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.
A boiler explosion is a catastrophic failure of a boiler.As seen today, [when?] boiler explosions are of two kinds. One kind is a failure of the pressure parts of the steam and water sides. There can be many different causes, such as failure of the safety valve, corrosion of critical parts of the boiler, or low water level. Corrosion along the edges of lap joints was a common cause of early
Answer / viraf b. karanjawala. the probable causes of boiler backfire are 1) outlet damper partially/fully closed, 2) Improper tuning of the burner 3) accumulation of combustible gases in pockets with in the
In a boat surrounded by water, fire may be last on a crew member's list of suspected onboard ship hazards. However, ships are susceptible to fires due to the amount of heavy machinery found in their boiler rooms and other areas.
The boiler of the ill-fated ferry.boat Vew-Jersey was raised to.day. Ono of the furnace doors was found open. The U. S. Boiler Inspeotor examined the interior of the boiler and found it to bo very
Capacity: 376 passengers and cargo Aug 10, 2015· Central heating Boiler pilot light not staying on? The most common cause of the problem. Need spares ? Boiler Pilot won't light / Replacing the thermocouple if the pilot won’t stay lit
Mar 14, 2014· Preventing Dry-firing in Boilers. March 14, 2014. No Comments. It’s a familiar tale in the boiler industry: something goes wrong with the feedwater supply to a boiler, the boiler runs out of water, and it does not trip offline. The steam pressure goes to zero (because no water is in the boiler), so the boiler ramps up to high fire to make up
When BoatUS Marine Insurance turns a claim over to a fire investigator, his or her task is to find both. They don't always succeed — about eight percent of the time, no cause can be assigned. But it should come as no surprise that, in those cases where a cause can be determined, at least half of all boat fires originate around the motor.
In modern boiler, fire tube boiler is designed automatic. If water level reaches minimum low level, fire tube boiler will sound alarm and automatically shut down. Another cause of failure in fire tube boiler is the boiler age is very old. Material of boiler is fatigue so cause material strength can not resist the pressure.
Aug 27, 2015· This may result in boiler soot fire or boiler uptake fire. When an uptake fire is suspected, never soot blow the economiser. Soot blow with steam causes steam to convert as hydrogen gas and result in metal fire. Preventive Actions. Regularly inspect boiler …
The cause of the high temperature in this case was threefold. First, primary air velocities were high, which drove the fuel deep into the furnace, away from the secondary air provided at the burners.
Fire on boat - really bad. On 2017-02-19 16:10:17.694467 by Nick I work on a boat and on hear we have a Sabre boiler with a Beckett Series oil burner, my question is I got on the boat a few days ago and was told that their was a lot of black smoke coming from stack for boiler, so I shut it down a started to inspect it, found that there was a
