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.

Advantages of Water Tube Boiler1. Larger heating surface can be achieved by using more numbers of water tubes. 2. Due to convectional flow, movement of water is much faster thanWorking Principle of Water Tube BoilerMore and more steam is produced the pressure of the closed system increases which obstructs this convectional flow of water and hence rate productiTypes of Water Tube Boiler1. Horizontal Straight Tube Boiler. 2. Bent Tube Boiler. 3. Cyclone Fired Boiler. 1. Longitudinal Drum Boiler 2. Cross Drum Boiler. 1. Two Drum BenCross Drum Water Tube Boiler1. The feed water is fed to the cross drum through feed water inlet. 2. Then this water comes down through the down-comer pipe and enters into incl Water-Tube Boilers. Water-Tube boiler design is the exact reverse of a fire tube. Here, the water is inside the pipes and the combustion gases move around the outside of the pipes. Water-tube boilers may differ in design; however, their fundamental principles of work are the same.
the tube leaks of firetube boilers in the 1950s. This report recommended the use of a fillet weld on the hot pass of the flues/fire tubes to reduce hoop stress caused by cyclic operations and to provide a heat sink to remove heat stress from the end of the tube extending out from the tube sheet.
Mar 04, 2020· A water tube boiler is such kind of boiler where the water is heated inside tubes and the hot gasses surround them. This is the basic definition of water tube boiler. Actually this boiler is just opposite of fire tube boiler where hot gasses are passed through tubes which are surrounded by water.. Advantages of Water Tube Boiler. There are many advantages of water tube boiler due to which
Engineering Boiler Operation Standard Procedure: The main purpose of the Boiler operation SOP is to ensure that the hotel boiler is maintained in excellent conditions and hot water supply is available to all guest rooms and public areas.. 1) Fill the feed water in the coil with the help of feed water pump till the time water comes out of the by-pass line.
Let’s look closely at these designs in the case of condensing boilers, to have a better understanding of their operation. It should be noted that the design of each individual water-tube and fire-tube condensing boiler also has countless variations and arrangements in order to increase efficiency, response time, capacity just to name a few parameters important to the boiler performance.
Mar 04, 2020· Fire tube boiler is one of the most basic types of boiler and the design is also very old. It was popular in 18 th century. It was mainly used for steam locomotive engines. Operation of Fire Tube Boiler. Operation of fire tube boiler is as simple as its construction. In fire tube boiler, the fuel is burnt inside a furnace.The hot gases produced in the furnace then passes through the fire tubes.
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.
Horizontal Return Tubular Fire Tube Boiler. As one of the oldest and most simple designs for … Package Boiler. Packaged boiler is the most common and efficient type of fire tube boiler used in industry to produce steam and hot water. This boiler delivers to site as a whole package factory assembled. The package boiler only requires electricity, water, steam and fuel connections and it …
