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.
Fire Tube Boiler Diagram. These boilers include a water level indicator; a pressure gauge, steam stop tap security tap, & a manhole like mountings for providing security as well as simplicity of working. The Fuel burns on the grate of the firebox in the boiler and the resultant hot-flue gases are permitted to flow in the region of cross tubes.
Dec 07, 2016· Water Tube Boilers. Unlike fire tube boiler, where the hot gas is circulated through tubes to heat water in a tank, water tube boilers involve running water through tubes surrounded by a heated tank. These types of boiler are generally considered safer than fire tube designs and typically require less frequent maintenance.
Author: wareboilers May 02, 2020· Fire Tube Boiler: In a fire tube boiler, hot gas passes through the pipes and boiler feed water is inside the shell to be converted into steam. Fire tube boilers are usually used for relatively small steam capacities with low to moderate steam pressures.
Boiler Drum level control – Instrumentation and ControlMay 02, 2020UV type fire detectors | Instrumentation and ControlJun 07, 2019Fire-Tube-Steam-Boiler | Instrumentation and ControlMay 30, 2019fire tube | Instrumentation and Control EngineeringMay 23, 2019See more results In water-tube boilers, the fluid with the higher density flows through the tubes and the fluid of lower density flows through a larger diameter external to the tubes (combustion chamber), ultimately resulting in water-tube boilers having higher overall heat transfer coefficient when compared to a fire-tube condensing boiler of the same size and
Mar 19, 2016· The main difference between fire tube and water tube is that in fire tube boiler the flue gases flow in the tubes and water flows from the shell and in water tube boiler, water flows from the tubes and the flue gases from the shell or passes over the tubes. This is …
There are a number of considerations to factor when determining the best boiler for your steam generation needs like operating pressure, steam pounds/hour output, demand fluctuation, general application requirments and total cost of ownership, etc. Two primary boiler types, the firetube boiler and the watertube boiler, are essentially opposite in design. The firetube boiler passes combustion
Water Tube Boiler Components of Water Tube Boiler. The water tube boiler can be built with boiler shell, burner, mud drum or mud ring, furnace, safety valve, strainer, sight glass, feed check valve, steam stop valve, etc. Boiler Shell: This shell is the external cylindrical part of a pressure container.
The universal type of steam boilers is the smoke tube or fire tube boiler where the heat and gases of combustion (from furnace) pass through tubes that are enclosed by water. While in water tube boilers, water passes through tubes. Mostly used boiler in small and medium industries with different fuels and steam pressure requirements. Types of
Water-tube boiler: The water-tube boiler is those boiler in which the water is present inside the tubes and fire or hot gases surround these fire tubes. The examples of water tube boilers are a La-Mont, Benson, Stirling, Babcock and Wilcox, Yarrow and Loeffler boiler.
Apr 23, 2016· The difference between fire tube boiler and water tube boiler can be done on various points. These points includes types of fluid flows within the tubes, steam generation rate, floor area required for the steam generation, transportation, efficiency, fluctuating loads, operating cost etc. the knowledge of the difference about these two boiler is very crucial.
Jun 13, 2013· Boilers come in all different types, sizes, and shapes and are classified by configuration of the furnace, or firesides, and the watertubes, or water holding volume. The two main boiler types consist of firetube and watertube boilers, and deciding which of the two will best fit your process needs is not as easy as it may seem. It is like comparing
