial benchmark for condensate return is 90% if the plant is not injecting steam for the process. D. fi eBflecrienocyi Higher boiler efficiency lowers steam cost
A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
Gauge pressure is pressure in pounds per square inch above atmo-spheric pressure which is 14.7 pounds per square inch absolute. Gauge pressure (psig) plus 14.7 equals absolute pressure. Or, absolute pressure minus 14.7 equals gauge pressure. Pressure/Temperature Relationship (Columns 1, 2 and 3). For every pressure of pure steam there is a
File Size: 1MB Aug 10, 2017· It’s all depends on capacity of power plant as I had knowledge of some power plants is 150MW CFBC boiler 137ksc MS pressure 250MW PF boiler 150ksc is MS pressure 600MW PF boiler(sub critical) 180ksc is MS pressure 660MW Pf boiler super critical 23
Superior Boiler offers both Low Pressure and High Pressure packaged steam boilers. These are ready-to-install systems featuring a perfectly matched powerful and efficient burner/boiler combination ideal for Space Heat and Industrial Process applications.
File Size: 1MB steam boilers, are boilers designed for a maximum allowable operating pressure (MAWP) greater than 15 psig. Section IV of the ASME Code would provide rules for steam boilers with a MAWP of 15 psig or lower. B31.1 Power Piping Code provides rules for most …
