Introduction of WNS gas / oil fired steam boiler:

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.

Technical advantages:

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.

Types of boilers, Fire tube, water tube and combinati

May 02, 2020· 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. As a guideline, competitive fire tube boilers for steam speeds up to 12,000 kg / hour with pressures up to 18

What is difference between water tube boiler and fire tu

May 04, 2017· Water Tube Boiler: * Water circulates in tubes and heated externally by hot gases. Fuel is burned inside the furnace. i.e (hot gases- outside the tubes and water- inside the tubes). * Operating pressure = upto 100 bar * Efficiency = upto 90% * Ste

Comparison Between Fire Tube and Water Tube Boil

Jun 05, 2018· Comparison between Fire Tube and Water Tube Boiler can be done in 14 aspects. Those aspects are operating pressure, passage of material type in tubes, rate of steam generation, handling of load fluctuation, floor area requirement, efficiency, operator skills, design, maintenance cost are listed below in the tabular form.

Water Tube Boilers vs. Fire Tube Boilers - Miura Boil

Why Miura Water Tube Boilers Are More Efficient Than Traditional Fire Tube Boilers. When choosing a steam boiler for your facility, you typically have a choice between a water tube or a fire tube design.While both may have their advantages in certain situations, from an efficiency standpoint, Miura water tube boilers are far more efficient than fire tube boilers.

Water Tube Boiler Parts and Functions - Boilersin

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.

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 We briefly discuss about Water tube boiler parts and functions. D type water tube boiler. In the water tube boiler, the water and steam flow inside the tubes and the hot gases flow over the outside surfaces. Where as in fire tube boilers hot gases from combustion travels through the tubes. flue gases produced from furnace where fuel is burnt.

Difference between Fire Tube Boiler and Water Tube Boil

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 …

Choosing The Right Boiler: Watertube vs. Firetube - Boil

Author: MECH LEARN Jun 13, 2013· From a cold start, the firetube boiler, due to its larger water volume, takes longer to bring up to operating temperature or pressure vs. a similar sized watertube boiler. With less water volume, a watertube boiler can follow load swings more precisely and generally has better turndown.

Fire-tube boiler - Wikiped

A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.. The fire-tube boiler developed as the third of the four major historical types of boilers: low

Water Tube Boiler – Working Principle, Types of Water Tu

A water tube boiler can be defined as a Steam boiler in which the flow of water in the tubes, as well as hot gases, enclose the tubes. Not like fire tube boilers, this boiler attains high-pressures, as well as high-steam capabilities, can be achieved.
