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.

Problems in Boilers – Marine Stu

May 22, 2015· Image Credit:www.globalspec.com Some common boiler problems are described below: Fires Cleanliness of the heat recovery surfaces after the boiler can often be judged by observing the gas pressure differential above and below. Any significant rise in this value should be attended to. Whilst good combustion conditions will minimise the risk, deposits allowed to accumulate in this area are a

Advantages and Disadvantages of Water Tube Boilers ov

Advantages and Disadvantages of Water Tube Boilers over Fire Tube Boilers: Advantages: 1. Steam can be raised more quickly: In water tube boilers, the ratio of water content to the steam capacity is comparatively less than the fire tube boiler. Hence water tube boilers can quickly generate steam at the required pressure than the fire tube boiler. 2. Steam at higher pressures can be produced

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 Burners for Water Tube, Fire Tube, Firebox Boile

For commercial watertube and firetube boilers in BTU ranges from 1,674,000 BTU/hr thru 17,000,000 BTU/hr, requiring low NOx levels, high combustion efficiency, and high turndown, our JBS product line is a perfect fit. The JBS is also effective in highly engineered applications requiring alternative fuels and multiple fuel curves.

maintenance procedures of the boiler oil burning equipme

possibilities of using natural biogases to fuel fire tube boilers; Per the state's fire marshal guidelines, inspections are required at one-, two- or three-year intervals, depending on the type of equipment. Low-pressure boilers typically used for heating and supplying potable hot water are inspected every two years.

Boiler Types and Classifications - Wiki - odesie by Te

The most common fire-tube boilers used in facility heating applications are often referred to as ''scotch'' or ''scotch marine'' boilers, as this boiler type was commonly used for marine service because of its compact size (fire-box integral with boiler section). The name "fire-tube" is very descriptive.

Fire Tube Boiler - Construction, Types and Its Worki

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.
