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 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.
Energy can be recovered from exhaust gases by transferring thermal energy from the high-temperature gases to boiler feedwater, or to the combustion air entering the boiler. Another aspect of exhaust-gas energy management, which is the focus here, is combustion management.
Exhaust gas boilers on auxiliary engines Figure 1: Schematics of traditional main- and auxiliary engine set up, with exhaust gas boiler on both, source: MEPC 68/INF.16 Exhaust gas boilers recover the heat from the exhaust gas of auxiliary diesel engines to generate steam and/or hot water, or …
File Size: 296KB Part number EVG-E001-A/1015 3 ™ gas-fired water boiler — Application Guide The figure below represents a general common venting approach. The Vent system for a Category II Evergreen boiler is considered a Designed / Engineered vent system and should be designed by a professional
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.
Apr 22, 2020· As the source of central heating and hot water, a functional boiler is essential to any British home – particularly during the colder months. If you are experiencing an issue with your boiler, this guide to common boiler problems may help you diagnose the issue before reaching for the Yellow Pages and calling in outside help for an expensive emergency service.
Oct 01, 2018· 1. Lower the Stack Temperature. Lowering stack temperatures may be as simple as a day/night set back that lowers the operating pressure on steam boilers or operating temperature on hydronic boilers when idling at night or on mild spring and fall days.. 2. Install an Economizer. An economizer uses the otherwise wasted hot flue gas to heat feedwater on its way to the boiler.
Nov 15, 2016· Boiler Rooms Need Proper Air Intake. The proper operation of your facility’s boiler depends on upon the support of the systems connecting to it. Systems including the boiler room air supply, flue gas system exhaust, power distribution grid, fuel delivery system, and the hot water distribution system.
Part number 550-100-133/1015 3 ™ gas-fired water boiler — Vent Addendum Direct Exhaust (Category II Only) Venting – general Evergreen Boilers must be vented and supplied with combustion and ventilation air using piping and methods described in this adden-
Aug 13, 2018· When fuel is burned in a boiler, it produces flue gas, similar to the exhaust from your car. This gas leaves the combustion chamber and enters the flue passages. The combustion chamber and flue passages (called the heat exchanger) are surrounded by water… the same water that is circulated throughout your home to deliver heat.
