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.
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 Steam Drum Level While designs and sizes vary, most subcritical boilers have a drum at the highest point where steam is collected and the tubes come together. Maintaining the right water
Click to view2:04Oct 31, 2018· Today on Boiler University's Weekly Boiler Tips, watch as Jude talks about knowing the water level in the boilers sight glass. Having water in the boiler is incredibly important so knowing how to
Natural circulation is caused by the density difference between saturated water and heated water partially filled with steam bubbles. In a natural circulation unit the water tubes are connected to a loop, Fig. 4.3.Heat is applied to one leg, called the raiser tube, where the water–steam mixture flows upward.
What is a downcomer in a boiler?Aug 03, 2018If the ph of a boiler feed water is at a range of 8.5-9.5May 07, 2018What is boiler water PH? And why so maintained?Jan 26, 2018What is the difference between DM water and boiler feed See more results Water level indication and boiler water levels. Water level indication applies to steam boilers where the water level can be detected. It includesmost steam boilers, the exception being those of the ‘once through’ or coil type, where there is no steam drum.
Aug 06, 2018· Chemical reactions happen very fast at elevated temperatures. Because of this we try to operate the boiler at the lowest possible corrosivity relative to pH (Note: this is only for boiler operating without high purity feedwater). That point is aro
Aug 29, 2017· Drum water filling is a very important activity before boiler light up . in boiler hydrostatic test we also filling the drum with above method but in this condition little bit variation in the process of water filling . first of all insure that the suitable D.M water level is available in deaerator after that check out healthyness of the boiler feed pump . before start up of the boiler feed
The boiler drum process is a nonlinear, complex and multivariable process which includes significant time delay. Therefore, the control on the water level in the drum is not easy and ideal.
A steam drum is a pressure chamber of a steam boiler located at the upper extremity of steam boiler circulatory system. It is a reservoir of water/steam at the top end of the water tubes. The steam drum stores the steam generated in the water tubes and acts as a phase-separator for the steam/water mixture.Steam is separated from the water and then discharged at a position above the water level
Author: wareboilers At the heart of any steam generation system is the boiler/steam drum. Although it comes in many sizes, its primary and peripheral functions are as follows: providing ample surface area for the efficient separation of water and steam; providing storage capacity to meet immediate boiler feed water requirements; and facilitating the introduction of chemicals for treatment purposes, as well as the
After having the common safety measures to make certain that the boiler and location are cleared of personnel, close the boiler (with the exception the drum vent) and also close all access and inspection doors. Get rid of a manhole on the steam drum and fill up the boiler till water shows up in the drum.
