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 Combustion Air Flow Measurement | Yokogawa Ameri

How Is Boiler Air Flow Measured? Boiler air flow (or air flow on a forced or balanced draft furnace) may be measured with a pitot tube, air foil section, or any calibrated flow restricting device located in the duct that leads from the forced draft fan to the windbox. (The windbox is the area behind the burner throats that supplies combustion

10 Common Boiler Formulas STATIC HEAD PRESSURE What is the static head pressure of a boiler operating at 275 psi? SHP = Bpr * 2.31 SHP = Bpr * 2.31 SHP = 275 * 2.31 SHP = 635.25 Where, SHP static head pressure Bpr boiler pressure (psi) 2.31 multiplier STEAM PRODUCED How much steam will a 150HP boiler make in 2.5 hours? S = HP * 34.5 * T

Jun 19, 2012· The outside air sensor can be wired directly to the boiler master controller or reset logic can reside in the BAS with a supply water temperature setpoint output to the boiler master controller. The range of reset schedule should be selected to coincide with the operating conditions of the condensing and noncondensing boiler operations.

Combustion Air Flow and Differential Pressu

File Size: 1MB Not only is it used to prove things like air or water flow, but we also use it to measure flow. Put a know restriction in a pipe with flow.which creates a pressure drop, add an differential flow transmitter like the Honeywell STD900 or STD3000 and you have a very accurate method of measuring flow.
