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.

Boiler (power generation) - Wikiped

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Classifications of Boilers - Engineering ToolB

According the "ASME Boiler and Pressure Vessel Code" boilers may be classified asSection I Power Boilers - process boilers, power boilers and high pressure boilers. boilers in which steam or other vapor is generated at a pressures exceeding 15 psig ; high temperature water boilers intended for operation at pressures exceeding 160 psig and or temperatures exceeding 250 degrees F

Boiler Terms - Boiler Glossary - P C McKenzie Compa

A. Absolute pressure – The pressure above zero pressure, equal; to gauge pressure plus atmospheric pressure.. Acid cleaning – The process of cleaning the interior surfaces of steam-generating units by filling the unit with a dilute acid accompanied by an inhibitor to prevent corrosion and by subsequently draining, washing, and neutralizing the acid by a further wash of alkaline water.

Boiler - definition of boiler by The Free Dictiona

Define boiler. boiler synonyms, boiler pronunciation, boiler translation, English dictionary definition of boiler. boiler water-tube boiler n. 1. An enclosed vessel in which water is heated and circulated, either as hot water or as steam, for heating or power.

Steam Boiler - Definition, Working Principle, Types, a

Author: Julia Kagan Generally, a steam boiler is a type of closed container, designed with steel for heating the water to generate steam by some energy source like burning of fuel with eventually. The vapor generated may be delivered at low-pressure for the industrial progression work in sugar industries, cotton mills, and for generating steaming water that can be utilized for heat up fixing at much low-force.

Boiler Operation & Boiler Maintenance | HSB Locomoti

Boiler logs are the best method to assure a boiler is receiving the required attention and provide a continuous record of the boiler's operation, maintenance and testing. Because a boiler's operating conditions change slowly over time, a log is the best way to …

Corrosionpedia - What is a Boiler? - Definition fr

Jul 03, 2018· A boiler is an energy conversion or transfer system where chemical energy from fuel is converted into either heat or electrical energy. It consists of a tank or a closed vessel in which liquid is stored and heated using hot gases generated from the combustion of fuels such as coal, fuel oil or natural gas that burn in a furnace, or from electrical coils.

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.

Chapter 10 Boiler Feedwater Deaeration | SU

In order to deaerate the boiler feedwater, water is sprayed into a steam atmosphere. This heats the water to within a few degrees of the temperature of the saturated steam. Because the solubility of oxygen in water is very low under these conditions, 97 to 98% of the oxygen in the incoming water is released to the steam and is purged from the

What is Boiler ? | Components & Application | Thermody

What is a boiler? Boilers are defined as “Boiler is a closed vessel in which water or other liquid is heated, steam or vapor is generated, steam is super-heated, or any combination thereof, under pressure or vacuum, for use external to itself, by the direct application of energy from the combustion of fuels, from electricity or nuclear energy.. The boiler is a primary part of global heating
