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.
Apr 30, 2012· In preparation for the upcoming season, we dissembled and inspected the 765's MB-type stoker. Here it is running on shop air shortly before re-installation. A steam locomotive is …

File Size: 881KB May 16, 2020· Boiler workers and operators, maintenance workers, and workers who repaired or replaced the boilers or its parts were all at risk of being exposed to asbestos. Over time, the asbestos in Riley Stoker boilers could have deteriorated and become exposed, at which time, fibers may have come loose and led to inhalation by workers.
The number and size of the tubes, the type of fuel, and the overall physical dimensions of the boiler will all vary depending on what the boiler is designed to produce (water, steam, or heat) and the industry it is intended to serve (e.g., utility, industrial, medical).
Sep 21, 2017· Besides the other answer, the term “Stoker" (naval term) is another name for “fireman” (merchant Navy term), though the question is not too clear (always best to give more information on questions than too little). In coal burning ships, the Stoke
On the classification of this stoker boiler type, coal is fed to the end of steel grate that moves. When the grate moves along the furnace, coal is expected to be burned before it falls on the other end as ash. In this stoker boiler type, to adjust the baffles, air damper and grate need certain skill level; therefore, personnel in charge must be capable and qualified.
This type of damage is common when boiler convection sections are mechanically cleaned of hard buildups, or when refractory repairs or repairs to other tubes are made. The simple drop of a hand tool can result in thousands of dollars in repairs as well as potential downtime of the unit.
3. Type B double-wall metal vent pipe — see vent manufacturer’s recommendation for clearances to combustible material. Small space installations 1. When the boiler is located in a closet or small space, provide clearances no less than those shown in Figure 1. The clearances are required to any surface, whether combustible or non-combustible
