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.

Different Types of Valves in the Boiler Room - Boiling Poi

Aug 20, 2018· Today on the Boiling Point, Ritchie talks with Brian Grinestaff about the different types of valves that you may find in your boiler room. Valves will normally fall into two different groups

Paper Processing Industry Boil

Paper Processing Industry Boiler. Capacity 0.1~220t/h; Available Fuel coal, biomass fuel, oil, gas, electric, etc.; Heating Medium steam, hot water, thermal oil, hot air; Brief Intro In paper processing industry, steam is generally used for drying to improve the strength and smoothness of paper, and it also used for hot pressing, strewing, concentration, etc. Sitong boiler could customize the

Water pressure release valve on my boiler is leaki

Dec 13, 2010· The valves fill up with crap. If it is the pressure release valve - then it's there in case the water in the boiler goes over pressure - it will open and release water. So - if the thing is leaking - then it is unlikely that you are going to have a problem with the boiler running out of water - because there is obviously water in the system.

Characteristics of boiler feedwater - Lennte

Feed-water purity requirements therefore can vary widely. A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers. Only relatively wide ranges can be given as to maximum levels of alkalis, salt, silica

Control valves reduce boiler feedwater pump proble

Control valves reduce boiler feedwater pump problems. Southwestern Public Service Co.`s (SPS) Harrington Station in Amarillo, Texas, switched to high gain control valves applied in series for an

Valve styles that can handle everything from abrasive Kaolin clay slurries to recycle trash. The application guide charts on

Different Types Of Valves Use in Boiler - Maintenan

Different types of valves we use in boiler room here are some example. Ball valve; Gate valve; Globe valve; Check valve; All these valves have the application in the purpose for controlling and isolation or creating backflow on a process.

Plant Engineering | Troubleshooting boiler operati

Generally orifice pipes are more reliable and economical. At a boiler load below 25% to 40%, the feedwater pump will be operating on the “flat part of the curve.” An ARC valve is simply not accurate enough to detect a minimum pressure differential change of possibly 1 to 2 psig when the “drum level-control-valve” closes.

Boiler Fill Valves & Makeup Water Valves - PexUniver

Most boiler fill valves are similar in design and specs (but could use different quality of materials - hence the price difference), and have a 10-25 psi adjustable outlet pressure, often factory set to 12 or 15 psi. They are simply pressure reducing valves designed for boiler feeding applications. Some models may utilize a built-in check valve.
