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.
Aug 30, 2018· Coal that has been ground into a fine powder by a pulverizer is blown into a furnace-like device, called a boiler, and burned. The heat produced converts water, which runs through a series of pipes in the boiler, to steam. The high-pressure steam turns the blades of a turbine, which is connected by a shaft to a generator.
Mar 09, 2017· The coal fires within each furnace would bring the water inside the boilers to a temperature of almost 400° F with steam pressure reaching 215 psi. With this pressure reading the steam was channeled to the reciprocating engine room through a network of well insulated conduit.
How was coal fed into ship's boilers?May 15, 2019Where did the water come from to run the boilers on Titanic?Jun 19, 2018How did steamboat pilots communicate with the boiler roomJul 01, 2017Which was better, oil-fired battleships or coal-fired See more results A boiler is water containing vessel which transfers heat from a fuel source (oil, gas, coal) into steam which is piped to a point where it can be used to run production …
Apr 09, 2018· As the coal is initially milled to a fine powder to be pulverized and then burnt in a furnace (combustion chamber of a boiler); and we use the heat energy released to heat water into super-hot steam which under high pressure and temperature used to turn the turbines connected to electrical generators by a shaft which then drive the generators to produce electricity.
Oregon Apprenticeship Guide - Boiler Operator & Repairer Job Description Boiler operators run automatically fired boilers to generate steam for buildings or industrial plants. The work includes feeding fuel into furnaces or boilers, observing pressure, temperature and draft meters on panels to verify specified boiler fuel feed, draft openings, water level and steam pressure.
Inside the Boardman Coal Plant. Chapter three. How it works. The burner is part of a boiler 20 stories high, hanging from the ceiling. Trump EPA rolls back Obama rule on coal-fired power
The Combustion system converts energy in coal to Heat. Water and steam system converts the heat to steam at high pressures and temperatures. This series explains the working of the boiler …
Evapotranspiration and the Water CycleNov 06, 2019Hydroelectric Power: How it WorksAug 30, 2018Thermoelectric Power Water UseAug 30, 2018See more results Coal contains moisture. Hot air form the Primary Air Fans dry the coal in the pulverisers. This makes the burning easy and efficient. This air also carries the dry coal powder from the pulverisers to the burners in the boiler furnace.In the burners the coal powder is mixed with the required amount of Combustion air and burned in the furnace.
As an example consider these facts for typical coal fired power plant of capacity 500 MW. Around 2 million tons of coal will be required each year to produce the continuous power. Coal combustion in the boiler requires air. Around 1.6 million cubic meter of air in …
