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 Operation and Maintenan

For all steam boilers, this should be done annually. Hot-water boilers present special problems when doing a low-water fuel cutoff slow drain test. For hot-water boilers, the slow drain test should be done annually but only if this can be done without draining the entire system and without draining considerable quantity of water from the boiler.

Marine Boilers Oil Contamination – Officer of the Wat

Oct 25, 2012· Oil contamination on boilers should lead to the rectification of the heat-transfer surfaces on the water and steam side prior to the boiler being put back into service. Boiling out the water side of the boiler using recommended chemicals and/or mechanical cleaning are normal procedures undertaken to facilitate satisfactory cleaning.

OBSERVING BOILER SAFETY RULES - idc-online.c

k. Water And Steam Systems Ø Visual survey all the areas of the plant to check for damage and ensure no unauthorized persons tampered with the plant. Ø Do NOT refill a boiler while it is hot. Treated warm water should be used. The boiler should be vented to permit air to escape. Ø Check the water level in the gauge glass (mid point) and all the gauge

Open the main steam-stop valve(s). When the pressure reaches 10 to 15 psig, close the boiler vent. Test the low-water cutoff by securing the boiler feed and let the boiler steam off naturally to see if the switch cuts power to the burner at the proper low level.  If it does not, break power to the burner immediately and take corrective action.

Precautions for Cleaning Water-tube Boile

File Size: 1MB IV. Procedures Soot blowers, if available, should be blown before the boiler is removed from service. Valves to interconnecting systems (such as steam, blow-off and feedwater) should be fully closed, locked, tagged and common piping connections blanked. If the boiler is in battery with operating boilers, the blow-off valves on the operating

[PPT]· Web viewTry cocks are used to determine the boiler water level if the gauge glass is not functional. 2-All steam boilers must have two methods of determining the water level in the boiler. The gauge glass is the first and easiest method for determining boiler water level. A second method for determining boiler water level is try cocks. Try cocks

Getting to the Bottom of the Boiler Blowdown Procedu

Contact Us · Article Library Nov 08, 2016· The boiler blowdown procedure is the purposeful discharge of water from the boiler. This practice works to avoid the build-up of concentrated impurities inside of the system. These byproducts and impurities are the result of the continual evaporation of steam.

Chapter 14 Boilers - Pearson Educati

removing small amounts of water from the boiler to reduce the concentration of impurities. Blowdown can be either continuous or intermittent. Continuous blowdown is the constant removal of a small quantity of boiler water from the steam drum to remove suspended solids and salts that could concentrate in the steam drum.

There are carbon filters, multilayered filters, sand or iron filters. There can be lined tanks, AsME code tanks and automatic operation based on a time clock, pressure differential switch or water meter. They can protect such items as water softeners, dealkalizers, and reverse osmosis equipment, etc.

Boiler Operation & Boiler Maintenance | HSB Locomoti

File Size: 308KB The importance of proper cleaning and maintenance of the water gage glass, or sight glass, cannot be stressed enough. The gage glass on a steam boiler enables the operator to visually observe and verify the actual water level in the boiler. But water stains and clogged connections can result in false readings. The glass also may break or leak.
