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.

Aalborg AV-6N heat recovery boiler improves overall efficiency Aalborg AV-6N is the optimum solution for high-performance heat recovery systems.
heat gas recovery systems to capture and use some of the energy in the flue gas. For natural gas-based systems, the amount of heat contained in the flue gases as a percentage of the heat input in a heating system can be estimated by using Figure 1. Exhaust gas loss or waste heat depends on flue gas temperature and its mass flow,
Exhaust heat from combustion typically leaving the stack and into the atmosphere is instead transferred from the exhaust stream by means of a Cain economizer. This lost BTU is now captured and saved to various heat sinks such as boiler feedwater, cold makeup water, process water, swimming pool water, glycol, and thermal fluids.
8 Waste Heat Recovery System (WHRS) for Reduction of Fuel Consumption, Emission and EEDI increasing the exhaust gas temperature before the boiler without using a power turbine. When applying the steam turbine (ST) as a stand-alone solution, the exhaust gas bypass stream is mixed with the exhaust outlet from the turbocharger(s),
File Size: 2MB The first step in planning to install a waste heat recovery system (WHRS) is to work out the net available waste heat that can be used to generate power. 2.1.1. In a cement plant, waste heat is available mainly from kiln exhaust gases and vent air from the clinker cooler. Waste heat is also available from the exhaust of diesel engines of DG Set.
Dec 09, 2015· Exhaust gas boiler (EGB or EGE) or economiser described in this article is a smoke tube boiler with steam space, used for heat recovery from main engine exhaust gas. An illustration of the boiler is shown in figure below.
From waste to win. The recovery of waste heat is a unique opportunity that benefits operating economy as much as it does the environment. With as much as 35% of an engine’s fuel energy going into the exhaust flow as waste heat, there are substantial savings to be made when that energy is recovered.
The temperature of boiler exhaust flue gas normally ranges from 120 to 150 °C in coal-fired power plant (CFPP). The heat loss of exhaust flue gas accounts for approximately 50–80% of the total boiler heat loss and 3–8% of the total energy input of CFPP . This means that recovering waste heat from boiler exhaust flue gas could improve

Harbour conditions Economizer after aux. engines. For new installations or retrofit, an efficient exhaust gas economizer utilizing the heat in the exhaust gas from the auxiliary engines during port stays will significantly reduce the oil consumption for the oil-fired boiler.
Specifically, AFUE is the ratio of annual heat output of the furnace or boiler compared to the total annual fossil fuel energy consumed by a furnace or boiler. An AFUE of 90% means that 90% of the energy in the fuel becomes heat for the home and the other 10% escapes up the chimney and elsewhere.
