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.
File Size: 105KB Inert gas generator (IGG) A device, similar to a boiler, in which fuel is burnt to create exhaust gases which contain less than 5% oxygen. Inert gas generator consists of a combined burner and scrubber, both seawater-cooled.Marine diesel or heavy fuel oil is burnt to …
1.Inert gas is mainly used during the discharge of the vessel. 2.The Boiler is anyway running during the discharge of cargo to power the turbines of the cargo oil pumps. Hence just by treating the exhaust gas of this boiler would generate the Inert Gas. When Is Inert Gas Plant Used
Inert Gas System (IGS) An inert gas plant and inert gas distribution system together with means for preventing backflow of cargo gases to the machinery spaces, fixed and portable measuring instruments and control devices. SOLAS International Convention for the Safety of Life at Sea
May 24, 2020· The inert gas system is essential for ship safety, it does not just provide inert gas with oxygen 5% by volume but also helps maintain positive pressure in tanks. Component and Layout of Inert Gas System. A typical inert gas system consists of the following systems:-Boiler Uptake Valve: It is the supply valve for the flue gas to the inert gas
The general arrangement of the inert gas system is as follows: The inert gas generator-Exhaust gas from the main boiler or the auxiliary boiler is used. Scrubber; This is installed to clean and cool the exhaust gas. Working of scrubber: The exhaust gas coming out of the boiler enter the scrubber and passes through a water seal in a water tank
Kangrim Inert Gas Systems, Generators and Boilers. Kangrim has been a key supplier of Inert Gas Systems and Inert Gas Generators and Boilers for many Korean and Chinese built vessels since the early 2000s, with their simple design and attractive price point for their systems.
Inert gas system: The system provides an inert gas (e.g., nitrogen) blanket in tanks in order to displace oxygen and prevent the development of a flammable atmosphere, which could enable a fire or explosion. • Relief system: Comprised of, for example, pressure relief valves and/or rupture disks on individual process lines and/or vessels. The
Inert gas generator (IGG) refers to machinery on board marine product tankers.Inert gas generators consist distinctively of a gas producer and a scrubbing system. Process. Diesel is burned using atmospheric air in a combustion chamber and the exhaust gas collected, the resulting exhaust gas contains less than 5% oxygen, thereby creating "inert gas", which mainly consist of Nitrogen and partly
Author: Alfa Laval Jan 09, 2018· Inert Gas systems is mandatory technology for oil and chemical tankers with existing vessels > 20,000 tonnes and for new vessels > 8,000 tonnes. Installing an inert gas system is equal to essential protection of your vessel and people’s safety.
Click to view14:58Oct 07, 2018· Oil tankers carry oil of different grades and quality, having property to produce flammable vapors and gases when loaded for transportation. Even with no car
The following components are used in a typical inert gas system in oil tankers: Exhaust gases source: Inert gas source is taken from exhaust uptakes of boiler or main engine as contains flue gases in it. Inert gas isolating valve:It serve as the supply valve from uptake to the rest of the system isolating both the systems when not in use. Scrubbing tower:Flue gas enters the scrub tower from
