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 and Condenser Pressures - Rankine Cyc

The thermal power plants are currently designed to operate on the supercritical Rankine cycle (i.e. with steam pressures exceeding the critical pressure of water 22.1 MPa, and turbine inlet temperatures exceeding 600 °C). Supercritical fossil fuel power plants, that are operated at supercritical pressure, have efficiencies around 43%.

What is the temperature of a boiler in a power plant? - Quo

If a power plant has both CFBC and WHRB boiler operating for same TG then there furnace temperature will have similar range of temperature.So we can't generalise a certain temperature for CFBC or WHRB boiler or any other boiler.In some cases it' s temperature range varies from 850 to 950 degree centigrade.

Types of Boilers Used in Power Plants--Z

Steam Superheater in Boiler: Role, Benefits, Typ

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

World’s Largest Circulating Fluidized Bed Boiler Begi

At the heart of the 460-MW plant is the world’s largest CFB boiler, which is also the world’s first once-through unit (OTU) supercritical CFB boiler. The Å agisza plant (Figure 1), owned by

Industrial High Pressure Boiler-ZBG Boil

High-pressure boiler means a boiler operating at a steam or other vapor pressure of over 9.8MPa. It is generally used in power plant, our high pressure boilers used for power generation have capacities of 4 to 400 tonnes/hr of superheated steam with a pressure up to 13.7MPa and a temperature …

Firetube Boilers - National Board of Boiler and Pressu

Each ASME BPV Code Section I high-temperature water boiler must have: A pressure gage (PG-60.6). A temperature gage (PG-60.6.4). Although not referenced in ASME BPV Code Section I, there should be some means of controlling temperature. This will vary with the size and complexity of the boiler. A means of adding water to the boiler while under

Auxiliary Boiler - an overview | ScienceDirect Topi

Wilfrid Francis, Martin C. Peters, in Fuels and Fuel Technology (Second Edition), 1980. Publisher Summary. This chapter provides an overview of boiler auxiliaries. The following boiler auxiliaries are required by the British Boiler Regulations: (1) safety valves, (2) water gauges, (3) boiler feed check valve, (4) blow-down valve, (5) low-water-level safety device, and (6) main stop valve.

What is the temperature of a boiler in a power plant

Nov 04, 2017· In steam, temperature and pressure are related up to the point superheat is added. Steam pressures could be anywhere from 450 PSIG to over 2,000 PSIG with varying degrees of superheat and yet put out the same power in the end.

Understanding A Hot-Water Boiler - DIY in a ho

In a three part gauge, the moving pointer shows actual pressure; the fixed pointer shows minimum pressure. If the moving pointer drops below the minimum, the system needs water. The lower temperature gauge shows water temperature. Maximum boiler water temperature is set by moving a pointer along the sliding scale of an aquastat.

What is the maximum moisture content of steam at t

I have a boiler operating at 5bar and produces saturated steam. From steam tables, the temperature is 151.9 degrees Celcius. I have tried using the continuity equation but …
