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.
BBS three-pass hot water boilers are exceptional due to their high level of efficiency, safety, robust design and minimal operating requirements. That is why they are used in many industrial sectors. Our projects: BBS GmbH delivered an electric steam boiler …
The layout of the tubes involves the number of passes the tube will make to pass the heat from the boiler furnace before being discharged. These can be two- pass and three pass boiler. Depending upon the layout of tubes boilers can be two pass or three pass boilers. Two pass boilers: In two pass the combustion gases travels two times in the boiler.
Construction of three pass packaged type boiler : The packaged boiler is so-called because it comes as a complete package with burner, level controls, feed pump, and all necessary boiler fittings and mountings. Once delivered to the site it requires only the steam, water, and blowdown pipework, fuel supply, and electrical connections to be made
Devotion Boiler keeps improving the production process and quality control system, as well as updating its manufacturing facilities and machines. Devotion Boiler manufacturing base in Guangzhou, China comprises of three plants. Plant No.1 makes pressurized boilers, that is steam boilers and pressurized hot water boilers.
Steam Boiler . Steam output from 2.000 to 25.000 kg/h, rated pressure upto 18 bar (higher rated pressures on request), three pass (1 pass in the firetube, 2 passes in the pipe nest), wet back. For steam output ≥ a 10.000 kg/h, Fox corrugated firetube as a standard, on request for higher outputs.
Generally, a steam boiler is a type of closed container, designed with steel for heating the water to generate steam by some energy source like burning of fuel with eventually. The vapor generated may be delivered at low-pressure for the industrial progression work in sugar industries, cotton mills, and for generating steaming water that can be utilized for heat up fixing at much low-force.
Steam boiler with outputs of up to 120 t/h, industry, new build and modernisation projects Vitomax 200-HS High pressure steam boiler, steam output: 0.5 - 4 t/h, permissible operating pressure 6 to 25 bar, three-pass boiler, for commerce, industry, new build and modernisation projects
IBR Three Pass Steam Boiler. Abiding by the ethical norms of the industry, we are engaged in manufacturing and supplying Three Pass Steam Boiler.These Boilers are suited to meet the rapidly changing & undependable energy situations and gives rated output on any solid fuel like coal, wood, lignite, husk, bio gas, pet coke, saw dust and others.
BBS three-pass steam boilers are exceptional due to their high levels of efficiency, safety, robust design and minimal operating requirements. That is why they are found in many industrial sectors. Anyone who is looking for quality at a reasonable price opts for a BBS three-pass boiler.
