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 Low- and High-Pressure Boilers | Hunk

A boiler is an appliance designed to heat water and produce energy. The heat is applied to water in an enclosed container before being distributed throughout the system. The major difference between a low-pressure and a high-pressure boiler is the amount of pressure per square inch and pounds per square inch gauge that the boiler produces.

Cleaver-Brooks | Reference Center | Boiler Basics | Ste

Steam boilers are designed for low-pressure or high-pressure applications. Low-pressure boilers are limited to 15 psig design, and are typically used for heating applications. High-pressure boilers are typically used for process loads and can have an operating pressure of 16 to more than 1,000 psig. Most steam boiler systems require saturated

High Pressure Boilers | Powertherm | Manufacturer | Wat

High Pressure Boiler | Water Tube Boiler High Pressure Boilers Working. Before converting to steam, water circulates multiple times from shell (water drum) to water tubes and then back to shell.During the circulation, the temperature of water increases as it comes in indirect contact with flue gases that transfer heat through tubes.

High pressure boilers - LinkedIn SlideSha

Feb 02, 2016· 1. La Mont boiler • It is high pressure, water type boiler • The water circulation is maintained by centrifugal pump. • La Mont boiler generates approximately 45 to 50 tonnes of steam per hour at a pressure of 13 bar and a temperature of 500°C. Advantages of a La Mont Boiler: 1.

Lower Pressure Operation of Boiler than Design

In constant pressure operation the boiler superheater outlet pressure is designed to be maintained constant from as low as 40% of the rated maximum continuous load. In sliding pressure boilers the superheater steam outlet pressure is slowly taken up at a particular ramping rate acceptable to both boiler and turbine designers.

What do you mean by working pressure of a boiler? - Quo

Working pressure is the same thing as the maximum allowable working pressure or MAWP. The two terms are used interchangeably. Per the link below - MAWP is the maximum pressure at which the vessel or equipment is allowed to function at a specif

Volume 1, Steam Boilers - Steam, Heating Hot Water, a

1.3.2 The boiler system shall be capable of supplying the maximum demand with the largest boiler no t operating, and with the largest pump of each service not operating. 1.4 Boiler header pressure: 1.4.1 Boiler Header pressure shall be sufficient to serve the pressure requirements of the loads in an economical manner.

Boiler Pressure - an overview | ScienceDirect Topi

Boiler pressure is the key factor for determining the need for a condensate polishing system. With a steam generator plant with low steam pressures (below 40 kg/cm 2), the requirement of the CPU is usually avoided.Hard scale formation and boiler metal corrosion can easily be prevented through FW treatment before sending to the boiler proper.

Design Pressure vs Operating Pressure - Boiler a

So if you had set the design pressure of the vessel at say 7 bar, then you now need full flow pressure relief to ensure the pressure in the vessel doesn't exceed the design pressure or MAWP. This can be very onerous, so the alternative is to set the deign pressure to say 12 bar.

Types of High Pressure Boilers | Scienci

The (normal) operating pressure and the design pressure are defined in 3-2 by the code (Div.1). The operating pressure has no practical influence oThank you prex What do you mean by "eventual pressure surge"? Is it occasional pressure surge? Warm RegardsNice philosophical question to start the week. "What is the basis for defining design pressure for an equipment? " "Is there any sensible relat@LittleInch Thank you very much for your detailed response. The equipment that I mentioned with zero barg operating pressure were actually someLittleInch, When you are calculating MAWP, do you need take into account nozzle loads applied to your pressure vessel's nozzles? I think, you neecurtis2004, you do not take nozzle loads into account for calculating MAWP. Instead, you ask nozzle designed to be good for MAWP+ external loads.Design temperature of pressure vesselsMar 01, 2007Design Life for Pressure Vessel See more results Types of High Pressure Boilers. A boiler is a vessel in which water is heated under pressure and vaporized into steam for a specific purpose. There are several different kinds of boilers, heated by coal, solid fuel, oil or gas. Boilers vary widely in size from small, portable or shop-assembled units to …

Boiler Design: Composition, Benefits, & How to Sta

A Steam boiler is a steel pressure container in which water under pressure is transformed into steam by the use of combustion. In other words, the boiler is just a heat exchanger which uses radiant heat and hot flue fumes, released from burning fuel, to produce vapor and hot water for heating and processing loads.
