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.
Advantages. Lower heating costs — Biomass systems typically cost less to operate than other systems.Click here to compare operating costs of different heating systems.; Convenient, whole-house, renewable heat — Whole-house pellet boilers are more convenient than typical pellet and wood stoves. They are controlled by a thermostat and pellets are automatically fed into the boiler.
An introduction to biomass boilers. Biomass boilers are a low-carbon and renewable energy source which burn biological plant material – predominantly wood – in order to generate heat or both heat & electricity for combined units.Biomass can be used to heat spaces and water for homes, businesses and communities and can replace existing coal, gas or oil boilers.
Efficiency. Biomass boilers are very efficient as they have been built using the best of modern technology. They will currently operate at 90% efficiency which is a huge amount more than with conventional boilers and electric heating systems.
Boiler Efficiency Improvement Steps: After Analyzing heat losses in industrial boilers, boiler engineers or technicians can help you to increase your boiler efficiency by 6% – 10%.. Here are the few boiler efficiencies boosting steps listed below:. Complete combustion of fuel so that no unburnt is left behind is a good practice and will add to the boiler efficiency.
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.
Report on conversion efficiency of biomass This calculation is used mostly to obtain the potential efficiency of boilers units. However, in practice boiler efficiency is directly affected by a wide range of both internal and external factors (e.g. climate, scale, moisture
File Size: 1MB This Efficiency Facts Booklet is designed to clearly define boiler efficiency. It will also give you the background in efficiency needed to ask the key questions when evaluating efficiency data, and provide you with the tools necessary to accurately compare fuel usage of …
Mar 02, 2015· Biomass boiler efficiency in general has come under some criticism in a recent Guardian article .. Key points from the Guardian article are that a DECC study of installed biomass systems found that the average efficiency of the boilers was 66.5%, that the surveyed systems can only reach 76% efficiency, and that this is lower than the needed 85% efficiency to contribute to carbon targets.
Biomass boilers require on-going maintenance in order for them to function efficiently. Although ash quantities are usually low, biomass boilers and stoves will still need to be swept on a regular basis to remove the ash and keep them clean. The ash bin will need to be emptied about once a week.
Biomass needs to be made dense to provide ease of mechanical handling and feeding, uniform combustion in boilers, reduced cost of transportation and ease of storage. The types of dense biomass to choose from are pellets, briquettes or loose biomass that has been dried before being fed into the boiler.
File Size: 296KB Biomass boilers could benefit from the Renewable Heat Incentive (RHI) which may recoup some of the installation costs.. According to the Energy Saving Trust, an automatically fed pellet boiler costs between £9,000 and £21,000, including installation.Because of significant differences in price it can be difficult to weigh up the competing claims of different suppliers and products.
