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.
A typical Cochran boiler, as illustrated, might be 15 feet (4.57 m) high and 7 feet (2.13 m) in diameter, giving a heating surface of 500 square feet (46.45 m 2), and a grate area of 24 square feet (2.23 m 2). Working pressure is between 100 and 125 psi (6.9 and 8.6 bar; 690 and 860 kPa).
Packaged Boilerhouses · Economisers Cochran Boiler Definition: Cochran boiler is a fire tube boiler (Fire inside the boiler and water surrounding to them) in which coal or gases as a working fluid is used, for generating the steam and that steam further used for several purposes.
Flue Gas Boiler. Flue Gas boilers are the significant energy saving equipment, utilize the heat in flue gas from combustion processes or hot extract air from industrial processes to generate hot water or saturated steam Otherwise, the flue gas boiler could be used in oil gas fired combined cycle units, and take advantage of the high temperature flue gas heat discharged by gas turbine
The world famous trade names of the Wee Chieftain and Thermax boilers are available as either an industrial steam boiler or an industrial hot water boiler. You could also chose from our Borderer, Clansman, Calpac or Coalmaster industrial boiler ranges, each one would be tailored to your specific energy requirements and needs by our excellent
Cochran Boiler In the furnace, a fire door and a damper is provided for feeding coal to the grates and controlling the amount of air entering the grate, respectively. Adjacent to the furnace, the boiler has a fire brick lined combustion chamber which is connected to the furnace through a small flue pipe.
Nov 20, 2019· In Cochran boiler first the fuel is inserted into the firebox and placed on the grate. The fuel is ignited through the fire hole provided at the right bottom of the boiler. The fuel is burnt in the firebox, and due to the burning of the fuel, smoke and hot flue gases emerge out. The hot flue gases enter into the combustion chamber through flue pipes.
ss panel flue type gas water boilers – Coal / Gas Boiler . ss panel flue type gas water boilers in Rice Mill. In rice mill, ss panel flue type gas water boilers is used for starch liquidation and pasting. The needed steam pressure is between 0.3MPa and 0.6MPa. The best fuel for steam boiler is rice husk, which can save cost.
leading Independent Insurance Company, in addition to Cochran’s own ISO 9001-compliant quality procedures. Cochran’s ST28 packaged steam boiler offers the following key features and optional upgrades: n Emissions fully compliant with MCPD. n Further NO x reductions achievable with the introduction of flue gas recirculation.
May 02, 2016· Flue gases start flowing into the hemispherical dome shaped combustion chamber. This flue gases further moves into the fire pipes. Heat is exchange from flue gases to the water into the fire tubes. The steam produce collected into the upper side of the shell and taken out by when required pressure generated.
Mar 19, 2019· Cochran boiler consists of a cylindrical shell with its crown having a spherical shape. The furnace is also hemispherical in shape. The grate is also placed at the bottom of the furnace and the ash-pit is located below the grate.
In the flued boiler, any sediment fell past the furnace flue and settled out at the bottom of the boiler shell, where it had less effect.  In model engineering , the Cornish boiler, particularly when fitted with Galloway tubes ( see Lancashire Boiler, below ), is an excellent choice for gas-fired boilers and model steam …
