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.
Some of the materials included in Table 4.1 are presented in Fig. 4.1, which shows how steam temperature and pressure must vary to achieve the 100 000-h, creep-rupture life used as one of the criteria for materials’ selection. Super 304H, an advanced austenitic stainless steel, for a steam pressure of 4000 psig (277 bar) could operate with a mid-wall temperature of 1310 °F (710 °C) and
Author: J.M. Wheeldon, J.P. Shingledecker Dec 13, 2018· When it comes to installation, the refractory material used comes in two forms: firebricks and monolithic refractory. Firebricks. This refractory material has long been used over the years. The material is formed into bricks that are fired at very high temperatures in special insulated chambers. The material is usually lined in boilers or furnaces.
This depends on the material used in the boiler shell & firebox. Most small loco boilers are made of copper and for these boilers the best stay material is also copper. This is to avoid wasting away in the water space due to electrolysis. This action takes place when dissimilar metals are in contact and submerged in the boiler water.
When a packaged firetube boiler is used as a hot water unit: 1) It can be constructed of thinner material for a given pressure 2) An atmospheric burner must be used 3) It will not require an expansion tank 4) A water column and gauge glass is required 5) Forced circulation is required
Thus, virtually all of the materials used in the construction and repair of pressure parts of boilers fall into this classification. Some high-temperature, corrosion-resistant alloys of nickel and chromium with less than 50% iron are not, strictly speaking, steels, but are still occasionally used.

They also have a very high length through which the total pick up steam temperature takes places at each unit length. The length of tube and temperature pick-up needed to raise the steam to the required level of super heating calls for using different materials along the total length. These changes in material will have to be
Equipment in this category heats fluids to a specific temperature. The heated or vaporized fluid exits the boiler for use in various processes or heating applications. Boilers can be used for sanitation, food preparation, or to heat buildings. Boiler equipment comes in a variety of sizes.
used in high temperature boiler plant construction. Characterization of heat resistant materials Table 1 lists the international designations for selected SMST-Tubes materials having improved austenite stability. The stabil-ity of the austenite in CrNi and CrNiMo steels is achieved by increasing the nickel content over that of standard 18/8 CrNi
