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.

Steam Boilers - The Inside Story: Part 8 - TDS Contr

File Size: 1MB Mar 13, 2014· Part 8 of 9: Whenever a boiler produces steam, dissolved solids occur which can adversely affect the quality of the steam produced. This video …

Steam Boiler Water Dissolved Solids, TDS Contr

As steam is evaporated the concentration of total dissolved solids (TDS) increases in the boiler water. If the TDS concentration is allowed to get too high then carryover of boiler water will occur. This carryover can cause serious damage to the steam and condensate systems through corrosion and deposition on heat transfer surfaces.

Boiler Water Treatment Part 2 – Internal Treatme

Boiler Water Treatment Part 2 – Internal Treatment Objectives of Internal Water Treatment 1 – To control the level of total dissolved solids (TDS) within the boiler As water is boiled within the boiler and steam is produced, then the solids remain in the water and concentrate. Thus, over time the level of total dissolved solids (TDS) increases.

Total Dissolved Solids - T

TDS = 1.1 10 6 (ρ - 1) (1) where. TDS = Total Dissolved Solids (ppm) ρ = relative density of the boiler water at 15.5 o C. This is a manual method requiring measuring a cooled down sample with a very sensitive hydrometer. Measuring TDS with the conductivity method. TDS = 0.7 σ (2) where

Accurate boiler blowdown - Plant & Works Engineeri

Automatic TDS control measures the actual TDS level and water is drawn off the boiler continuously, but at a varying rate to maintain a steady TDS level. This is the most efficient way to control your blowdown and will save much energy. Bottom blowdown is also best controlled automatically.

Controlling TDS in the Boiler Water | Spirax Sar

By installing an automatic TDS control system the average boiler water TDS can be maintained at a level almost equal to the maximum allowable TDS as shown in Figure 3.12.9; Evaluating savings by reducing blowdown rate. If a boiler is to supply a given amount of steam, …

Boiler Water Treatment | Sensors for Process Contr

File Size: 305KB A boiler is a closed vessel where water under pressure is transformed into steam by the application of heat. This process is useful for a variety of industries, from industrial and manufacturing environments to food and beverage processing. In the boiler furnace, the chemical energy in …

Steam boiler scale inhibitor, sludge (TSS) and TDS contr

Author: IndiaMART Sellers - Electronics & Machines Dec 11, 2003· The steam boiler scale inhibitor, sludge (TSS) and Total Dissolved Solids (TDS) control, and automatic bottom blow-down management system according to claim 1, wherein water is admitted back into the bottom outlet port through a smaller return tube that is built inside the boiler drum outlet port connector, said return tube further comprising a

Boiler Blowdown - Fact She

File Size: 784KB control the concentrations of suspended and total dissolved solids in the boiler. Surface water blowdown is often done continuously to reduce the level of dissolved solids, and bottom blowdown is performed periodically to remove sludge from the bottom of the boiler. …
