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.
Both heat generators are connected to the heating system when providing heating water or DHW. Gas engine units in biogas operation Viessmann Kraft-Wärme-Kopplung GmbH (formerly ESS - Energie Systeme & Service GmbH) is the Viessmann Group's CHP specialist and has been a member of the Group since 2008.
If the cogeneration system is installed as a retrofit, the system must be designed so that the existing energy conversion systems, such as boilers, can still be used. In such a circumstance, the options for cogeneration system would depend on whether the system is a retrofit or a new installation. 19.7.8 Electricity buy-back
The waste gases coming out of the furnace is utilized in a boiler to generate steam, which drives the turbine to produce electricity. 7.5 Factors Influencing Cogeneration Choice The selection and operating scheme of a cogeneration system is very much site-specific and depends on several factors, as described below:
A biogas cogeneration system comprises two parts: one for fermentation and production of biogas, which includes one or more fermenters, and the other to transform biogas into energy, which the actual cogeneration system. Biogas is a mixture primarily made up by methane, carbon dioxide, and other minor components, which is obtained from
File Size: 672KB Biogas is run through turbo-blowers to provide oxygen to generate mixed liquor suspended solids in the aeration tank. This is to ensure that there is a sufficient quantity of active microorganisms to consume organic pollutants. Biogas was used for this process before the …
Cogeneration installations are usually sited as near as possible to the place where the heat is consumed and, ideally, are built to a size to meet the heat demand. Otherwise an additional boiler will be necessary, and the environmental advantages will be partly hindered. This is the central and most fundamental principle cogeneration.
Cogeneration, also known as combined heat and power (CHP), is a highly efficient process that generates electricity and heat simultaneously. By utilizing the exhaust energy from gas turbines, useful steam can be generated in a heat exchanger which can then be used in any number of applications, all with no additional fuel consumption.
Biogas from Regenerative Raw Material and Biogas Plants. Biogas is the product of the anaerobic fermentation of organic material in a fermenter. This gas has a CH4 methane content of 45-70 percent. During the combustion, the amount of emitted CO 2 merely corresponds to the amount that the substrates absorbed during growth. Cogeneration plants
Biogas cogeneration/Combined Heat & Power (CHP) units usually run on methane gas that is created by an anaerobic digestion process (AD). These microbes feed off carbohydrates and fats, normally in animal waste producing methane and carbon dioxides as metabolic waste products.
A biogas cogeneration system has two parts: one for the fermentation and production of biogas, which includes one or more fermenters, and the other to transform biogas into energy, which is the actual cogeneration system.
