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 Boilers Online Course Description: Conventional solid fuel power boilers burn the fuel in a fixed bed. In a fluidized bed boiler, hot air is blown at a high velocity up through a bed of sand, limestone, and ash causing the solid particles to fluidize, or behave like a liquid.
Frequency: 50Hz / 60Hz. Capacities: From 1.5 TPH to 10 TPH as STD offerings; from 12 to 20 TPH as Customized offerings. Firing fuels: Low and high calorific value coal, bagasse, wood.. We are offering Fluidized Bed Boiler to our clients. Note: Price will change as per Design, Capacity,
Book Edition: 1 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 …
The fluidized bed ensures almost complete combustion with the lowest emissions and the highest efficiency and availability. Bubbling Fluidized Bed (BFB) boilers ECOFLUID boilers are used for steam and power generation from biomass and different alternative fuels.
May 07, 2020 (The Expresswire) -- Global "Circulating Fluidized Bed Combustion Boiler (CFBC Boiler) Market" Global report 2020 presents a point by point
Fluidized Bed Combustion (FBC Boiler) “Fluidized bed combustion (FBC) is a combustion technology used to burn solid fuels.”. A bed of solid particles is said to be fluidized when the pressurized fluid (liquid or gas) is passed through the medium and causes the solid particles to behave like a fluid under certain conditions.. Fluidization causes the transformation of the state of solid
Circulating fluidized bed boilers disperse particles throughout the furnace for improved heat transfer. The solids are removed from the flue gas and returned to the combustion zone. In a bubbling bed boiler, primary combustion air is forced through nozzles in the bottom of the boiler at a velocity high enough to fluidize the solid particles in
Feb 02, 2016· In a fluidized bed boiler, hot air is blown at a high velocity up through a bed of sand, limestone, and ash causing the solid particles to fluidize, or behave like a liquid.

A cash flow model is developed to predict the economic consequences of an investment in an industrial coal-fired
Oct 22, 2013· Fluidized Bed Boilers: Design and Application attempts to address the need for a single source of information covering all major areas of fluidized bed boiler design and operation. It is based on the International Workshop on Design and Operation of Atmospheric Pressure Fluidized Bed Boilers, organized by the Center for Energy Studies
Yanguo Zhang, Hui Zhou, in Theory and Calculation of Heat Transfer in Furnaces, 2016. Abstract. The circulating fluidized bed boiler (CFB boiler) is the second-generation fluidized bed boiler, the updated version of the bubbling fluidized bed boiler (BFB boiler). In this chapter, fundamental concepts of fluidized beds (including the definition and characteristics of “fluidized bed
