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.

Difference Between Fire Tube Boiler and Water Tube Boil

Fire-tube boiler: Fire-tube boiler is those boiler in which the fire or hot gas is present inside the tubes and water surrounds these fire tubes. Since fire is inside the tubes and hence it is named as fire tube boiler. The heat from the hot gases is conducted through the walls of the tube to the water.

Fire Tube Boiler | Operation and Types of Fire Tube Boil

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.

Boiler Deaerator Working Principle - Boilersin

In the Boiler deaerator Working Principle Water is heated close to saturation temperature with a minimum pressure drop and minimum vent. This ensures the best thermal operating efficiency. Deaeration is done by spraying the boiler feed water over multiple layers of trays designed to provide large contact area of the liquid surface to Pegging steam.

Water-tube boiler parts and Working Princip

Water Tube Boiler Working Principle: To understand the water tube boiler working principle, we will discuss the simple above water tube boiler diagram. This boiler consists of a steam drum (Upper Drum) and a mud drum (Lower Drum). Feedwater with the help of a feedwater pump enters the steam drum.
