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.
Fouling (soot deposits) on the exhaust gas boiler tubes can result in soot fire, which in extreme cases can develop into iron fire that causes the entire boiler to burn. The soot particles in the exhaust gas boiler are unavoidable, since the exhaust gas contains soot particles. What can be made instead is preventing theContinue reading →
reduction of fuels quality and increasing the exhaust gas boiler efficiency had resulted in a recent year’s increase of incidents of fire. Figure No. 1 shows the statistical representation of exhaust gas boiler fire on ships under the DNV supervision . Data for the 1993 rd and 2003 were not collected, and so even after the 2005th year. Due
6 Soot Deposits and Fires in Exhaust gas Boilers quality and the above highly efficient and perhaps “overstretched” design, it also seemed that the tendency to fouling, i.e. soot deposits on the ex haust gas boiler tubes, had increased and, in some cases, had resulted in soot fires. In extreme cases, the soot
An Exhaust Gas Boiler is a type of heat recovering system on ships which allows the exhaust heat of the main engine to produce steam while going out in the atmosphere. Every system, which is operated at high temperature, always has a risk of fire.
Fire in exhaust gas boiler INSIGHT 181, 2006 01 FEB 2006. The following incident involving a fire in exhaust boilers occurred on board a bulk carrier a few years ago. The vessel berthed and the main engine was shut down. The feed water circulating system for the exhaust gas boiler was also isolated.
Author: TheSteamGenerator Exhaust Gas Boilers And Economisers Arrangement Auxiliary boilers on diesel main propulsion ships, other than tankers, are usually of composite form, enabling steam generation using oil firing or the exhaust gases from the diesel engine. With this arrangement the boiler acts as the heat exchanger and raises steam in its own drum.
A water tube exhaust gas boiler with forced water circulation designed for heat recovery from engine exhaust gas. The boiler is used in connection with one or more oil fired boilers which act as steam/water space. Water at saturation temperature is pumped from the oil fired boiler(s) into the exhaust gas boiler by the circulation pumps.
Mar 06, 2020· An Exhaust Gas Boiler is a type of heat recovering system on ships which allows the exhaust heat of the main engine to produce steam while going out in the atmosphere.. Every system, which is operated at high temperature, always has a risk of fire. This applies to EGB which has the inlet temperature of exhaust gases @ 300-400 deg. C.
A boiler typically uses a fuel such as natural gas, propane, or fuel oil in a vented combustion chamber, much like a furnace. except to provide fire blocking in accordance with Section R1003.19. Outside Opening Protection. Air exhaust and intake openings that terminate outdoors should be protected with corrosion-resistant screens
Apr 05, 2019· Exhaust Gas Boiler Fire causes and actions to be taken in such scenario are discussed in this article. If proper precaution and maintenance is done, such a scenario can be avoided easily. It has happened that fire have become so intense that it has lead to melting of the whole boiler.
