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.

How to size a boiler-feed pump | 2016-08-30 | Plumbing a

Aug 30, 2016· When it comes to boiler-feed pumps, the two important variables are the amount of water in the operating range of the boiler and the steam-to-condensate time lag across the system. The operating range is the vertical distance between the center of the gauge glass and the low-water cutoff point. It’s not something manufacturers usually publish in their literature, but if you ask, they’ll be

Boiler feed pumps are also referred to as feed pumps (see Reactor pump) and designed as multistage radial flow pumps. (Also see Multistage pump.) They serve to feed a steam generator such as a boiler or a nuclear reactor with a quantity of feed water corresponding to the quantity of steam emitted. Today, all boiler feed pumps are centrifugal pumps. The design of boiler feed pumps regarding

Boiler Feed Water Pump Working Principle and Operati

Two Aspects of Deciding Between A Ring-Section and A Barrel Pull-Out Pump Are Described Below1. The smaller the mass flow rate and the higher the pressure, the higher the material and manufacturing costs of barrel pull-out pumps. This doesTapping A Stage of A Boiler Feed Pump1. In the case of ring-section pumps, a partial flow at an intermediate pressure can easily be tapped through a tapping nozzle in one of the stageBalancing of Radial Forces on The Pump RotorRadial forces arise from the weight of the rotor, mechanical unbalance or hydraulic radial thrust. The radial forces are balanced by two oil-lubricWarming Up and Keeping WarmTransient or low flow operating conditions cause additional loads on boiler feed pumps. This leads to additional stresses and strains as well as to Boiler feed water pumps are commonly centrifugal pumps. To ensure a high enough head and pressure, Boiler feed Pumps have been arranged in series (multistage pumps). A feedwater pump is most often driven by an electric motor for energy efficiency. Often two steam turbine-driven (turbo pump) and two electric feedwater pumps are used.
