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.
Since the entropy of dry saturated steam at 0.04 bar a (8.473 kJ/kg °C) is greater than the entropy of the superheated steam at 50 bar a/300 °C (6.212 kJ/kg °C), it follows that some of the dry saturated steam must have condensed to maintain the constant entropy.
Jan 08, 2019· The saturated steam drawn from a boiler is passed through a detached heating device which transfers extra heat to the steam by contact or by radiation. Superheated steam is not usually used in a heat exchanger due to low heat transfer coefficient.
Aug 02, 1970· Superheated steam is often required for process reasons or in applications where the steam will be used in a steam turbine. This need for superheated steam is thus specified by the steam user rather than the boiler designer. The superheater is added upstream in …
Steam is water in the gas phase. It is commonly formed by boiling or evaporating water. Steam that is saturated or superheated is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapour condenses.. The enthalpy of vaporization is the energy required to turn water into the gaseous form when it increases in volume by 1,700 times
What are some of the most unsaturated markets in 2019?Jul 05, 2019What is a saturated and unsaturated reactance in a 3-phaseMar 18, 2019What is saturated steam?Jan 05, 2019What is the difference between saturated steam and superOct 27, 2016See more results Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.
In a boiler, energy from the fuel is transferred to liquid water in order to create steam. Once the water is heated to boiling point, it is vaporized and turned into saturated steam. When saturated steam is heated above boiling point, dry steam is created and all traces of …
Form this super-heater header steam enters into another pipe called superheater element pipes. It is the place where saturated steam becomes superheated. Then superheated steam enters into the steam pipe of the smoke box. Related: Construction and Working Principle of Cornish Boiler. When saturated steam becomes superheated then it goes to the
Mar 04, 2020· Superheated Steam When saturated steam generated in steam boiler is further passed through a heat transfer surfaces, then its temperature will starts increasing above evaporation or saturation. Steam is described as super heated, if its temperature is more than that of its saturation temperature. Degree of super-heat is directly related…
Author: Fair Weather Foundry Steam Superheaters in Industrial Boilers. The Steam Superheater is a coil type heat exchanger which is used to produce superheated steam or to convert the wet steam to dry steam, generated by a boiler.. It is different from a boiler in a way that, boiler utilizes both sensible heat as well as latent heat to convert water into steam while superheater utilizes only sensible heat to superheat the
May 02, 2020· The heat from this gas is transferred to Saturated Steam in the superheater pipe, so it turns into superheated steam. Working & Components of superheater: This superheater has two parts, the primary superheater and the secondary heater. The primary superheater is the first heater that is passed by steam after the steam comes out of the steam drum.

The super-heater is placed in the radiation chamber and is normally not equipped with water injection for controlling the superheating of the steam. The boiler is ideal for producing electricity as an add-on to saturated process steam.
