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.
Optimal flow rate for condensing boiler I have a Vitodens 200 8-32 for a two storey brick 1914 house(of 2700 sqft including basement) heating a combination of about 350 sqft of cast iron radiation on a fat pipe gravity system converted to forced circulation as well as 400 sqft of cast iron radiation piped home-run.

This table shows gas flow capacities of pipes from 1/2” to 8” diameter, based upon a pressure drop of 5% of the initial gas pressure for 100-ft. length of pipe. Turbulent
Vaillant ecoTEC plus 837: DHW flow rate at 35°C rise: 15.2 litre/minute. So the heat required is 15.2/60 x 35 x 4.2 = 37.24kW. The manufacturer states 37kW and the 37 forms part of the product name. Handy rule: multiply the hot water flow rate in litres/minute by the temperature rise in celsius.
File Size: 897KB My boiler generates steam at rate of 2 T/Hr having pressure of 8 Kg/cm2. The pressure of steam reduces to 3.0Kg/cm2 after passing through PRV. This 3.0 Kg/cm2 steam is distributed into entire plant.
3.3.6 Equations F-7a and F-7b may be used in lieu of the F or F c factors specified in Section 3.3.5 of this appendix to calculate a site-specific dry-basis F factor (dscf/mmBtu) or a site-specific F c factor (scf CO 2 /mmBtu), on either a dry or wet basis. At a minimum, the site-specific F or F c factor must be based on 9 samples of the fuel. Fuel samples taken during each run of a RATA are
How much natural gas is required to produce 1 ton of steamJun 12, 2019How much steam is produced with a 4-ton boiler?Mar 22, 2019In which unit is steam, coming out from a boiler, measuredJan 26, 2018How much coal is required to generate 1 TPH of steam inJun 01, 2017See more results Feb 19, 2013· Based on the specs of the loading unit maximum flow may be less than boiler output, even at relatively "high" delta-T. Assume output of 160,000 btu, assume maximum loading unit flow rate of 12 gpm (actual spec on one loading unit is a little less than 12 gpm), assume pump head will allow full 12 gpm with the loading unit: If delta-T=30, this
[Steam Property Calculator] => Specific Enthalpy = 1,202.3 btu/lbm; Steam Energy Flow = Specific Enthalpy * Mass Flow [ Steam Energy Flow = 77,125 = 1,202.3 btu/lbm * 60.8 klb/hr] Step 2: Determine Feedwater Properties and Mass Flow The feedwater flow rate can be calculated from steam mass flow and blowdown rate:
Jul 24, 2017· Typically boilers of much size would have a steam meter that calculates flow. This is typically a sensor measuring the pressure drop across and orifice. If you don’t have that, then you have two options. Option one is mainly for firetube style boi

How many lbs per hour of steam is need to heat 40 gallons per minute flow rate of water from 60 ° F to 180 ° F? Sizing a Boiler Feed Pump Receiver. The receiver tank should be able to hold five minutes worth of condensate for boilers up to 200 BHP and 10 minutes of condensate for boilers over 200 BHP.
Steam Energy Flow = Specific Enthalpy * Mass Flow [ Steam Energy Flow = 103,269 = 1,634.1 btu/lbm * 59.9 klb/hr] Step 2: Determine Feedwater Properties and Mass Flow The feedwater flow rate can be calculated from steam mass flow and blowdown rate: Blowdown …
