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.

Condensing, Extraction and Inducti

Condensing, Extraction and Induction Turbine by removing the cover only and the base need not be disturbed after instal­ lat ion. This turbine has no bedplate. The cylinder is rigidly s>upported and anchored at the exhaust end by two pads which are either cast inte­ grally with or bolted rigidly to the base.

Turbine Trip and Turbine Water Induction - CR4 Discussi

Jun 26, 2012· Re: Turbine Trip and Turbine Water Induction 06/26/2012 1:04 PM First "water induction": In a steam turbine, unless the turbine is designed to operate with liquid water mixed with the steam, the turbine may be seriously damaged when the dense, liquid water strikes the rotor buckets (blades).

Isolation of mechanical equipment Flashcards | Quizl

A "closed drain" is a) a drain line with a single isolating valve b) a drain which has been blanked off by a blind flange c) any drain where the effluent is not considered to be harmful to life, property, or the environment d) defined as any drain line left normally in the closed position e) a drain line having two isolating valves in the line

Chaplin ©Encyclopedia of Life Support Systems (EOLSS) The flow of high pressure steam entering the turbine is controlled by governor valves and stop valves.The former control the flow to ensure that the appropriate amount of


PUMPS AS TURBINES (PAT'S) Robert Honders of New York is a member of the micro-hydro forum on Yahoo. He has a small micro-hydro installation that consists of a pump with a directly coupled induction motor that is run in reverse to act as a turbine.

US3774394A - Gas turbine engine fuel drain system a

A fuel drain system for an aircraft gas turbine engine includes an eductor pump and valve means therefor to direct both fuel pressurized by the engine during engine spin-down and fuel drained from the fuel supply system upon engine shutoff to the eductor so as to recycle the latter to a point in the fuel supply system which is upstream of the fuel supply system shutoff valve.

Impacts of cycling - turbine water induction even

File Size: 310KB Oct 05, 2015· While identification and training to respond to water induction is important, preventing water induction is the preferred strategy. A proactive defense scheme involves a means of detecting water before it enters the turbine, procedures to isolate and remove any accumulated water, and, most importantly, the systems that prevent water induction

Extraction Steam/Heater Drain (ES/HD) Flashcards | Quizl

b. Prevents water from entering turbine in the event of tube rupture or flooding of heaters. A High-2 level in a feedwater heater will trip the NRCV shut to prevent water backing up to turbines. 2. In MSR drain tank lines: Prevents reverse flow from #17 and #15 heaters and Heater Drain Tank to MSR drain tanks only during turbine trip. 3.

Replacement Instruments Improve Turbine Water Inducti

Turbine water induction protection systems are designed to keep water out of the turbine and prevent damage. Steam turbine damage from water induction is a costly economic, safety, and reliability

What is turbine drain valve - Answe

When steam is introduced to a turbine during start up, drain valves are fully open. They drain to the condenser until the turbine reaches a certain load. Once that load is reached, the valves are
