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.
FLUIDIZED BED COMBUSTION While the pulverized coal-fired boiler represents the most efficient type of coal- fired power plant, there are alternatives. One of these is the fluidized bed boiler. This type of combustion system is capable of burning a much wider range of fuels than a PC plant. It operates at a lower temperature, making…
Circulating Fluidized Bed (CFB) combustion boilers gives the flexibility for combustion of a wide range of coals and alternative fuel sources. All this without compromising efficiency and with reduced emissions. This article gives a brief description of the working of a CFB boiler. At the bottom of the boiler furnace there is a bed of inert material. Bed is where the coal or fuel spreads. Air
Drawing upon our extensive technical expertise and operating experience, B&W developed the Internal Recirculation Circulating Fluidized-Bed (IR-CFB) boiler which is the technology of choice for power plant owners seeking economy, reliability and flexibility. In addition, load-following capabilities are attainable with B&W’s in-bed heat exchanger technology.
Author: Sumitomo SHI FW David A. Tillman, in Coal-Fired Electricity and Emissions Control, 2018. 2.1.3 Control of NO x. Fluidized bed boilers of all types are, by virtue of their combustion temperatures, low NO x generators. Operating the reactors at temperatures ≤1700°F virtually eliminates formation of any thermal NO x.All NO x is generated from the conversion of fuel nitrogen.
“ (FBC) Fluidized bed combustion is a combustion technology used to burn solid fuels in steam boilers.” In Fluidized Bed Combustion Boiler technology When air or gas is passed through an inert bed of solid particles such as sand supported on a fine mesh or grid, the air initially will seek a path of least resistance and pass upward through the sand.
BASUKI PRATAMA ENGINEERING leading producer of non polluting and high efficiency coal fired steam boilers and thermal oil heaters using fluidized bed combustor or. fluidized bed coal boiler on sale – tjskl.org.cn. Fluidized bed combustion boiler : 1.Large heating …
When the Å agisza power plant began commercial operation in late June 2009, it marked the beginning of a new era in the evolution of circulating fluidized bed (CFB) technology. At the heart of
biomass fuel fired steam boiler Liquid &Gasesus fuel Fired Boilers Our Oil & Gas fuel fired Boiler are three pass, wet back, fully packaged boilers, equipped with monobloc or dual blocks burners to deliver high combustion and thermal efficiencies.
University of Missouri Missouri, USA. B&W designed, engineered and supplied a biomass-fueled bubbling fluidized bed (BFB) boiler to replace the University of Missouri’s existing coal-fired boiler, and to provide the university campus with electricity and steam for heating and other uses.
Fluidized bed combustion (FBC) is a combustion technology used to burn solid fuels.. In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials (sand, limestone etc.) through which jets of air are blown …
BASUKI Combi Boiler combined water tube design and the latest combustion technology for maximum efficiency, durability, and reliability. Powered by an enhanced fluidized bed design, our Combi Boiler provides up to 99% combustion efficiency, minimized fuel-air contact and pre-heater economizer features that delivers improved performance with lower operational cost.
