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.
The hot water supply boiler(s) shall be an A. O. Smith Genesis Model GW _____ having an input rating of _____ BTU/hr,and an output rating of _____ Btu/hr when ﬁred with (Natural/Propane) _____ gas. The boiler shall bear the ASME “H”stamp and shall be National Board registered (CRN in Canada) for 160 PSI working pressure.
Boiler Short Cycling Short Cycling. Boiler short cycling occurs when a boiler subject to its own internal thermostat 'fires up' - starts operating when the thermostat detects that the water in the boiler has cooled down.. For example: When your heating system does not require the boiler to fire, the heated water in the boiler's heat exchanger will begin to loose heat to the air around the
A boiler cycle consists of a firing interval, a post-purge, an idle period, a pre-purge, and a return to firing. Boiler efficiency is the useful heat provided by the boiler divided by the energy input (useful heat plus losses) over the cycle duration. This efficiency decreases when short cycling occurs or …
Author: steven lavimoniere Jun 01, 2017· 4 Ways to Maximize Your Steam Boiler’s Cycles of Concentration Improve your steam heating return on investment by optimizing the cycles of concentration, enabling a higher condensate return. Other strategies include producing higher quality makeup water and implementing remote continuous operation and monitoring.
User rating: 4.8/5 Jul 21, 2019· Proper hot water boiler sizing Efficient boiler operation is all about run times. The shorter the cycle the less efficient the boiler becomes as standby losses increase. We don’t want to heat the system water too quickly. Smaller inputs and slower temperature changes are key to greater comfort and higher efficiencies.
The solution in most cases is to modify the boiler and/or feedwater system to prevent the sudden entry of cold water into hot boiler components. When a boiler is experiencing cracking due to subcooling and cold feedwater flow upon startup, one solution is to install an offline pump-assisted circulation system to reduce the thermal transients.
Jun 08, 2009· This is a separate insulated water tank that is heated using hot water from the gas- or oil-fired boiler. The indirect tank is usually plumbed to be a separate "zone" on the heating system. One advantage of this option is that during the warmer months the boiler only has to fire up occasionally to heat water in the indirect tank.
Author: Taylor Industrial Author: Bob Formisano Mar 15, 2013· By comparison, hot water heating (hydronic) systems exchange heat from the water to the living space the moment the pump turns on. Same can be said for the fan and burners of a hot air system, the difference being the steam and hydronic systems release heat long after the whole process shut down because the radiators are still hot and release
File Size: 108KB Jan 01, 2019· The 83 is the boiler manual stated water flow temperature when set to hi. This water is then pumped thro a local unvented hot water tank heating coil. The tank has a thermostat which appears to match the actual tap outlet water temperature.
Adding water chemicals to your system can help to keep the corrosion down, and boiler blowdown will make sure that silting and other solids produced by the chemicals are released harmlessly. Excessive pressure can also cause wear-and-tear on your boiler, and you may find that over use of the boiler will also damage the hot water system to the
Boilers that are designed to provide heating and hot water are either: Tankless coil systems. Indirect systems. Tankless coil systems use the boiler’s heat exchanger to heat water on demand. That means, any time you turn on a hot water faucet, water will run over …
