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 high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes
According to steam character, steam boiler can be divided into saturated steam boiler and superheated steam boiler. In a boiler, energy from the fuel is transfered to liquid water in order to create steam. At first, cold water gets warmer and receives energy in the form of “sensible heat”, right until the boiling point.
Author: Chemical Engineer Indeck Superheat Boilers Meet Short Term Need for Turnaround, Outages and Emergencies in Petrochemical, Refinery and Processing Industries. Why Select an Indeck Superheat Boiler? Indeck’s 75,000 pph superheat boilers have large heating transfer surface areas for increased boiler efficiency and are designed to maintain lower furnace pressure drop.
3. Steam Superheat Temperature Control . The steam superheat temperature is controlled by adjusting the quantity of water sprayed into the steam following the super heater. This water is supplied by the boiler feed water pumps as pressures in excess of 3,000 …
Superheater—tubes located near the boiler outlet that increase (superheat) the temperature of the steam, p. 297. Waste heat boiler—a device that uses waste heat from a process to produce steam, p. 297. Water tube boiler—a type of boiler that contains water-filled tubes …
Jan 10, 2018· Types of Superheater Boiler - Superheater is a subcritical boiler component that serves to heat the saturated steam, at constant working pressure, so it becomes superheated steam. In its development since the beginning of the 20th century, along with various boiler design races, some engineering experts patented the design of different superheater.
Our automatic water boiler is energy efficient so that you have constant boiling water, perfect for tea, coffee and other hot beverages as well as convenience foods. Our water boiler features completely automatic filling and heating with a built in electronic controller to …
There are twenty-two primary reasons for tube failures in a boiler, which can be classified under six major groups. They can be analyzed and corrective and preventive action can taken. Good operating and maintenance practice reduces tube failures. Tube failures during the initial operation period, the normal operation period, and after ten to fifteen years operation show different trends.
Re: Technical question - fire tubes in boilers Author: SR_Krause You might be interested in some of the turn-of-the-last-century experiments by Baldwin (in particular) with various tweaks on the fire tube boiler, the Santa Fe experiment in jointed boilers (discussed on TO, I didn't find the link quickly), and application of water tube boilers
not need high maintenance, boiler tube, add-on devices if the boiler is designed for optimum flue gas velocities in the first place. Each boiler pass should be designed with a cross sectional area to achieve optimal flue gas velocity, which in turn maximizes heat transfer while also minimizing performance robbing soot build-up within the tubes.
