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.
Author: Li Feng, Duanmu Lin, Fu Lin, Zhao Xiling Waste heat recovery is a process that involves capturing of heat exhausted by an existing industrial process for other heating applications, including power generation. Technavio forecasted the global waste heat recovery market in oil and gas industry to grow at a CAGR of 7.6% during the period 2014-2019  .
in CHP applications because the exhaust heat can either be recovered in a heat recovery boiler, or the hot exhaust gases can be used directly. There are over 360 sites in the United States that currently use microturbines for CHP. These microturbine sites represent over 8% of the total number of CHP sites in the United States, accounting for 92 MW

Cited by: 68 However, boiler efficiency can be improved by 3-13.4% (based on a low calorific value) by applying some heat recovery technologies, such as condensing heat, absorption heat pump heat, and total
Full-open absorption heat pump (FOAHP) is a new approach to total heat recovery of gas boiler flue gas. With the flue gas dehumidified deeply, the latent heat can be recovered efficiently.
Alfa Laval Aalborg's heat recovery boiler utilise the energy otherwise wasted in the exhaust gas to generate steam or heat water, which e.g. can be used for district heating/cooling networks, the food processing industry and laundry, refinery or textile factories or other types of industrial processes. This way the plant’s total efficiency is
Cited by: 1 Total COP for Heat Recovery + Chilled Water The ability to capture and use this waste heat is known as heat recovery, since the waste heat is recovered and used for other purposes, including heating hot water. Although this process is not new, the benefits of heat …
Total heat recovery of gas boiler by absorption heat . A new technology for condensing heat recovery from gas boiler is presented. Absorption heat pump and direct-contact heat exchanger are combined in this system. Field test shows that the temperature of the flue gas can be cooled below 30 °C.
Feb 13, 2003· RE: Heat absorption rate from furnace to boiler dooron (Mechanical) 12 Feb 03 17:52 very complex, including radiation convection fouling factors and loss of energy to exhaust gases, if heated by gas, or view factors if heated by electric.
Sep 24, 2019· Apart from absorption cooling, absorption heating technologies are also widely used for waste heat recovery and renewable energy utilization. Waste heat recovery in district heating systems covers cogeneration heat recovery and flue gas heat recovery, which can improve the overall energy efficiency by 5–30%.
Author: Wei Wu, Xianting Li, Tian You Total heat recovery of gas boiler by absorption heat pump and direct-contact heat exchanger. This paper presents a new technology which combines the absorption heat pump and the direct-contact heat exchanger. Based on the analysis of natural gas features and thermal efficiency of the gas boilers, it analyzes existing and new techniques for heat
