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.
Asphalt Ingredients. So what is asphalt and its ingredients? There are actually two basic ingredients in asphalt. The first are aggregates; this is a mix of crushed stone, gravel, and sand. Aggregates make up about 95% of hot mix asphalt pavement. The other 5% is bitumen. Bitumen is the black or dark viscous material that holds the aggregates

The documents below are good references for asphalt driveways and parking lots. Regarding asphalt thicknesses for driveways, the first two documents are specifically about driveways, while the two documents on parking lots can also be referenced by assuming a low level of truck traffic for a driveway.

Asphalt concrete. Asphalt concrete, also referred to as tarmac, bitumen macadam, blacktop or rolled asphalt, is made up of mineral aggregate bound with asphalt and is used to surface roads, car parks, playgrounds and other areas where a long-lasting surface is needed.
5/56 Yelp reviews The story of asphalt goes far back in time – millions of years back. It started back when Earth’s surface consisted of a primordial soup teeming with microscopic algae and other small organisms. When these small creatures died, they sank to the ocean floor. Over time, these layers of sediment became buried deep below the earth’s crust and
Author: Luis AlvarezYT An asphalt driveway is often composed of base layers and top layers, though the most stable form of asphalt driveway will be created using full-depth asphalt. In general a 4″ thick asphalt layer is suitable for most driveways, but 5-6″ is recommended to support heavier vehicles and loads.

Asphalt, also known as bitumen (UK: / ˈ b ɪ tj ʊ m ɪ n /, US: / b ɪ ˈ tj uː m ə n, b aɪ-/), is a sticky, black, and highly viscous liquid or semi-solid form of petroleum.It may be found in natural deposits or may be a refined product, and is classed as a pitch.Before the 20th century, the term asphaltum was also used. The word is derived from the Ancient Greek ἄσφαλτος
Just like concrete, an asphalt driveway with a strong base can last for years. Asphalt with a firm base is just as strong as concrete and will hold up very well over time. Asphalt requires an 8-inch stone base and 2.5-inch blacktop because: Asphalt is flexible than concrete; thus it needs firm support.
Asphalt, black or brown petroleum-like material that has a consistency varying from viscous liquid to glassy solid. It is obtained either as a residue from the distillation of petroleum or from natural deposits. The principal application of asphalt is in road surfacing, which may be done in a variety of ways.
