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.
The steam quality level used in some food processes. Steam is filtered immediately before use. Highest Levels of Steam Quality (Clean & Pure Steam) Boiler water has undergone treatment to remove potential contaminants; steam is then generated & transported using stainless steel equipment to prevent contamination during distribution.
Another boiler fuel is referred to as biomass. Biomass is renewable organic matter. Examples of biomass include fast-growing trees and plants, wood and wood waste, agricultural crops and residue, aquatic plants and algae, animal wastes, and organic municipal and industrial wastes. RDF is a potentially valuable energy source.
Where organics come from. There are two primary sources of carbon-based molecules in a boiler or in the steam it produces: compounds that enter with makeup water and organic treatment chemicals.
File Size: 936KB Boiler water carry-over is the contamination of the steam with boiler-water solids. Bubbles or froth actually build up on the surface of the boiler water and pass out with the steam. This is called foaming and it is caused by high concentration of any solids in the boiler water. It is generally believed, however, that specific substances such as alkalis, oils, fats, greases, certain types of
Hydro-Steam™ 9150. Steam Boiler Cleaner & Dispersant. Hydro-Steam™ 9150 is an alkaline, multi-purpose product formulated to gently and effectively remove and disperse scale, corrosion products, and organic matter in residential and small commercial steam boilers.
Natural organic matter (NOM), which consists of organic chemicals that pass through the pretreatment equipment and wind up in the boiler feedwater and steam. Treatment chemicals added to the
In thermally enhanced oil recovery operations, particularly in steam-assisted gravity drainage (SAGD), boiler blowdown (BBD) containing high concentrations of dissolved organic matter (DOM), dissolved silica, and total dissolved solids (TDS) is generated. To develop efficient tools for managing this blowdown, a detailed understanding of its chemistry is required. In this study, BBD was
Organic Matter. Carryover, foaming, deposits can clog piping, and cause corrosion. Clarification; filtration, and chemical treatment. Found mostly in surface waters, caused by rotting vegetation, and farm run offs. Organics break down to form organic acids. Results in low …
Common causes of foaming are excessive solids or alkalinity, and the presence of organic matter such as oil. Keeping dissolved solids below the concentration that causes foaming requires continuous or periodic blowdown of the boiler. High boiler water alkalinity increases the potential for foaming, particularly in the presence of suspended matter.
The boiler treatment program aims at control of seven broad classifications of impurities: suspended solids, hardness, alkalinity, silica, total dissolved solids (TDS), organic matter, and gases. The extent to which each of the unit processes applicable to boiler makeup …
Certain species of organic matter, when in large concen-trations, can cause the boiler water to foam, leading to carry-over of boiler water solids into the steam and in con - sequence to deposits in the superheater and in the turbine.
