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.

Why Is My Boiler Letting Out Steam? A NJ Tech Explai

Oct 31, 2017· If your boiler pressure levels are over 30 psi (pounds per square inch), your pressure relief valve is letting out steam as a safety measure. You see, your pressure relief valve is designed to prevent your boiler from building up too much pressure and will automatically discharge hot water/steam when pressure levels hit a dangerous level of 30

Raising Steam (Literature) - TV Trop

In Raising Steam, we get to see a relationship between a dwarf and a troll get started. The towns of Zemphis and Ohulan Cutash are mentioned for the first time since Equal Rites, as is the Fiddler's Riddle, although it seems to have improved since Esk was there. Charlie from The Truth makes a …

Residential Steam Boiler Basics - The Spru

The steam boiler is an old convection heating technology dating back over 200 years and is most commonly found in old homes. Because steam boilers operate at a higher temperature than hot-water boilers, they are inherently less efficient than their hot-water cousins and are more finicky to operate.

Boiler Energy Saving Tips | TLV - A Steam Speciali

”Mass of steam produced” refers to the net mass of steam produced by the boiler. This can be found by measuring steam mass flow at the outlet of the boiler, or by subtracting the mass of boiler blowdown from the mass of feed water. As the actual mass of steam generated varies based on the amount of steam required by the plant at a given

Raising steam | The Engineer The Engine

Author: CV-12 Docents Raising steam By Stuart Nathan 1st June 2014 12:00 am 21st September 2017 3:41 pm It’s been about 60 years since steam locomotives ran as part of the UK’s regular scheduled rail service, but steam trains still hold a special place in the hearts of many.

Steam Boilers v Steam Generators: The Differences | Ne

This increased water content also enables steam boilers to respond to varying steam loads, an advantage that usually outweighs the longer cold start-up time associated with steam generators. Additionally, during normal operation, burner firing on a steam boiler is also achieved quickly as no water purging is required.

High-pressure steam locomotive - Wikiped

The reason for high pressure. Maximising the efficiency of a heat engine depends fundamentally upon getting the temperature at which heat is accepted (i.e. raising steam in the boiler) as far as possible from the temperature at which it is rejected (i.e. the steam when it leaves the cylinder).This was quantified by Nicolas Léonard Sadi Carnot.. There are two options: raise the acceptance

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.

Safe boiler operation - Preparations & raising ste

Safe Boiler operation - Preparations & Raising steam Marine boiler working preparations: A boiler is used to heat feed water in order to produce steam. The energy released by the burning fuel in the boiler furnace is stored (as temperature and pressure) in the steam produced.
