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.
In practice, the rate of heat transmission per square foot of heating surface varies from 800 B. T. U. per hour and upwards, in cast-iron sectional boilers for domestic heating, to 15,000 B. T. U. per hour in the high-pressure water-tube boilers used in torpedo boats.. The actual heating surface of a boiler includes all parts which have water on one side of the metal, and gas having a higher
Aug 17, 2018· heating surface (plural heating surfaces) In a steam boiler, the aggregate surface exposed to fire or to the heated products of combustion, especially of all the plates or sheets that are exposed to water on their opposite surfaces. Synonyms . fire surface; Translations

File Size: 139KB 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
Jul 15, 2019· To calculate the boiler heating surface required; Boiler horsepower is used rating a boiler's capacity to deliver steam to a steam engine. The amount of energy needed to produce 34.5 pounds of steam, per hour, at a pressure and temperature of 0 Psig and 212 deg.F, with feed water at 0 …
Boiler Compoments Manufacturers in India · Power Plant Chhattisgarh Boiler · Contact Us Boiler Capacity Calculation with Heating Surface Area 2018-09-29 11:00:44. 1 ton steam boilers generate 600,000 calories of heat, according to the standard per square meter of building (residential, office, hotel, etc.) heating 100 calories, so a ton of steam boiler standard heating area of 600000 /100 = …
The example also shows that you can have comparable performance even when the the total surface area varies by 9% (for each boiler, total area = sum of furnace, evaporator, economizer areas, which total 13,158 vs. 14,336 sq. ft) Also, the location of the convective superheater affects the surface area significantly. The company where I am
Jun 03, 2018· Assume boiler with dimensions 10 x 10 x 20 surface is 10 x 10 x 2 = 200 and 10 x 20 x 4 = 800 total 1000 SM volume is 10 x 10 x 20 = 2000 M^3
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
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
The heating surface of a boiler is all the surfaces that have boiler water on one side and hot gases of combustion on the other. The surface in contact with the water is the surface that is measured.
