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.
File Size: 296KB Boiler efficiency measures the relationship between the energy input and energy output of a boiler system. This ratio is expressed as a percentage and is used to assess the performance of the boiler and the burner as a means to determine the fuel costs of your boiler equipment investment.
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.
RE: Calculating the Energy savings of reducing steam boiler pressure davefitz (Mechanical) 23 Jan 18 14:57 Theoretically the main energy savings ( in steady state) could occur by eliminating the frictional losses assocated with pressure drop thru the valves, ie, operate with all valves wide open.
File Size: 416KB When calculating the return on energy efficiency investments, consider the value of increased occupant comfort in energy-efficient buildings in addition to the financial savings. For example, natural lighting and better indoor air quality in schools can lead to reduced absenteeism among students and faculty, and better student performance.
combustion. The result is energy loss as the vapor absorbs energy in the boiler and lowers the efficiency of the equipment. The specification used to calculate efficiency must be based on the fuel to be used at the installation. As a rule, typical natural gas has a hydrogen/-carbon (H/C) ratio of 0.31. If an

But, what would that cost you? Presumably, someone came up with that pressure to achieve some sort of design requirement. Blithely assuming thatSavings should primarily be from reduction of system losses. Calculate the piping and boiler shell losses at both temperatures.The Cleaver Brooks 4WI boiler book ( which is on the net ) has a worked example which should help you with this estimate - see pages 11-13. WorkingThank you. I will check out that reference. Regarding what it will cost, I've looked into that I ready. This is a hospital that was served from anoReducing the exit gas temperature by 9 degrees will "probably" not be enough to cause condensation of acidic gases in the exhaust, but in other casWhy not run the boiler at 85 psig, maximize cost savings, and eliminate one level of pressure reduction controls? Or, is pressure control deemed tIt's a hospital that needs 85 going to the sterilizers.. the powers-that-be are nervous enough about the possibility of reducing to 125. No logicThere may be more fertile ground for energy savings with the low grade heat from the stack exhaust than with steam pressure reduction. Examples wouGiven that this boiler operates at 83% eff at design load, suspect you'd be struggling to get a decent power extraction or chilling duty stream froEnergy savings would correspond to energy losses, since these are directly proportional to dT, you can just take the dT at on pressure and divide i Boiler Efficiency Calculators Boilers and steam systems consume large amounts of energy and may present an opportunity for significant cost savings.

File Size: 1MB Aug 21, 2017· Calculate Your Cost Savings with an Energy Efficient Boiler Modern technology has transformed commercial boilers , allowing companies to save between 20%-50% in energy costs . In December of 2016, the U.S. Department of Energy released a new energy efficiency standard for boilers.
File Size: 881KB Boiler efficiency, in the simplest terms, represents the difference between the energy input and energy output. A typical boiler will consume many times the initial capital expense in fuel usage annually. Consequently, a difference of just a few percentage points in boiler efficiency between units can translate into substantial savings.
