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.
Types of Pulp and Paper Boilers. With more than 25 years of experience in the pulp & paper industry, National Boiler Service has the expertise to maximize the lifespan of your boiler system. We specialize in modernizing pulp and paper boiler systems to meet changing government regulations, such as the Boiler MACT rule. Biomass Boilers
Paper Mill Boiler Chemical Cleaning – Why, When and How Executive Summary A pulp and paper mill's operation requires that its boilers operate reliably and efficiently. Excess deposits within boiler tubes can cause failures of the tubes, which not only result in lost production, but can also
In the highly-competitive pulp and paper industry, top performers have discovered ways to increase machine reliability and uptime while minimizing costs. For decades, Control Associates’ and Emerson’s process automation and controls experts have guided mills down the path to operational excellence, reducing process variability, energy and
Calculator – Weight Per Foot The ASTM calculation assumes that the tube is manufactured with a consistent wall thickness. The actual wall is always thicker than the specified minimum.
In a boiler this size (10-inch diameter by 41-inch length) I usually use 5/16" plate. I use only PVQ plate. Sa285 GrC is getting harder to find these days. SA516 Gr70 is much easier to get. Boiler plate used be sold as firebox quality or flange quality. Those terms fell into disuse in the early 70's, about the time I started building boilers.
Jun 08, 2017· Remeha sets new standard for boiler size and weight. 08 June, 2017. A single-piece cast-aluminium heat exchanger is the key to the small size and weight of Remeha’s Gas 220 Ace boiler. Thank you for registering for a copy of Modern Building Services.
6 Design of an industrial boiler 7 How an industrial boiler system works 8 The use of boiler systems in practice such as the paper, building, chemical or textile industry, many processes function only with heat (process heat). which corresponds to the weight of 120 VW Golfs. Hot water or steam boilers are relatively similar in design
The white paper discusses factors that contribute to a good boiler chemical cleaning program, including: How deposits and their thicknesses, densities and compositions affect boiler reliability and efficiency. The steps required to plan and execute a boiler chemical cleaning program.
Boilers, were a major part of the Industrial Revolution beginning about 1700. They are major consumers of industry and building energy consumption today. Industry: boilers are used for power generation, process heat (e.g., refineries, petrochemicals, paper mills, tire manufacturing, etc.) and heating.
