Introduction of WNS gas / oil fired steam boiler:

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.

Technical advantages:

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.

Cyclone Separator Design, Components and How it Works -

Reverse Flow Cyclone separators are cone shaped, gas enters at the top of the separator body flows downwards, then flows back upwards and is discharged. For Axial Flow Cyclones Separators, gas enters at one end and is discharged at the opposite end. The axial flow design is not as common as the reverse flow design.

Fly Ash Separation Technology and its Potential Applicatio

Our separation process system consists of a feeder, an air blower, a centrifugal separator with an adjustable fan speed, a cyclone separator, a filter bag, and an induced draft fan as shown in Figure 2. Figure 2 Photo and schematic diagram of the fly ash separation system at NICE The separation capacity of this lab scale process is about 20 kg/hour.

coal biomass wood fired 6 ton steam boil

6 Ton 10 ton Biomass olive husk fired steam boiler. 6 Ton 10 ton Biomass olive husk fired steam boiler 1. The hearth is designed with a cyclone reburning chamber, and high temperature fume achieves the effects of primary dedusting energy conservation and environmental protection through high speed revolution, mixed combustion and dust separation.

Cyclone Boiler - an overview | ScienceDirect Topi

Cyclone coal combustion technology requires less preprocessing of the coal and allows for the burning of lower-rank coals with higher moisture and ash contents. Cyclone boilers use burner design and placement (i.e., several water-cooled horizontal burners) to produce high-temperature flames that circulate in a cyclonic pattern.

Industrial Cyclones - Cyclone Separator - Fish

Industrial Cyclones are a technology that uses cyclonic separation as its method of removing particulates from an air, gas or liquid stream, without the use of filters, through vortex separation…

Multi Cyclone Dust Collectors, कोयला फायर्ड बॉयलर in C I

Beyond the concept of conventional Cyclone Separators we provide highly appreciated Multi Cyclone Dust Collectors (MDC) with higher separation ratio. It separates dust in a dry state from flue gas with a higher efficiency through the application of inertial and gravitational forces.

Cyclone fired wet bottom boilers | IEA Clean Coal Cent

Jan 20, 2018· Cyclone-fired boilers are used for coals with a low ash fusion temperature which are difficult to use with PCC. 80-90% of the ash leaves the bottom of the boiler as a molten slag, thus reducing the load of fly ash passing through the heat transfer sections to the precipitator or fabric filter to just 10-20% of that present.
