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.
Jan 16, 2007· the calculation goes like this, diam x pi x length of tube in inches x number of tubes divided by 144 so question,, what is the heating surface area of a boiler with 21 tubes, 2.5" in diam, 16' long. the calculation will look like this.
May 05, 2017· Homework Statement A boiler drum is equipped with hemispherical heads (i.e. the two heads together make a sphere.) The diameter of the drum is 0.8 meters and the drum is 5 meters in length. Calculate: a.) The area of insulation required to cover the entire drum. b.) The total
Reg. 383 Measurement of heating surface. a) For the purpose of regulating the area of the safety valves and the amount of registration and inspection fees the “heating surface” of a boiler shall be the total surface of all plates and tubes exposed to heat on one side and in contact with water on the other measured on the water side or the
What is a BTU? The British Thermal Unit, or BTU, is an energy unit. It is approximately the energy needed to heat one pound of water by 1 degree Fahrenheit. 1 BTU = 1,055 joules, 252 calories, 0.293 watt-hour or the energy released by burning one match. 1 watt is approximately 3.412 BTU per hour.
The conclusion is: Simply deciding on a particular boiler design or supplier simply because the design has more surface area can be wrong. Unless one can perform heat transfer calculations and check the surface area of each boiler, one should stay away from comparing surface areas. I stress this because with easy access to spreadsheets, even
2004-12-10 · Determining Boiler Capacity from Heating Surface Area but I need to convert this area into boiler rate is 3 1/2 lbs saturated steam per sq.ft of heating afbc boiler heat transfer area calculation.
In fire tube boilers, normally the heat transfer area of reference is taken as the outside surface of the tubes. So you use the outside diameter of the tubes for the calculation of the heat
Keyword: CFBC Boiler Manufacturer, boiler heating surface area calculation FAQ about boiler heating surface area calculation 1.Why choose ZG as boiler heating surface area calculation manufacturer? We have over 70 years' experience of industrial steam boiler and autoclave,and we have a professional installation and after-sales staff for products.Take advantage of the most economical way to
About Us · Products Dec 10, 2004· RE: Determining Boiler Capacity from Heating Surface Area chicopee (Mechanical) 5 Dec 04 19:27 Since Your D-type WT boiler has water-cooled metallic walls,the average heat release in the furnace is 30,000 btu/hr per cu.ft. of furnace volume for continuous operation and 60,000 for peak operation per Kent"Power" 12 th Ed. pg 7-75 table 3.
the boiler. The heating surface area was increased for sake of efficiency and fast steam generation by reversing tube boiler was not prevalent until after the first water-tube .. The thermal design calculation involves the heat transfer from all . Heating surface of a boiler is the area of the tube surface that is exposed to the heat.
hp is calculated by the blr mfr but probably have 400 to 600 hp if you calc 5 sfhs to 8 sfhs per bhp. newer boilers are squeezed to 5 or 6 sfhs/b1Steam generating capacity can be determined from heating surfaces on a FT boilers but w/WT boilers the steaming capacity determination is a littleSpirax Sarco has a module on boiler ratings and boiler horsepower in their website learning centre. Block 3, module 3.5 I think. Not too sophisticaSince Your D-type WT boiler has water-cooled metallic walls,the average heat release in the furnace is 30,000 btu/hr per cu.ft. of furnace volume fRat, How about something really approximate such as comparing outside dimensions to modern D-type boilers ? In my opinion, if I have a "box" with t Heating surface area of a boiler is usually expressed in square … Determining Boiler Capacity from Heating Surface Area … Dec 10, 2004 · Determining Boiler Capacity from Heating Surface Area Determining Boiler Capacity from Heating Surface Area … but I need to convert this area into boiler … Heating surface calculations – SmokStak
