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.

40 transfer mechanisms; in practice, conduction/convection dominate lower temperature processes, 87 Hybrid boiler systems combining a fuel-based boiler with an electric-based boiler using off-peak 157 has contributed in development of innovative technologies that have resulted in substantial

Recovery boiler - Wikiped

Combustion of the organic portion of chemicals produces heat. In the recovery boiler, heat is used to produce high pressure steam, which is used to generate electricity in a turbine. The turbine exhaust, low pressure steam is used for process heating. Combustion of black liquor in the recovery boiler furnace needs to be controlled carefully.

Anaerobic digestion - Wikiped

The four key stages of anaerobic digestion involve hydrolysis, acidogenesis, acetogenesis and methanogenesis. The overall process can be described by the chemical reaction, where organic material such as glucose is biochemically digested into carbon dioxide (CO 2) and methane (CH 4) by the anaerobic microorganisms.

Science and technology of ammonia combustion - ScienceDire

However, in Skreiberg's mechanism and most other kinetic mechanisms derived from it, these reactions are not modeled as pressure-dependent three body reactions. It is worth noting that this kinetics of NH i combination reactions which produce N 2 H i species has not yet been well characterized despite evidence of its importance in rich and low temperature ammonia flames [86] , [104] , [105] .

Quenching - an overview | ScienceDirect Topi

Quenching bath temperature also influences crystallization temperature. It is reported that decrease in quenching bath temperature (increasing in the cooling rate) results in decrease of crystallization temperature. 9, 10 Thus, the higher cooling rate can extend the gap between the cloud point and crystallization temperature (liquid–liquid phase separation region).

Corrosion Prevention for Metals - Thought

Nov 16, 2018· Methods to reduce the sulfur, chloride, or oxygen content in the surrounding environment can limit the speed of metal corrosion. For example, feed water for water boilers can be treated with softeners or other chemical media to adjust the hardness, alkalinity or oxygen content in order to reduce corrosion on the interior of the unit.

Selective catalytic reduction - Wikiped

Before entering the catalyst chamber the ammonia, or other reductant (such as urea ), is injected and mixed with the gases. The chemical equation for a stoichiometric reaction using either anhydrous or aqueous ammonia for a selective catalytic reduction process is: 4NO + …


process relates to a specific chemical reaction. A mixture of ammonia and heated air is reacted in a catalytic converter to produce nitric oxide (NO) and water, as shown in Reaction 1. The most common catalyst consists of a 90 % platinum and 10 % rhodium gauze constructed from squares of fine wire. Up to 5 % palladium is also used.
