high pressure waste heat boiler - Bing 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 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.
Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
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.
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.
· PDF fileWaste heat is a valuable resource. Johnston Boiler Company’s line of single and triple pass Waste Heat Recovery (WHR) boilers offer your company a way to save valuable energy, energy typically lost in waste heat. The WHR se-ries are used in petrochemical plants, refineries, steel mills, ore converters, brick or cement plants, glass works, and
For waste-heat boilers and economizers, the tube material is normally carbon steel. If the heat is recovered from process gases containing hydrogen, it is important, particularly at high steam-pressure levels, to check the tube material for hydrogen embrittlement using ref.2, in which case a molybdenum or low-chrome steel may be necessary.
Thermal Design of Economizer for Waste Heat Recovery . 2019-7-1 · Waste heat recovery boiler uses waste flue gases for steam production, so this economizer is also work on these varying parameters like gas flow rate, temperature variation, pressure variation, amount of ash content in flue gases.
Types of High Pressure Boilers. A boiler is a vessel in which water is heated under pressure and vaporized into steam for a specific purpose. There are several different kinds of boilers, heated by coal, solid fuel, oil or gas. Boilers vary widely in size from small, portable or shop-assembled units to …
JUMAG waste heat boilers utilise hot flue gases from an upstream process to generate steam. These boilers are: compact, efficient, robust, modular and not subject to monitoring in many countries. The JUMAG waste heat boiler need not fear comparisons with large steam boilers: High heat exchanger output on a small area
A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.
The brittleness of cast iron makes it impractical for high-pressure steam boilers. Energy. The source of heat for a boiler is combustion of any of several fuels, such as wood, coal, oil, or natural gas. Electric steam boilers use resistance-or immersion-type heating elements.

VKK STANDARDKESSEL Köthen GmbH develops and supplies waste heat boilers for a wide range of thermal processes for generating steam or hot water with smoke-tube boilers. Our expertise in the constructive design of the heating surfaces forms the basis for meeting the high thermal, chemical and mechanical demands even in difficult process conditions.
A boiler is called a high pressure boiler when it operates with a steam pressure above 6.0 MPa. The high-pressure boilers are widely used for power generation in thermal power plants. In high-pressure boiler if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.
A heat recovery steam generator (HRSG) is an energy recovery heat exchanger that recovers heat from a hot gas stream, such as a combustion turbine or other waste gas stream. It produces steam that can be used in a process ( cogeneration ) or used to drive a steam turbine ( combined cycle ).
Gas & oil power plant boiler, waste heat steam boiler, CFB boiler, etc. the large scale boiler types can be designed as high pressure boilers, to generate high pressure high temperature steam for power generation or other steam process applications. Industrial High Pressure Boiler Features: 1.
· PDF fileBoiler water discharging as continuous blowdown contains both the sensible heat at boiler pressure and the latent heat content due to let-down from boiler pressure to near-atmospheric pressure. With a THERMGARD 2-stage blowdown heat recovery system, typically some 80% of this otherwise wasted heat content is saved.
The boiler feed water economizer is basically a gas-liquid heat exchanger located after the boiler evaporator section. The economizer also uses a portion of the energy contained in the thermal oxidizer combustion gases (after the waste heat boiler) to preheat the boiler feed water before it enters the boiler evaporator section.
A boiler is an appliance designed to heat water and produce energy. The heat is applied to water in an enclosed container before being distributed throughout the system. The major difference between a low-pressure and a high-pressure boiler is the amount of pressure per square inch and pounds per square inch gauge that the boiler produces.
Waste heat boilers High pressure waste heat boiler for the generation of high pressure hot water or high pressure steam. Waste heat boilers utilise the heat in flue gases from combustion processes or hot waste air flows from industrial processes to generate hot water or saturated steam.
This can be captured for cogeneration in a combined heat and power plant. This heat exits the engine at ~450 o C as ‘high grade heat’, contrasting to ‘low-grade heat’ available from the generator cooling circuits. This high temperature and flow makes it well suited for utilisation in a waste heat boiler.
